Returns the name of the next entry in the directory. The entries are returned in the order in which they are stored by the filesystem.
The directory handle resource previously opened with opendir(). If the directory handle is not specified, the last link opened by opendir() is assumed.
Returns the entry name on success or FALSE
on failure.
This function may return Boolean FALSE
, but may also return a non-Boolean value which evaluates to FALSE
. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
Please note the fashion in which readdir()'s return value is checked in the examples below. We are explicitly testing whether the return value is identical to (equal to and of the same type as--see Comparison Operators for more information) FALSE
since otherwise, any directory entry whose name evaluates to FALSE
will stop the loop (e.g. a directory named "0").
<?php if ($handle = opendir('/path/to/files')) { echo "Directory handle: $handle\n"; echo "Entries:\n"; /* This is the correct way to loop over the directory. */ while (false !== ($entry = readdir($handle))) { echo "$entry\n"; } /* This is the WRONG way to loop over the directory. */ while ($entry = readdir($handle)) { echo "$entry\n"; } closedir($handle); } ?>
<?php if ($handle = opendir('.')) { while (false !== ($entry = readdir($handle))) { if ($entry != "." && $entry != "..") { echo "$entry\n"; } } closedir($handle); } ?>
