Is it a bug or feature? :) Thanks. Reproduce code: --------------- $a = array(0 => "something"); $b1 = array(0 => "another"); $b2 = array(0 => "0"); $b3 = array(0 => null); $b4 = array(0 => 0); $a2 = array(0 => "two", 1 => "elements"); $b5 = array(0 => 0, 1 => 0); var_dump($a == $b1); // bool(false) var_dump($a == $b2); // bool(false) var_dump($a == $b3); // bool(false) var_dump($a == $b4); // bool(true) -- why array(0 => "something") // equals to array(0 => 0)? var_dump($a2 == $b5); // bool(true) -- it seems there are some regularity Expected result: ---------------- always bool(false) Actual result: -------------- bool(true) on something like array(0 => "one", 1 => "two") == array(0 => 0, 1 => 0) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46640&edit=1
