How can I run PHP code within a Java application?

Question

Calling PHP from Java

I was wondering how I could run PHP code within Java. Using the ScriptEngine, I am able to run JavaScript:

String code="print(5+5);"; //sample bit of code
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByExtension("js");
try {
    engine.eval(code);
} catch (ScriptException ex) {
    //catch statement
}

To run this, I imported the library javax.script.*. I believe to run PHP I would have to import a similar library, and change the third line of the code above to the extension php. Unfortunately, I don't know which library this is. I have Googled to try and find the answer, and came across the PHP/Java Bridge library but I don't think this is exactly what I'm looking for, as it is focussed on running Java through PHP (as far as I know).

I hope I haven't missed anything out, and any help would be greatly appreciated!

@NickolayRatchev or Edmund, one of you should go ahead and write up an answer for this since you both seem t ohave figured it out. — Windle, Oct 15 '12 at 20:36
@Edmund: You should post that as an answer, not as a comment. I went ahead and removed the "Update" section of your question, since it is in fact an answer to your own question — Niklas B., Oct 15 '12 at 20:40

The solution to this problem is to download the files JavaBridge.jar, php-script.jar and php-servlet.jar from http://php-java-bridge.sourceforge.net/pjb/download.php then import them into your class:

import javax.script.*;

import php.java.bridge.*;
import php.java.script.*;
import php.java.servlet.*;

Then the code can then be run as before:

String code="echo 5+5;"; //sample bit of code
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByExtension("php");
try {
    engine.eval(code);
} catch (ScriptException ex) {
    //catch statement
}

The three imports: import php.java.bridge.*; import php.java.script.*; import php.java.servlet.*; are useless, no? – Aubin Oct 15 '12 at 20:44

No, the `ScriptEngine` needs the three imports in order to run the PHP. – Edmund Gentle Oct 15 '12 at 20:47

How to read the output of php code (say if it returns of echos something)? – Jus12 Dec 04 '16 at 13:42
@EdmundGentle I don't want to start a new question since so many have been marked as duplicates but is this still possible? I've looked for about an hour now and I can't find `php-script.jar` anywhere on the internet. Is it s till required? Thanks. – 1Poseidon3 Mar 25 '19 at 21:09
@1Poseidon3 it looks as though they stopped using `php-script.jar` in v7. In [v6.2.3](https://sourceforge.net/projects/php-java-bridge/files/Binary%20package/php-java-bridge_6.2.3/exploded/) the file is in there. You may want to look at the docs to use the latest version. – Edmund Gentle Apr 05 '19 at 07:38
@EdmundGentle Oh I didn't see that. I'll give it a look. Thank you. – 1Poseidon3 Apr 16 '19 at 16:43
