Match last character in a string.

[citricsquid]

Let's say I have the following strings:

 

dsfdfsfdd/48977856+FE_F)E_E/dfhjdjhsd/sdffdsfsd/dsfsdfsdfp

dsfdfsfdd/123p

dsfdfsfdd/41234/1234324/3243223/324234

 

and I want to match the very final value after /, so It'd match:

 

dsfdfsfdd/48977856+FE_F)E_E/dfhjdjhsd/sdffdsfsd/dsfsdfsdfp

dsfdfsfdd/123p

dsfdfsfdd/41234/1234324/3243223/324234

 

I know how to find the first, but not the last! Thanks!

I'll assume you're somewhat familiar with how preg_match works (since you can find the first already) so will skip a longer explanation.  Essentially, you can use a regex which looks for the last set of non-forward-slash characters anchored to the end of the string (using $) like in the example below.

 

$subject = 'dsfdfsfdd/41234/1234324/3243223/324234';
preg_match('#[^/]+$#D', $subject, $match);
echo $match[0]; // 324234

 

Do feel free to ask if anything is unclear (like, "dude, what is that capital 'D' doing?!") or let us know if, god forbid, the pattern above isn't cutting it for you.

It those random strings are actually paths, you could also just use the basename function.
