Hello, Whenever I declare an external variable and I don't supply any value to it. and try to run empty() it gives me an error stating that value unbound.
Stated error is right. but as per the requirement. If I have a variable and that variable doesn't have any value than it should give me result of empty() true. For eg. declare variable $a external; return empty($a) I am execute this query for that purpose only, whether $a is empty or not. If I initialize it with space or something than empty() gives me result false. might be I am missing something. Regards, -- *Kunal Chauhan* [email protected] [+918655517141]
