What I currently have,

$file = "1234123412341234 | 11218 | 9178814202";
preg_match('/(?P<5digit>[0-9]{5})$/D', $file, $match);
echo $match["5digit"];

Basically I want it to grab "11218". But instead it's grabbing 14202 from the other line. Is there any way to just get it to match exactly 5 digits and nothing else?

you just need the number between two pipe `|`? e.g 11218 – A l w a y s S u n n y Aug 04 '18 at 08:03
Pretty much, but it won't always be like that so I'm just trying to figure out how to grab exactly a 5 digit number... – Aug 04 '18 at 08:04
Because you putted a ending `$` sign, where from you want the 5 digits, from starging/ending/in beteen two pipe`|`? – A l w a y s S u n n y Aug 04 '18 at 08:07
Where would I put it? – Aug 04 '18 at 08:07

then just try `(?<= )[0-9]{5}(?= )`, that's it or with boundary `\b[0-9]{5}\b` but I think with your $file string it is possible with simple `explode()` – A l w a y s S u n n y Aug 04 '18 at 08:10

Try `\b[0-9]{5}\b` or to be more specific `\| *\K[0-9]{5}(?= *\|)`. See live demo here https://regex101.com/r/bY0VkI/1 – revo Aug 04 '18 at 08:11
If I use /[0-9]{5}/ then it grabs 12341 from the first part... It needs to grab an EXACT string that is ONLY 5 digits long. – Aug 04 '18 at 08:13
@revo I LOVE YOU. I spent like two hours trying to figure out how to get that to work... – Aug 04 '18 at 08:15
