Php 使用逗号进行分析时出现分析错误

我得到了这个错误：

分析错误：语法错误，意外的“$array\u of_line”T_变量，第7行的C:\wamp\www\site6\book-utilities.inc.php中需要函数T_

我尝试使用两个类来读取单独的文件，客户文件应该被读取，每一行都被读取到一个数组的新实例中。订单文件应读入订单对象数组

这就是我现在所拥有的，我这样做是错误的吗

<?php



class readOrders{

$array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
  foreach($array_of_lines as $line) {
 $pieces_of_line = explode(',', $line); 

}

class readCustomers{
$array_of_more_lines = fopen("customers.txt", 'r') or die("Failed to create file");
  foreach($array_of_more_lines as $line) {
 $pieces_of_line = explode(',', $line);

}


?>

customers.txt

每个文件有多个类通常是不好的做法。该问题可能是由于两个类上的foreach循环缺少一个结束的花括号造成的：

class readOrders{
   public function __construct(){
       $array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
       foreach($array_of_lines as $line) {
           pieces_of_line = explode(',', $line); 
       }    
   }
}

class readCustomers{
    public function __construct(){
       $array_of_more_lines = fopen("customers.txt", 'r') or die("Failed to create file");
       foreach($array_of_more_lines as $line) {
          $pieces_of_line = explode(',', $line);
      }
    }
}

类只能在大括号{}之间直接具有方法和属性定义。而且，您没有关闭foreach循环

似乎要在构造函数中运行代码：

class readOrders{

    public function __construct()
    {
        $array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
        foreach($array_of_lines as $line) {
            $pieces_of_line = explode(',', $line);
        } 
    }

}

这对类来说是有效的语法吗？这不应该被包装在一个带有返回的公共函数中吗？你是100%正确的，整个结构在发布的代码中是无效的。我假设他没有发布所有的代码/遗漏了明显的错误。错误消息指出了缺陷aha，相应地更新你的答案，从MEA获得+1。你应该阅读php中的类和对象：对于构造函数来说，返回或设置内部变量是最好的吗？目前它正在修改值，但没有use@MattTingle您能否详细说明您希望如何与这两个类交互，以及这两个类所需的数据结构？你有订单类还是想使用stdClass？好吧，我将把客户数据显示到一个表中。顺便说一句，这确实有效，没有错误，我的死亡消息也没有显示。

class readOrders{

    public function __construct()
    {
        $array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
        foreach($array_of_lines as $line) {
            $pieces_of_line = explode(',', $line);
        } 
    }

}
