[SOLVED] Using readir and only store jpg in array

[ifubad]

Using the function readdir to get a list of files, and only if the file is a jpg, then those files will get stored into the array. Would it be correct to use regex to check the extension?

You could, but it would probably be easier to just check the last 4 characters to see if they equal '.jpg'

 

if (str_to_lower(substr($filename, -4))=='.jpg') {
    echo "It's a jpeg!";
} else {
    echo "It's NOT a jpeg.";
}
