"."; taint($a); //must use concat to make the string not a internal string(introduced in 5.4) $b = str_replace("str", "btr"， $a); var_dump(is_tainted($b)); ?> Expected result: ---------------- bool(true) Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62395&edit=1
