preg_replace </color='#any hexadecimal color code'> to </color> in php

Question

I want to replace the

 </color='#any hexadecimal color code '>

to

</color>

I have tried following but nothing happened

$bio_info="some string </color='#any hexadecimal color code'>";    
preg_replace("/</color/", "</color>", $bio_info);

Nothing happened? You should have gotten an error complaining about unrecognized modifiers in the regexp, because you forgot to escape the /. — Barmar

Your regexp doesn't include the ='#any hexadecimal color code ' part of the tag that you want to replace. You also forgot to escape the /. And you need to assign the result to a variable if you want to use it.

$bio_info="some string </color='#any hexadecimal color code'>";  
$result = preg_replace('#</color=[^>]*>#', '</color>', $bio_info);

I've used a different regexp delimiter so I don't need to escape the /. [^>]* will match any sequence of characters other than >, so this matches the rest of the tag.

Simply fill with any char between opening and closing tag :

$bio_info="some string </color='#any hexadecimal color code'>";    
preg_replace("/<\/color.*>/", "</color>", $bio_info);
