if(exclamation mark){

danielneri

if you have this code:

[PHP]
if($sql){
echo "hi";
}[/PHP]

compared to this:

[PHP]if(!$sql){
echo "hi";
}[/PHP]

difference being putting an exclamation before the variable that has to be if-ed (if you know what i mean)...if-ecuted

what does that do? adding an exclamation mark?

always wondered about it...

Python

Basically what that does is the opposite of equals to... Heres an example...

Normal version...
[PHP]if($name = "bob)
{
echo "name is bob";
}[/PHP]

[PHP]if($name != "bob)
{
echo "name is not bob";
}[/PHP]

Where you had this:

[PHP]if($sql){
echo "hi";
} [/PHP]

That means that if $sql is set then it will display hi... But put an exclamation mark in front of it then it means that if $sql is NOT set then display hi
