Extracting string from file address

Question

I have string like "/files/temp/ABCDxyz-dfgdf.jpg"

I need to extract ABCD. First I'm trying to get the whole filename with this

$file="/files/temp/ABCDxyz-dfgdf.jpg";
$fileName=explode("files/temp/",$file)[0];

But it is not working.

Answer 1

Use basename to get the filename without the directory:

$filename = basename($file); // => ABCDxyz-dfgdf.jpg
$beginning = substr($filename, 0, 4); // => ABCD
