preg_match bbcode

I currently have bbcode like this

[caption=Some text goes here]image.jpg[/caption]

I'd like to use php's preg_match so I can get the value of the image.jpg, regardless of what's next to 'caption='. Can someone help me out?

RegExp is not magic. PHP already has a pre-made extension library to handle BBCode.

Don't reinvent the wheel, and don't make it hard on yourself.

If you want to match the complete bbcode tag, including the caption, use

preg_match("/\[caption=(.+)\](.+)\[\/caption\]/", $myString, $matches);

This will result in the following $matches array:

Array
(
    [0] => [caption=Some text goes here]image.jpg[/caption]
    [1] => Some text goes here
    [2] => image.jpg
)

You can use this regex:

$str = '[caption=Some text goes here]image.jpg[/caption]';
if (preg_match('/^\[[^\]]+]([^[]+)/', $str, $arr))
   echo "image: $arr[1]\n";

OUTPUT

image: image.jpg

Raw regex:

]([^\]]+)[/caption]

preg_match("]([^\]]+)[/caption]", myString, $matches)

image.jpg would be in the first group. $matches[1] (I'm not certain I escaped it correctly in php).
