Question

Please could someone help me, i will be forever appreciative.

I’m trying to create a regular expression which will extract 797 from “Your job 797 (“job_name”) has been submitted”

or “Your Job 9212 (“another_job_name”) has been submitted” etc.

Any ideas? Thanks guys!

Answer 1

Are there any special conditions about grabbing the number?

To grab the first number, just use /\d+/ with preg_match.

if (preg_match('/\d+/', $subject, $match)) {
    $job_id = (int) $match[0];
}

Otherwise you could do something like the following which searches for a number preceeded by “job” (case-insensitive).

if (preg_match('/job (\d+)/i', $subject, $match)) {
    $job_id = (int) $match[1];
}

^{(There are better alternatves for this regex, but best to keep things simple at first.)}

Another option would be to move away from regular expressions into more basic parsing of a string:

sscanf($subject, 'Your Job %d ("%[^"]")', $job_id, $job_title);
// use $job_id and $job_title however you like

Of course, similar could be done with preg_match but it’s good to offer alternatives.
