[Resolved] preg_match() or something?

[The Hobo]

In my table, there's a bunch of text that may contain image tags, such as:

[img]http://site.com/image.gif[/img]
[img align=left]http://site.com/image2.gif[/img]

What I need to do is is search through the whole text and extract all the images and put them in an array. So the above would give me:

http://site.com/image.gif
http://site.com/image2.gif

I've tried various things with preg_match() and preg_replace(), but I'm fumbling around.

With preg_match, it will still have the various [img] stuff in it and will be in one string, rather than an array. So there's a bunch of additional stuff I'd have to do to parse it.

Is there a better way?

Alright. I looked at the manual and learned that the PREG_OFFSET_CAPTURE flag will place the results in an array, so I got that problem covered.

So I'm running the following code:

<?php

    $body = 'Text here
    [img align=left]http://www.image.com/image.gif[/img]
    Text here
    [img align=right]http://www.image.com/image2.gif[/img]
    Text here
    &#91;img&#93;http://www.image.com/image3.gif&#91;/img&#93;
    Text here';


    echo '<div style="width: 500px;">
        <span style="font-size: 8pt;">
            <b>original text</b>:
        </span>
        <hr>' . nl2br($body) . '<hr>';

    echo '<br><span style="font-size: 8pt;"><b>the links</b>:</span><hr>';


    preg_match('/\[img(.*)\](.*)\[\/img\]/i', $body, $matches, PREG_OFFSET_CAPTURE);

    for ($i = 0; $i < count($matches[0]) - 1; $i++) {
        echo preg_replace('/\[img(.*)\](.*)\[\/img\]/i', '\\2', $matches[0][$i]) . '<br>';
    }


    echo '<hr></div>';

?>

But it only seems to catch the first link?

[The Hobo]

I suppose if I would have read the manual a little better, I would see that it says:

preg_match() returns the number of times pattern matches. That will be either 0 times (no match) or 1 time because preg_match() will stop searching after the first match. preg_match_all() on the contrary will continue until it reaches the end of subject.

Whoops.

But it still doesn't return the last link?

[The Hobo]

Holy cow. Kagey and I just wasted an hour on this...

for ($i = 0; $i < count($matches[0]) - 1; $i++) {
        echo preg_replace('/\[img(.*)\](.*)\[\/img\]/i', '\\2', $matches[0][$i]) . '<br>';
    }

I was skipping the last match. All that time and I thought it was messed up pattern syntax.
