PHP function similar to this JavaScript function

Question

I need a similar function in PHP for this JavaScript function

text = text.replace(/ffc/g, "Hello");

I think preg_replace will do, but i'm not sure how to write the expression..

I want the regular expression similar to /ffc/g which is above, What I need exactly is to match the full word and case when performing the replace...

Answer 1

$text = preg_replace('/ffc/', 'replacement text',  $subject);

The online manual for PHP is pretty amazing, and one of the languages best features:
