當我嘗試處理與命令行文件：錯誤時，命令行程序

cat texte.txt|php index.php

我得到這個奇怪的堆棧：

編輯：

這裏是我的代碼在92和104之間：

$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);

index.php，92-104行是什麼？您正在訪問不存在的數組項。 – Maerlyn 2012-01-08 16:11:33

我已經更新了我的代碼，從我的代碼的第92到第104行有一個片段，我不知道，但是它在小時前很好地工作，我沒有改變任何東西。 – Malloc 2012-01-08 16:17:25

@Malek你從'fgets（）'調用中錯過了'trim（）' - 我猜你已經有幾個空的項目了[你在幾個小時前]（http：// stackoverflow。 com/questions/8777059）...'var_dump（$ all_orders）'確認;-) – DaveRandom 2012-01-08 16:24:25

在你的foreach循環中，你正在訪問數組值而不檢查它們是否存在。

PHP會在每次訪問不存在的索引時給你一個通知 - 在你的情況下，一個堆棧跟蹤（我假設它是XDebug）。通知不是一個明顯的錯誤，你的腳本只是繼續，並得到另一個通知，另一個，等等。

您可以用isset($order[$index])檢查索引'存在。

此外，您似乎正在閱讀CSV數據。如何使用PHP的內置fgetcsv()已經處理了許多邊緣情況下你的代碼不？

順便說一句，你的foreach循環是不必要的，你可以在讀取記錄後在while循環中完成那個處理。

我已經建議'fgetcsv（）'，但OP似乎有一個問題， fgets（）'爲其他記錄返回空行。他在我之前給他的一些代碼中缺少一個'trim（）'，可能會再次給他留下空白的記錄 - [見這裏]（http://stackoverflow.com/questions/8777059）。 – DaveRandom 2012-01-08 16:37:33
