php file regexp filter directory regular Expression


Versions (?)

Comfortable directory contents with filters

 / Published in: PHP
 

Very simple to use.

Calling:

$files = dirContents(DIR_PATH, [FILTER, [TYPE]]);

Examples:

$files = dirContens("my-dir");

$files is array containing all, both files either directories

$files = dirContens("my-dir", "img[0-9]");

$files is array containing files or directories with 'img0', 'img1', 'img2', etc. in their names

$files = dirContents("my-dir/", "\.php", 1);

$files is array containing only files with '.php' in their names

Tip: After calling dirContents() try to call print_r for showing the array of files

echo '<pre>';
print_r($files);
echo '</pre>';

Thank you for your comments.

you should use "sort()" only if the files match the pattern, or else you get an error: if(count($arrayOfFiles)>0){ sort($arrayOfFiles,SORTLOCALESTRING); }
