[SOLVED] Querystring args count

[MeTitus]

Hi guys,

 

How can I get th number of arguments in the querystring?

 

eg: localhost?a=1&b=2 --> arguments count = 2;

 

Also if the argument a didn't exist I would get "" with $_GET["a"], how do I actually find whether it exists?

 

Many thanks,

 

MeTitus

you can get the count with

 

$count = count($_GET);

 

you check for

 

array_key_exists("a",$_GET);

 

hope its helpful
