opendir
(PHP 3, PHP 4, PHP 5)
opendir -- Open directory handle
Description
resource
opendir ( string path [, resource context] )
Opens up a directory handle to be used in subsequent closedir(), readdir(), and rewinddir() calls.
Parameters
- path
The directory path that is to be opened
- context
For a description of the context parameter, refer to the streams section of the manual.
Return Values
Returns a directory handle resource on success, or FALSE on failure.
If path is not a valid directory or the directory can not be opened due to permission restrictions or filesystem errors, opendir() returns FALSE and generates a PHP error of level
E_WARNING. You can suppress the error output of opendir() by prepending '@' to the front of the function name.
Examples
Example 1. opendir() example <?php
$dir = "/etc/php5/";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?> |
The above example will output something similar to: filename: . : filetype: dir filename: .. : filetype: dir filename: apache : filetype: dir filename: cgi : filetype: dir filename: cli : filetype: dir |
