意外T_IF，数组中的 if 语句 - unexpected T_IF, if statement in array

unexpected T_IF, if statement in array

本文关键字：if 语句数组 IF 意外 | 更新日期: 2023-09-27

我不知道为什么我会收到解析错误：语法错误，第 6 行出现意外T_IF。

 $sf = array ( 
            "name" => $firstname . ' ' . $lastname,
            "email" => $email,
            "address" => $shipping_address_1 . if(!empty($shipping_address_2 )) { echo ", " . $shipping_address_2 }
            );
            print_r($sf);

我想检查 $shipping_address_2 是否不为空，如果不是，则显示它。

因为你的代码是错误的。不能在数组初始化中放置 if 语句。

不是 100% 确定，但您应该能够使用三元运算符...

"address" => $shipping_address_1 . 
    (!empty($shipping_address_2 )) ? 
        ", " . $shipping_address_2 : // This gets executed if condition is true
        ""    // This gets executed if the condition is false

替换

 "address" => $shipping_address_1 . if(!empty($shipping_address_2 )) { echo ", " . $shipping_address_2 }

跟

"address" => $shipping_address_1 . (empty($shipping_address_2) ? null :  ", " . $shipping_address_2)
