String replacement question

[bola]

How can i create string replacement like this:
<a href="link"><img src="picture" align="center(left,right)"></a>
for example like this:
[L="link"][img align="align"]imagename.jpg[/img][/L]

Use PCRE functions

Well, I'd use a regular expression. Something like this

$st = '<a href="link"><img src="picture" align="center(left,right)"></a>';

// first we process <IMG> tag ...
$st = preg_replace('/<img src="([^"]+)" align="([^"]+)">/i','[img align="\2"]\1[/img]',$st)

// .. then <A>
$st = preg_replace('/<a href="([^"]+)">([^<]+)<\/a>/i','[L="\1"]\2[/L]',$st)

// note that the order is irrelevant

<?php
$string='[L="link"][img align="align"]imagename.jpg[/img][/L]';
preg_match("/\[L=\"([a-zA-Z0-9\.\-]*)\"\]\[img align=\"(align|center|left|right)\"\]([a-zA-Z0-9\.\-]*)\[\/img\]/",$string,$matches);
print_r($matches);
echo "<a href=\"$matches[1]\"><img src=\"$matches[3]\" align=\"$matches[2]\"></a>";
?>

you know, you'll never learn regexps if you don't try first....
