Split string only once between sequence of letters and sequence of numbers

Question

I want to extract two substrings from a predictably formatted string.

Each string is comprised of letters followed by numbers.

Inputs & Outputs:

• MAU120 => MAU and 120
• MAUL345 => MAUL and 345
• MAUW23 => MAUW and 23

Answer 1

$matches = array();

if ( preg_match('/^([A-Z]+)([0-9]+)$/i', 'MAUL345', $matches) ) {
    echo $matches[1]; // MAUL
    echo $matches[2]; // 345 
}

If you require the MAU you can do:

/^(MAU[A-Z]*)([0-9]+)$/i

Removing i modifier at the end will make the regex case-sensitive.
