是否可以通过$ _GET获取空数组值？

Question

Is it possible to get empty array(array with 0 items) value via $_GET?

Is it possible with direct value setting?

count($_GET['param'])==0

Answer 1

If array is empty or containing values that doesn't matters. Just declare a variable and pass the $_GET[] to the variable.

for example,

$para=$_GET['param'];

and now

if(is_array($para))
{
//  

} 
else{
$para=new array();
}
