is_readable

(PHP 3, PHP 4, PHP 5)

is_readable -- Tells whether the filename is readable

Description

bool is_readable ( string filename )

Returns TRUE if the file or directory specified by filename exists and is readable.

Keep in mind that PHP may be accessing the file as the user id that the web server runs as (often 'nobody'). Safe mode limitations are not taken into account.

Example 1. is_readable() example


<?php
$filename = 'test.txt';
if (is_readable($filename)) {
    echo 'The file is readable';
} else {
    echo 'The file is not readable';
}
?>

Note: The results of this function are cached. See clearstatcache() for more details.

Tip: As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to Appendix M for a listing of which wrappers support stat() family of functionality.
