PHP: change [img]src[/img] to <img src=“src” alt=“src” > with regular expression

Question

I want to change [img]src[/img] to <img src="src" alt="src" > with regular expression.

I found some examples which convert <img src=""> to [img][/img] but not my case.

Thank you!

Answer 1

$ret = preg_replace('#\[img\](.+)\[\/img\]#iUs', '<img src="$1" alt="img">', $ret);

But in general you want something like a dedicated phpBB script, or phpBB class. Even PHP itself got BBCode text processor: http://www.php.net/manual/en/book.bbcode.php

Answer 2

你可以测试一下

 $str= preg_replace('~\[img\](.*)\[\/img\]~si', '<img src="$1" alt="$1">', $str);

Answer 3

I beleive this article will help you with your problem...

http://thesinkfiles.hubpages.com/hub/Regex-for-BBCode-in-PHP

function parseCode($txt)
{
   // these functions will clean the code first
   $ret = strip_tags($txt);

   // code replacements
   $ret = preg_replace('#\[b\](.+)\[\/b\]#iUs', '<b>$1</b>', $ret);
   $ret = preg_replace('#\[link\=(.+)\](.+)\[\/link\]#iUs', '<a href="$1">$2</a>', $ret);
   $ret = preg_replace('#\[img\](.+)\[\/img\]#iUs', '<img src="$1" alt="Image" />', $ret); 
   $ret = preg_replace('#\[quote\=(.+)\](.+)\[\/quote]#iUs', '<div class="quote">$2</div><div class="quote-by">By: $1</div>', $ret);


   // return parsed string
   return $ret;
}
