Unexpected `&&` Syntax Error

Question

I'm not sure why this code is causing this syntax error but the error I'm getting is : Parse error: syntax error, unexpected '&&' (T_BOOLEAN_AND) in /srv/m/a-1.php on line 12

And the code:

if ($valid != FALSE) && (!isset($_COOKIE['set'])) {

What needs to be fixed?

Answer 1

丢失的 ”（”

if ( ($valid != FALSE) && (!isset($_COOKIE['set'])) ) {

Answer 2

You're missing a ( and final ) .

It should read

    if (($valid != FALSE) && (!isset($_COOKIE['set']))) {
