Ok, anybody like to suggest why the following:

 

if(isset($_GET['page'])){
	$page = $_GET['page'];
} else {
	$page = 1;
}

echo $page;

 

returns '1' when I go to file.php?page=43

 

But when I do this:

 

if(!isset($_GET['page'])){
	$page = 1;
} else {
	$page = $_GET['page'];
}

echo $page;

 

using the same query, I receive '43'.

That seems to defy logic - isset is returning both true and false with the same input?! Are you absolutely sure it has the same input and you've copied/pasted correctly in each example?

 

On a side note, you'd be better using either is_numeric() or intval() so you can simultaneously check if the value is in fact a positive integer. For example, this pretty much does what you want (I think - I haven't tested it):

 

if(($page = intval($_GET['page'])) <= 0) $page = 1;

Note intval() returns 0 if the argument cannot be parsed to an integer, and this test rules out all non-positive integers too.

Yeah I'm positive. I was staring at it for ages but then tested it on my localhost and it worked (as it should). I will change the code to use the functions you mentioned as it is a lot more efficient.

 

Do you recommend I contact my hosts about their PHP?
