Just a Simple Quick Question. I want to replace the Double Spaces at the begenning of the line by Tabs. Currently I am trying with preg_replace('~^( {2})~', "\t", $text) but that replaces only the first occurrence of Double Space.

- EDIT -

preg_replace('~PATTERN~', "REPLACEMENT", "      HalloWorld")
//Should be equal to "\t\t\tHallo World"
