Php array_map unlink check if file exists

Question

How do I check if the files exists in my array if I want to delete them with array_map + unlink:

// deletes all jpg files in that path

array_map('unlink', glob($path."/*.jpg"));

Right now if the folder does not contain any .jpg files I get an error, because there is nothing to unlink I want to catch that.

`glob($path."/*.jpg")` creates (is) the array – utdev Mar 08 '17 at 12:00 — utdev, Mar 08 '17 at 12:00

Your code should be:-

$filepath = __DIR__ . "/your_dir_name/" ; // Make sure this path is correct
array_map('unlink', glob( "$filepath*.jpg") ?: []); // check folder is empty or not

But where do I check here if the files exist? – utdev Mar 08 '17 at 12:15
You don't need to, because `glob()` will only return files that _do_ exist. – dearsina Mar 24 '21 at 17:16
