PHP regular expression for AWE/MERL 5101

I’m trying to write regular expression for the next pharse "AE/ME 5101" or "AWE/ME 5101" or or "any text or no text AWE/MERL 5101 any text or no text"

I need to catch "AWE/MERL 5101" or "AE/ME 5101" or "AWE/ME 5101" in the string or the string can have only this pharse. Anyway i need extract it. I’m trying to use /[A-Z]{1-4}/[A-Z]{1-4}/ but it doesn’t work

Any help

    $pattern = '/^[A-Z]+/[A-Z]+(?: [A-Z]+)? d+$/';

$strings = [
    "AE/ME 5101",
    "ECE/CS 673",
    "RBE/CS 526",
    "PY/RE 716",
    "RBE/CST 5265"
];

foreach ($strings as $string) {
    if (preg_match($pattern, $string)) {
        echo "$string is a valid match.<br>";
    } else {
        echo "$string is not a valid match.<br>";
    }
}

    I suggest you use the possible variations of your string inside a bracket, and to avoid collisions use another character – suggested here ~ – as the pattern delimiter:

    $pattern = '~(AE/ME|AWE/ME|AWE/MERL) 5101~';

    Check:

    $matches = [];
var_dump(preg_match($pattern, 'foo AWE/ME 5101 bar', $matches));

    Result:

    int(1)

    If you need the actual text that matched, this is available in $matches[0]
