PHP exec() function not working

Question

I am using macbook-pro, and i am executing this php script using apache server, but i am not getting the output of exec() function. It is not even showing any error. Can anyone tell me how to get the output. Thanks in advance.

<html>
<head>
<title>Online PHP Script Execution</title>
</head>
<body>
<?php
   echo "<h1>Hello, PHP!</h1>";
   echo exec('java -version');
?>
</body>
</html>

You sure you do not get the expected return from exec()? This sounds a little like you did not read the functions documentation. It does not return the output of the command you execute. — arkascha

yeah, i have read the documentation and exec() returns the last line of the output, the above script is working on online php compiler and it is giving the java version as output. but it is not working on my computer neither it is giving any error. — Sumit Kumar
