我的if语句中出现意外的T_BOOLEAN_AND错误 [英] unexpected T_BOOLEAN_AND error in my if statement

问题描述

我有以下IF语句：

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";
}

这个功能很好。现在我想在 $ style =display：inline;

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

中显示一个Facebook登录屏幕，所以我想我使用AND进行另一个IF，所以如果display = inline AND user没有登录，请设置 $ fb_login =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";

我已经编写了这个代码：

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";
}

问题是我收到一个错误：解析错误： / strong>语法错误，意外的T_BOOLEAN_AND

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

还试图使用AND而不是& amp;&但是它得到了相同的结果。我在这里做错什么？

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

推荐答案

• 你的赋值运算符（ = ）应该是一个比较运算符（ == ）


• 有一个不必要的括号（）


• 我还删除了第二个条件下的一些不必要的括号。


• 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";
}
