opendir
OPENDIR(3) 1 OPENDIR(3)opendir - Open directory handleSYNOPSIS
resource opendir (string $path, [resource $context])
DESCRIPTION
Opens up a directory handle to be used in subsequent closedir(3), readdir(3), and rewinddir(3) calls.
PARAMETERS
o $path
- The directory path that is to be opened
o $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(3)
returns FALSE and generates a PHP error of level E_WARNING. You can suppress the error output of opendir(3) by prepending '@' to the front
of the function name.

EXAMPLES
Example #1
opendir(3) 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 . $file) . "
";
}
closedir($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
