This implies that the results of the function should be the same whether or not the /e modifier is present. But the actual result is that preg_replace returns null if the modifier is there regardless of the RE or the target string. I have no particular problem with the behavior, but the documentation should reflect it. Test script: --------------- $x = "1 2 3 a b c 4"; $y = preg_replace("#\d#e", 'X', $x)); $z = preg_replace("#\d#", 'X', $x)); //documentation implies that $y == $z ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77848&edit=1
