Srting related help needed

    Need help, please help me out:

    a string is "test-5248-87dd133a6d" or "abc-def-5248-87dd133a6d". I am trying to take out only the "test" or abc-def" from the string.

    Or Trying to remove "-5248-87dd133a6d" part from the string. rem: -5248- is constant, "-87dd133a6d" is variable.

    Thank you.

    Assuming that your string is in a variable called $s...

    $s = "test-5248-87dd133a6d";
    $endPos =
    strpos($s, "-5248-87dd133a6d");
    $s = substr($s, 0, $endPos);

    For more info on how this works, do a Google search on "php strpos" and "php substr".

    this should work, 2 methods

    $string = "test-5248-87dd133a6d";
    // Remove all after test
    // Simply find -5248- and any character after it and remove it
    $new_string = preg_replace('/-5248-.*/', '', $string);
    // Remove all before constant -5248-
    // Match every character ( . ) and repeat ( * ) as long as its followed by a given string, but dont include string in match ( ?=string ) This is a posibive lookahead
    $new_string = preg_replace('/.*(?=-5248-)/', '', $string);
