Furthermore, PHP is happy to parse strings of text as string literals given that there are no special characters in them (e.g. operators, $ for variables, semicolon, parantheses ...). So, writing ~‹§æ“Ö¢‹ö (the bitwise inverted version) instead of "#[A-z]#e" saves one byte, as it does not have to be quoted. | |
