Re: [PHP] running C/Fortran progz via command line ? From: Mike Eheler (meheler <email protected>)
Date: 10/15/01

use the "passthru" function to execute a program, then use output
buffering to control it's output:

http://www.php.net/manual/en/ref.outcontrol.php

http://zend.com/zend/art/buffering.php

http://phpbuilder.com/columns/argerich20010125.php3

http://www.phpdev.com/view.phph/4.html

A small example:

<?php
ob_start();
passthru('ls -lA /usr');
$text = ob_get_contents();
ob_end_clean();
echo "<pre>" . htmlspecialchars($text) . "</pre>";
?>
