Looking for some REGEX help in PHP -

i have string:

[color=gray]a bunch of text.[/color]

and write preg_replace removes between "[color=gray]" , "[/color]" -- if it's possible remove tags well, that's great, otherwise can simple replace afterward.

$str = 'dfgdfg[color=gray]a bunch of text.[/color]dfgdfgdfgfg'; $str1 = preg_replace('/\[color=gray\].*\[\/color\]/',"",$str); echo $str1;

or

if color not gray

$str = 'dfgdfg[color=gray]a bunch of text.[/color]dfgdfgdfgfg'; $str1 = preg_replace('/\[color=\w+\].*\[\/color\]/',"",$str); echo $str1;

php regex
