819 PHP 5 Script for a user editable Medical Dictionary

In the last blog post No. 818 here, Click to go to post No. 818 we have adventured into a Java 8 Code .java file creation for an offline usable, user editable medical dictionary with sample text. We now take up a php5 script for designing an online/offline user editable medical dictionary with a sample text file.

Some features of PHP Scripts.
1. PHP Scripts are browser-based, i.e. we have to use them with the help of browsers like Firefox, Google Chrome, Chromium, Opera, Safari etc.

ONLINE USE

2. For online use of php scripts, we have to upload php files, and the supporting data files to a host server who will give shelter to all our files. All the paid web-hosts normally allow php scripts on their servers. On the net, there are "Free" web-hosters also, with 'their advertisements' and without their advertisements. Often, they also give us a dub-domain name.

OFFLINE USE

3. For offline use of php scripts, and their testing, we need to install an apache server and php on our desktop. I have tested the following script with PHP5 supported by firefox web browser, and an apache2 server. The apache server has to be configured for localhost access with something like http://localhost/...php. For the sample medical dictionary text file, you can create your own sample medical text file with every word entry in the following model:

^`word: meaning.
^`word: meaning.
^`word: meaning.
^`word: meaning. Like this you can enter any number of words. "^" is used as a delimiter between one recorde and another record. ":' is used as a separator between 'word' and its 'meaning'.

Or if you want a sample text file, which I have designed, you can use the file given by me in our blogpost No. 817 (See link at the beginning) in the ybmedicdicti.zip file uploaded by me at SourceForge.Net. It has about 10,000 words collected from American Government websites. That file and the Java code is not for Commercial Use. It is for educational purposes. This PHP5 script is also intended for Educational Purposes only.

Question: Can we use this script for general dictionaries, Telugu Dictionaries?

Ans: This script uses a text file as data, with a delimiter "^". You can create any number of dictionaries. Not only medical dictionaries, but also general dictionaries. Both php5 and Java 8 support utf-8. If there are Telugu fonts on the Desktop, almost all browsers particularly Firefox and Google Chrome, Chromium support UTF-8 coding. Hence we can use even for Telugu Dictionaries.
Here is the script. This script contains both html and php tags. Unfortunately, at this blogspot web-page, all the script is not showing correctly. I am googling, to find ways to show these html and php tags correctly with syntax highlighting of tags, variables.

This script, you have to save as a php file in a text editor. It is to be saved in your public_html directory. In Ubuntu all versions, its default location will be /var/www. But /var/www is a secured area. File saving filesinto it, you have to use a sudo password.

818 JAVA 8 CODE (Part 1/2), FOR A USER CUSTOMIZABLE MEDICAL DICTIONARY

Some of my readers thought that our this blog is a spiritual blog filled with preachings, prayers Gods and Goddesses, and philosophical discourses, accompanied by some religious propaganda, which is not true. Those things, I shall handle separately. As available evidence uptodate does not provide adequate proof for the existence of God, I lean towards atheism (the word coined by me is: aguardianism (There is no guardian/creator-protector for this Universe). In the same way, for the problems of an extremely poor and highly over-populated country like India, I have identified 'Communism / Marxism / True Complete Socialism" as solutions, without parting with democracy. With these goals, I have planned to make a set 1000 posts at this blog covering not only atheism, TC Socialism, the Problems of Telugu language speaking people, and numerous other things ranging from Music to Herbal Medicine. Of late, my readers may find that there is a slow-down of posts here. The slow-down is not because there is a Writer's Block, but because I have been enamoured with educating myself in I.T. For the last some years I have been working on Javascript, and PHP Script. My work in PHP can be seen at ayyo.x10.mx, for which I have given links in the side bar. Now, the bug of Java 8 bit me.

I burnt some midnight oil in getting at least a little minimum skill in writing java 8 code, and compiling them into usable classes. I am an aficionado and connoisseur of Java 8, in the sense that I am not an expert/pundit in Java, but I am very enthusiastic about it, because it is platform-independent, unlike several Windows applications. In the process, I have visited many websites which contain tutorials of Java to study .java files. From this experience I find that there are many magnanimous netizens with generosity, volition, and willingness to share their experiences to new entrants and give their suggestions. I have benefited much from the study of Java codes available on Net. I must also express my gratitude to SourceForge.net which a Great Treasure House of Open Source Software.

Though my preferences lie with herbal remedies, I have a cognition and perception that in case of emergencies, Modern Medicine (also called allopathic medicine by Homoeopathic Practioners), ought to be our last resort. I have already written, with some reasonable analysis, that using Homoeopathic medicines will be like 'wearing talismans', because homoeopathic medicines do not contain medical substances, because they are lost owing to excess dilution during succusion and trituration. I have already written a few blog poss about the risks involved in using mineral Ayurvedic remedies which contain heavy metals like mercury, lead and strong chemicals like sulphur. About Herbal medicines, we shall handle separately.

When we go to modern medical doctors and hospitals, we get charged heavily. We also get lot of prescriptions. We throw our money in dispensaries of the hospials / medical shops, and we ourselves swallow/get injected or make our relatives to swallo or get injected. I always felt that there is a need for our School and College curricula to contain some subjects/papers/chapters on pathology, patho-physiology, Pharmacology and phytochemistry.

Though numerous pdf medical dictionaries, and online medical dictioanries are available on net, there is need for a user customizable Medical Dictionary, which can be used OFFLINE, on ALL PLATFORMS and OS-es. PHP Scripts are browser based, and are suitable for online use. We can also use them offline, provided we have an apache server, installed. Then we must know how to store php script files and data files on localhost.

For creation/design of a user-customizable offline medical dictionary, I felt that Java 8 will suit most. Keeping this in mind, I have designed one Java 8 code, which can be compiled to generate a java class. Here it is: //Java 8 Code for reading from a text-file, split it into bits, search in each bit for the search word, and then show the results. import java.awt.BorderLayout; import java.awt.*; import java.awt.Color; import java.awt.event.*; import java.io.*; import java.nio.file.Files; import java.nio.file.Paths; import java.nio.charset.StandardCharsets; import java.nio.charset.Charset; import javax.swing.text.*; import java.util.regex.Pattern; import static java.lang.System.*; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.UIManager; import javax.swing.*; import java.util.*; import javax.swing.text.AttributeSet; import javax.swing.text.SimpleAttributeSet; import javax.swing.text.StyleConstants; import javax.swing.text.StyleContext; import java.io.IOException; //Very important: Here I have given the userdefined classname as ybmedicdicti. You can given any name as you like. But make sure that your code is saved with the same .java file name. Example: you have given public class name as danieldicti. Then .java file name should be danieldicti.java. File names and class names are case sensitive. Java customs have a naming tradition for classes and files. As an amateur, I am not following it. //Simply, I shall prefer lower case for all things which are "user-defined". This is because, if we forget to press the shift button, we get an error report. Then valuable time will be wasted in debugging and re-testing. But pl note: Java library functions from jdk8 and jre will have everything in Mixed case, as can be seen from the above imports, and also in the following definitions and declarations. public class ybmedicdicti extends JFrame { public static void main(String[] args) throws IOException { //uframe is userdefined jframe JFrame uframe = new JFrame("Medical Dictionary Search using java"); //uupanel is userdefined upper jpanel. This conains the textarea for showing result. JPanel uupanel = new JPanel(); //ulpanel is user defined lower jpanel. This contains the text area for typing search word, and search button JPanel ulpanel = new JPanel(); //North locates the upper panel on top uframe.getContentPane().add(uupanel, "North"); //South locates the lower panel at bottom. uframe.getContentPane().add(ulpanel,"South"); //utarea is the user defined textarea for showing result. 20,50 are height and width. JTextArea utarea= new JTextArea(" ",20,50); //We add a jscrollpane to the text area, so that if the results exceeds the 20-50 size, there will be a vertical scroll. uupanel.add(new JScrollPane(utarea)); //ulrec is the user defined label. JLabel ulrec = new JLabel("Enter your search word"); //We add the label ulrec to the ulpanel ulpanel.add(ulrec); //We are setting the background color of label 'Enter Search Word' to yellow. ulrec.setBackground(Color.yellow); //We are making label opaque. ulrec.setOpaque(true); //utasearchword is the userdefined text area for typing the search word. 2 is its height, 15 is its width. JTextArea utasearchword= new JTextArea("Type here ",2,15); //We add the utasearchword to the ulpanel (lower panel) ulpanel.add(utasearchword); //ubrec is the jbutton for clicking to get the search word. JButton ubrec = new JButton("Get the word "); //We are setting button's color to pink. ubrec.setBackground(Color.magenta); //We are adding the button ubrec to the userdefined lower panel ulpanel. ulpanel.add(ubrec); //We are enlarging the font size of the Result window to 20. utarea.setFont(new Font("Courier", Font.BOLD, 20)); //We are setting the foreground color of Result window to white. utarea.setForeground(Color.white); utarea.setBackground(Color.black); //We are setting the linewrap of the Result window. utarea.setLineWrap(true); //Display the window. uframe.pack(); uframe.setVisible(true); ///////////////////////////////////////////////////////////////////////////////////////////////// //Now, we shall read the content of the text file which contains the words and meanings of the Medical Dictionary. ybmedicdicti.txt is the text file which has to be stored in the same directory as the ybmedicdicti class file. The words and meanings given in the text file are only samples. These words have been collected from courtesy .gov websites of Government of U.S.A. They hold the copyrights for them. //This seems to be available only on Java 8. The user defined variable usour reads the text file. String usour = new String(Files.readAllBytes(Paths.get("ybmedicdicti.txt") ),Charset.forName("UTF-8")); //We split the string obtained from the text file into an array, using a delimiter '^". uarr is the user-defined array obtained. It contains around 10000 records of words and meanings. String[] uarr= usour.split("\\^"); //This actionlistener will start working when we type the searchword in the search window, and click the 'get' button. ubrec.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { try{ //We shall say "Results" in the Result window utarea.setText("Results: "); //usrec is the userdefined variable, which get the text typed by us in the Search Window. String usrec = utasearchword.getText(); //We add ` to the searchword, because we want to restrict search only to the word portion. We have to avoid search in the meanings area, though it can also be done. By converting the search word into lower case, we are making the search case insensitive. String usrec2 ="`" + usrec.toLowerCase(); //This uresultno will give serial Nos. to the result. int uresultno = 1; //Now, we are searching all the elements in the array of about 10000 records, for the search string. Variable u is the starting record i.e. 0. It will go upto the length of the array. for(int u=0; u < uarr.length ; u++){ //We are converting the array element to lowercase, to make the search case insensitive. if(uarr[u].toLowerCase().contains(usrec2)){ //Now we are adding the result record to the Result Window. utarea.append("\n" + "Result No: " + uresultno + "\n" + "Record No: " + u + "\n\n"); utarea.append(uarr[u]) ; //Increasing the uresultno is, to show raised result no. uresultno++; } //endfor u loop } //end of ifusour contains } //end try //error catching method catch(InputMismatchException e1){ JOptionPane.showMessageDialog(null, "Sorry not found"); } //end catch } //endaction performed }) ; } //endpsvm } //endpc
