我的if语句中出现意外的T_BOOLEAN_AND错误

I have the following IF statement:

if (strpos($_SERVER['REQUEST_URI'], '/dev/mahjong/mahjong.php') === strlen($_SERVER['REQUEST_URI']) - strlen('/dev/mahjong/mahjong.php') ) {
    $style = "display: inline";
}
else {
  $style = "display: none";
}

This works great. Now I wanted to show a Facebook login screen when $style = "display:inline";

So I figured, I make another IF with an AND, so IF display = inline AND user is NOT logged in, set $fb_login = "display: inline";

I've cooked up this code:

if (strpos($_SERVER['REQUEST_URI'], '/dev/mahjong/mahjong.php') === strlen($_SERVER['REQUEST_URI']) - strlen('/dev/mahjong/mahjong.php') ) {
    $style = "display: inline";
}
else {
  $style = "display: none";
}

if ($style = "display: inline") && (!$user)) {
    $fb_login = "display: inline";
}
else {
    $fb_login = "display: none";
}

Problem is I get an error with this: Parse error: syntax error, unexpected T_BOOLEAN_AND

Also tried to use AND instead of && but it gave the same result. What am I doing wrong here?

    • Your assignment operator (=) should be a comparison operator (==)
    • There was an unneeded parenthesis ())
    • I also removed some unnecessary brackets around the 2nd condition
    if ($style == "display: inline" && !$user) {
        $fb_login = "display: inline";
    }
