Hi all. Maybe I'm just getting confused by all the languages I'm trying
to work with! But, isn't:
if(!$var1 == $var2){
the same thing as
if($var1 != $var2){
#1 doesn't work, #2 does.
Thanks!
No.
The second is seeing if $var1 is not equal to $var2.
The first one is doing a "not $var1" is equal to $var2 - which will
change it from whatever it is into false. (It's currently set - so
that's true, you're switching that - so it becomes false).
$ cat test.php
<?php
$a = 5;
var_dump($a);
$b = !$a;
var_dump($b);
$ php test.php
int(5)
bool(false)
So the "not $var1" becomes false.
