(PHP 4, PHP 5)
pclose — Closes process file pointer
handleThe file pointer must be valid, and must have been returned by a successful call to popen().
Returns the termination status of the process that was run. In case of an error then -1 is returned.
Example #1 pclose() example
<?php
$handle = popen('/bin/ls', 'r');
pclose($handle);
?>
Note: Unix Only:
pclose() is internally implemented using the waitpid(3) system call. To obtain the real exit status code the pcntl_wexitstatus() function should be used.
