thanks in advance...

Try to change *array_push($response["Signup"], $msg);* to *$response["Signup"][] = $msg;*. BTW, didn't find any syntax error or other mistake that could cause this error. Maybe some UTF-8 special " or ' character? — Ernani Azevedo, Oct 15 '18 at 19:32
Somewhere you put `$array_push(...)` by mistake. Voting to close as typo. — miken32, Oct 15 '18 at 20:15
The error is on line 33 of `cus_signup.php`. Posting `signup.php` and `functions.php` is not helpful. — Barmar, Oct 15 '18 at 20:40
Line 33 has `$array_push` where it should just be `array_push`. The error message is clear about that. — Barmar, Oct 17 '18 at 15:14
But you didn't post that line, so we can't see the problem here in the question. — Barmar, Oct 17 '18 at 15:16

change your code to this

if (check_customer_email($con, $email)) {
    $msg["status"] = 0;
    $msg["msg"] = "Email Already Exist";
    array_push($response["Signup"], $msg["msg"]);
 }
else {
    $sql = "insert into customer(cus_name, cust_email, cust_userpass,cus_mobile) values('$name', '$email', '$userpass','$phone')";
    if(mysqli_query($con, $sql)) {
        $msg["status"] = 1; 
        $msg["msg"] = "Values successfully Added";  
        array_push($response["Signup"], $msg["msg"]);
    }
    else {
        $msg["status"] = 0; 
        array_push($response["Signup"], $msg["status"]);
    }

}

and look docs too

Can you explain why they should change their code to that and how it would solve the problem? It's not apparent just from looking at the code. – Don't Panic Oct 15 '18 at 21:11
`array_push($response['foo'], ['bar', 'baz']);` is perfectly valid (given that the foo key is an array). I see no obvious issue with the OP's array_push code above. – Progrock Oct 16 '18 at 07:33
@TEFO your code removed my err but it still shoeing "{"Signup":[0]}"...its not addinf values in db.. – Breera Hanif Oct 17 '18 at 00:05
