Question

So I have a random of strings and I need to parse them, let’s take an example:

This string - DeleteMe please and some other text

So I want to find DDeleteMe please and some other text and remove it, because all I need is This string

Answer 1

So everything before the dash - or how does DeleteMe please and some other text qualifies to be deleted?

If so, you need no regex, you can do it with substr and strpos:

$string = "This string - DeleteMe please and some other text";
$string = trim(substr($string, 0, strpos($string, '-')));

You could also use explode():

$parts = explode('-', $string);
$string = trim($parts[0]);
