如何通过PHP中的shell_exec命令运行Java程序？

Question

I have a PHP Project with the name itext . Inside this folder I have a workspace folder. So the Path to the Java Class file is like this:

itext/workspace/sampleproject/checkFonts.java

I have an index.php file in itext folder. How can I execute the shell_exec command in the index.php for the java file located in the above path?

UPDATE:

As per the answer I tried out stuffs and executed the below code and it works but I am getting the below error:

$output = array();
exec('java workspace/itext/src/itext/CheckFonts 2>&1',$output);
print_r($output);

Error:

Array ( [0] => Error: Could not find or load main class workspace.itext.src.itext.CheckFonts )

You can specify any path relative to the file your code is running from. So from your index.php the path would be workspace/sampleproject

If you want to use the full explicit directory you can use realpath() function:

realpath('workspace/sampleproject');

Here's a guide to running Java at the command line for windows environment: http://www.skylit.com/javamethods/faqs/javaindos.html

Your example code might be:

$javaPath = realpath('workspace/sampleproject');
$output = shell_exec('C:\ProgramData\Oracle\Java\javapath\java.exe '
                     . $javaPath . DIRECTORY_SEPARATOR . 'checkFonts');`
