What does the <> operator mean?

**vinyl-junkie** · Jan 16, 2005 00:49

I've seen that in several posts lately. I don't have that listed in my PHP book and can't seem to find it in my searching. If you have code like this:

Code:

if ($a <> "whatever") {
//do something here
}

does it mean $a is equal to "whatever", not equal or what?

it is if $var is NOT EQUAL to whatever..

what's wrong with != for not equal?

Nothing wrong with it at all. In fact, that's what I normally use myself. I was just wondering about the other way of doing it.

The <> operator is more specifically for numeric expressions. As in meaning,

PHP Code:


 if(5 <> 10)

If 5 is bigger than or less than 10 the statment returns true.

Hrm. I personally use

!=
== or =
>
<

<> sounds confussing lol

It is confusing!
But as with most coding languages there are many different ways of doing the same things but with subtle differences for different scenarios....

= is an assignment operator. Also, don't forget the identical comparison operators

Pascal for example only supports <> and doesnt know !=.
