if a vairable doesn't equal another help

[Imad]

Hi guys, quick question. I'm trying to get an if function to work if two variables don't equal each other. What do I need to add?

Best Regards.

Use the not equal to comparison operator (!=)

 

if($var1 != $var2)
{
   // no match
}
else
{
   // match
}

Just keep in mind PHP's type conversion when comparing strings and numbers. For instance:

$a = 3;
$b = '3d';
echo ($a != $b);

will evaluate to false, while:

echo ($a !== $b);

will evaluate to true.
