Returning multiple expressions from a string?

Copy linkTweet thisAlerts:
Oct 30.2008

Hey, I don’t know if I worded that title right.

Basically I need to take a string…

sdfgjsdfg dfsgsd sdfg [sdfgsdfgsdf sdfg] dsfgsdf sdg [dfgd] sdfgsd

And return the stuff in the brackets. Probably to an array since there will be multiple occurances.

It seems like it shouldn’t be too tough but I’m already stuck.

@neilemrichOct 30.2008 — You could try ereg:
[code=php]ereg("([[a-zA-Z ]*])", $string, $return_array)[/code]

String being the string of data and the return_array is the array to put the results into. This is normally used for sticking different matches into an array so I'm not sure what it will do with multiple matches that are the same but it might work!

@xvszeroauthorOct 30.2008 — Hmm... something like that would probably have worked. One line of code as well.

I did get it working though, just sort of a more convoluted fix. I would do a search for the first [ and the first ] and get their positions in the string, then grab everything in between them, throw it into the array, and define the string as now being equal to everything from one position after the ] to the end. Keep looping until the string has no more [ ] in it.

It's about 15 lines of code where 1 probably works, but whatever... its working correctly.

@NogDogOct 30.2008 — As the ereg functions are generally considered deprecated in favor of the preg functions, I might suggest:
[code=php]
preg_match('/(?<=[)[^]+](?=])/', $text, $array);
[/code]

Success!
