Hi
Rizwan Here
Null is the Constant in PHP. it is use to assign a empty value to the variable like
$a=NULL;
At this time $a has is NULL or $a has no value;
When we declaire a veriable in other languages than that veriable has some value depending on the
value of memory location at which it is pointed but in php when we declaire a veriable than php
assign a NULL to a veriable.
