(PHP 4, PHP 5, PHP 7)

pclose — Closes process file pointer

Description

int pclose ( resource $handle )

Closes a file pointer to a pipe opened by popen().

Parameters

handle: The file pointer must be valid, and must have been returned by a successful call to popen().

Return Values

Returns the termination status of the process that was run. In case of an error then -1 is returned.

Note:

If PHP has been compiled with --enable-sigchild, the return value of this function is undefined.

Examples

Example #1 pclose() example

<?php
$handle = popen('/bin/ls', 'r');
pclose($handle);
?>

Notes

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.
