WHY PHP cURL HTTP CODE return 0 (zero)

If you try to connect with the server, then you can get a return code from it, otherwise it will fail and you get ZERO.
So if you try to connect to “” you will get a return code of 400, if you go directly to, you will get 302 (and then 200 if you forward to the next page… , and if you go to “yahoocom” you will get a 0 (host no found), so with the last one, there is nobody to send a code back.

Tested using the code below.


What is the difference between $message and $$message?

$message is a variable and $$message is a variable of another variable.

$Message = “A”;
$A= “B”;

echo $message //Output:- A
echo $$message //output :-B

That is, a variable name which can be set and used dynamically.

We can echo above strings like

echo $Message.$A;

This weill print we “AB”

Note : variable’s value can be act as variable
