preg_match help wanted

[SoloX]

Hi all:

I have strings like

PHP Code:

[media=34]filename.jpg[/media] 


I need to use preg_match or other PHP technique to get the two variables (34, filename.jpg) out. Can someone please help?

Thanks

Well I'm not a regex expert or anything but I thought I'd give it a shot:

PHP Code:


$pat = '@\[media=(\d+)\](.+)\[/media\]@';
$str = '[media=34]filename.jpg[/media]';
preg_match($pat, $str, $matches);

print_r($matches); 


output is:

Array
(
    [0] => [media=34]filename.jpg[/media]
    [1] => 34
    [2] => filename.jpg
)

You are a confirmed genius, my friend. It works like a charm.

Thank you very much.

I am greedy and back for one more and hopefuly last Q for this project.
My strings can be

PHP Code:

[media=34]filename.jpg[/media] 


or

PHP Code:

[media=34]http://www.d.com/filename.jpg[/media] 


From the first example, I got $match[2] as either filename.jpg or httP://www.d.com/filename. Lets say I put that in another variable $var. How would I check if $var starts with http or not.

Hmm...maybe:

if (strncasecmp("http:", $var, 5) == 0) {
   // This is a url
}

One thing I thought of that posting last night, it doesn't handle white space very well, it's possible to write a pattern that would ignore any white space on either end of the file name. (Or I guess you could also use trim() on the result if it were an issue).
