I'm trying to append a number of NULL characters '\0' to a string in PHP.
$s = 'hello'; while(strlen($s) < 32) $s .= '\0';
However, PHP adds 2 characters (\ and 0), instead of escaping the character and adding NULL. Does anyone know to add a NULL character to a string?
I don't know if
\0 is correct in your case, but you should use
$s = 'hello'; while(strlen($s) < 32) $s .= "\0";
