Php 命令行编程时出错

当我尝试使用命令行处理文件时：

cat texte.txt|php index.php

我有一堆奇怪的东西：

编辑：

这是我在92和104行之间的代码：

    $handle = fopen ("php://stdin","r");

    $N = $title = fgets($handle, 1024);


    while(!feof($handle))
    {
      if (!$order = fgets($handle)) continue;
      $all_orders[] = explode(',', $order);

    }

    foreach ($all_orders as &$order){

    $order["Order id"]=$order[0];
    unset($order[0]);
    $order["Deal id"]=$order[1];
    unset($order[1]);
    $order["Email address"]=$order[2];
    unset($order[2]);
    $order["Street address"]=$order[3];
    unset($order[3]);
    $order["City"]=$order[4];
    unset($order[4]);
    $order["State"]=$order[5];
    unset($order[5]);
    $order["Zip Code"]=$order[6];
    unset($order[6]);
    $order["Credit Card"]=$order[7];
    unset($order[7]);

    }

print_r($all_orders);

在foreach循环中，您正在访问数组值，而不检查它们是否存在

每次访问不存在的索引时，PHP都会给您一个通知——在您的例子中，是堆栈跟踪（我假设它是XDebug）。一个通知不是一个错误，你的脚本只是继续，并得到另一个通知，另一个，等等

您可以使用

isset（$order[$index]）

检查索引是否存在

此外，您的应用程序似乎正在读取CSV数据。如何使用php的内置程序来处理许多您的代码无法处理的边缘情况

顺便说一句，您的

foreach

循环是不必要的，您可以在读取记录后在while循环中进行处理。

index.php中的第92-104行是什么？您正在访问不存在的数组项。我已更新了代码，代码第92行到第104行有一个片段，我不知道，但它在一小时前运行良好，我没有更改任何内容。@Malek您在

fgets（）

调用中丢失了

trim（）

fgetcsv（）

，但是OP似乎对这个特定文件的行结束有问题，这导致

fgets（）

为每个其他记录返回空行。他在我之前给他的一些代码中缺少了一个

，这可能会再次给他空记录-。我已经建议过

，这些代码可能又给了他空记录-。
