php str_replace hex color

Question

how do you replace this string *#ff00ff Hello World *000000 to  Hello World  using str_replace?

Thanks.

$string = str_replace('*#ff00ff Hello World *000000', ' Hello World </span', $string); Seriously, what are you trying to do? What have you tried and did not work? — Leri

Watch out ' and ". Thus would have to be $string = str_replace('*#ff00ff Hello World *000000', " Hello World ", $string); But good question where the original problem there is (thus what did not function with str_replace there) — Thomas

$string = '*#ff00ff Hello World *000000';

$string = preg_replace('/\*#([a-f\d]{6})(.*)\*[a-f\d]+/', "<span style='color:$1'>$2</span>", $string);

echo $string;

can also be done like so:

$string = '*#ff00ff Hello World *000000';

$string = preg_replace('/\*#([[:xdigit:]]{6})(.*)\*[[:xdigit:]]+/', "<span style='color:$1'>$2</span>", $string);

echo $string;

$str = '*#ff00ff Hello World *000000';
preg_match('/(#[0-9a-f]{6})/i', $str, $matches);
echo "<span style='color:{$matches[1]}'> Hello World </span>";
