Playing with str_replace() function

Hi.

Recently, I'm playing with something related to BBCode in phpBB3. When I trace my database, the posts table and for a random post. I found that the image tag is written this way. There are 8 random characters generated between [img: ... ] for each post.

My question is, how can I make use of preg_replace() to replace the random characters into this way..

 

instead of str_replace use this

$your_bb_string = "[img:fcjsgy5j]";

print_r(sscanf($your_bb_string, "[img:%s]"));

 

You don't get me..

I want to convert [img:fcjsgy5j]http://imageurl.jpg[/img] to <img src="http://imageurl.jpg"> and fcjsgy5j is just a garbage value. Thanks.

 

<?php

function bb_img_to_html_img($string){
	$pattern = '#\[img\:.+\](.+)\[\/img\]#iUs';
	$replace = '<img src="$1" />';
	return preg_replace($pattern, $replace, $string);
}


print("\n\nTag test [img:sldkjsd]:\n");
$string = "[img:sldkjsd]http://www.somesite.com/image.jpg[/img]";
print(bb_img_to_html_img($string));

?>

PHP:

This matches the [img:sometext] pattern only - it won't replace img tags where the garbage text doesn't exist.

 

Okay irving, you just save my day. Million thanks!
