[SOLVED] Var Type Question

[shane18]

I always wondered why

 

//CODE START

$user_id = $account_lookup[0]; //Value is 1

$BLAH2  = 1;

if($BLAH2 == 1){

//CODE END

 

comes out to be false

.....

 

then i figured out $USER_ID is a string... and $BLAH2 is a int.....

 

 

so my question is...

 

1. Do VAR TYPES matter in if statements all the time...

 

 

 

 

[trq]

PHP is smart enough (or stupid enough depending on how you look at it) to accept that '10' is the same as 10.

[shane18]

then why does

$USER_ID2 = 1;

if($USER_ID2 == "1"){

 

come out as false...

 

then when i do

 

$USER_ID2 = "1";

if($USER_ID2 == "1"){

 

it comes out as true

 

test it and see what happens..

[trq]

#!/usr/bin/php
<?php
$a = '10';
echo $a == '10' ? "true\n" : "false\n";
echo $a == 10 ? "true\n" : "false\n";

 

Results in....

 

true
true

can it be my version of PHP its 4.3.11, and also my results for the $USER_ID come from a mysql_fetch_row function.

[corbin]

if($USER_ID2 === "1")

 

Would be false.  but if($USER_ID2 == "1") wouldn't be false in any version of PHP.
