if statements - are these the same

[Hailwood]

so basically here is a set of if statements that i am trying to optimize, can you please tell me if there are any differences in processing between them

 

 

if($id!="0"    && $status!=""           && $msg_body=="")
if($id != 0    && !empty($status)    && empty($msg_body))

 

 

AND

 

 

 

if($message_type == 0    && $msg_link_id != "0"   && $status==""         && $msg_body!="")
if($message_type == 0    && $msg_link_id != 0     && empty($status)    && !empty($msg_body))

 

 

AND

 

 

if($message_type == 0    && $msg_link_id=="0"    && $status==""         && $msg_body!="")
if($message_type == 0    && $msg_link_id == 0    && empty($status)    && !empty($msg_body))

here is a set of if statements that i am trying to optimize

 

These type of micro optimizations are generally a waste of time.

maybe so, but i am doing optimization on the entire code, so i might as well.
