Question

I trying to understand if a isset is required during form processing when i check $_REQUEST[“input_name”] if no value is passed it doesn’t cry about it and php doesn’t throw out an error if you are trying to access a array item which doesn’t exist….i can use if($_REQUEST[“input_name”])..
what about “empty” even in those cases i can use if()

THnks

Answer 1

if($_REQUEST["input_name"])

will throw a notice (error) if “input_name” doesn’t exist, so isset() is recommended.
