    pclose

    (PHP 4, PHP 5, PHP 7, PHP 8)

    pclose — Closes process file pointer

    Description

    pclose(resource $handle): int

    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.
