What is the difference between $ _ GET and $ variables? for example, what are the differences between the two methods that can be used to receive incoming parameters para1 $ _ GET [para] and $ para from another page?? ------ Solution ------------------ $ _ GET is a global variable and receives a form submitted in get mode. $ para is just an ordinary variable. ------ Solution ------------------ what is the difference between the $ _ GET and $ variables in the quality zone?
For example, the input parameter para = 1 is accepted from another page.
What are the differences between $ _ GET ['para'] and $ para?
------ Solution --------------------
