str_replace problem

Copy linkTweet thisAlerts:

Hi,

I have a script that replaces html tags with BB code, however I am getting a problem when doing the <li> tags.

if I do this, the code works:

[code=php]$bb_map = array(“<li>” => ‘[LI]’);

$string = str_replace(array_keys($bb_map), $bb_map, $string);[/code]

However if I do this the code does not work:

[code=php]$bb_map = array(“</p><li>” => ‘[LI]’);

$string = str_replace(array_keys($bb_map), $bb_map, $string);[/code]

Any ideas

Thanks in advance,

Ben

The only thing I can see is that in the second case you are looking for: "</p><li>" not only "<li>". So maybe your $string var doesn't contains the "</p><li>" string.

If you want a more flexible way to do it, you should use preg_replace instead of str_replace.

Something like this should do the job:

[code=php]
$bb_map = array( '/(</p>)?<li>/' => '[LI]' );

$string = preg_replace( array_keys( $bb_map ), $bb_map, $string );
[/code]
