Php preg_match code to split string ending with numbers

considers a string that is based on the following : 1. can contain any alphanumeric characters 2. the string ends with number(s)

Now by using preg_match($expression, $subject, $parts) I want to split the string in such a manner that the ending numbers and the rest of the string is stored in the $parts array separately.

for example: kim2bn88 should result in two parts: kim2bn and 88

But I am not able to figure out the regex. Kindly help!

Solution

  • I think you want a regex like as follows:

    /^(\w+)(\d+)$/

    Assuming you always have non-digits before the final digits.

    This gives you two capture groups. The first are word characters (alphanumeric + _) at the start of the string. The second are digits at the end of the string.
