help with regex

[aebstract]

I have a string, something basically like:

 

$string = "a lot of text a lot of text a lot of text a lot of text a lot of text [[image.jpg]] a lot of text a lot of text a lot of text a lot of text  [[image2.jpg]] a lot of text a lot of text a lot of text a lot of text [[image3.jpg]]";

 

I'm needing to grab the first [[*]] value in the string, remove it from the string and set it as a variable, $firstimage.

Then I'll need to just delete all of the others from the string. Could someone help me with this, are there any real good resources for regex online? Thanks

Couldn't you use strpos with substr?

 

Something like this

$firstimage = substr($str,strpos('['),strpos(']));

Ended up being a bit off of what you have, gonna be an equal pain in the ass to do the second part like this, but oh well.

 

$firstimage = substr(substr($article, strpos($article, '['), strpos($article, ']')), 2);
