PHP Deleting images

I have an admin system which adds profile pages dynamically - and part of that adds images to a directory. When I add the images they all have the name format like 12_1.jpg, 12_2.jpg, 32_1.jpg, 32_9.jpg where the number before the underscore is the id $cid and the number after the underscore is the image number.

I'm trying to find a way to list the images on the edit-images.php page with an option to delete them (maybe a link next to the image name, or another way that is better).

Here is the code to find the images I need to have the option of deleting:

if ($handle = opendir('../images/company')) {
    while (false !== ($entry = readdir($handle))) {      
      if (substr(basename($entry), 0, 2) == $cid) {
        echo $entry . "<br>";
      }
    }
    closedir($handle);
}

How would I go about deleting specified images from here? Any help would be appreciated.

Why are you scanning the directory for the file? You can check if the file exists and delete it instead. For example:

$files = glob("../images/company/$cid_*.jpg");
foreach($files as $file) {
  if(file_exists($file)) unlink($file);
}

This will unlink all files in ../images/company with the name starting with 123_ for example and ending in .jpg (you can provide more extensions by using GLOB_BRACE parameter)

In php you use the unlink function to delete files. Just echo a link to a page that calls a function do to that and pass the image name. Only be sure to check the user input before actually perform deletion.
