I need to count the number of images in a directory for a loop. Right now I am using this:

 

$dir = "folder/".$client."/";
$count = 0; //can adjust starting number if needed
if(is_dir($dir)) {
if($handle = opendir($dir)) {
while(($file = readdir($handle)) !== false) {
$count++;
}
closedir($handle);
}
}

 

That works great for getting a $count on everything in the directory, but I just want to count all the jpg files (jpg, JPG, jpeg, JPEG) in the dir.

Using glob would be much easier, especially since it allows for you to choose. Look into that, it would be something like:

 

<?php
$dir = "folder/".$client."/";
if(is_dir($dir)) {
    $images = glob($dir . "{*.jpg, *.JPG, *.jpeg}");

    echo "There are " . count($images) . " inside of {$dir}.";
}
?>
