PHP的foreach多個陣列寫入csv文件

Question

我有以下數據重複5次想要回陣列和陣列寫信給我的csv文件：

<strong>Inventory number:</strong> 
    <input name="inv[]" type="text" size="10" id="inv[]"/> 
    <strong>Description:</strong> 
    <input name="des[]" type="text" size="30"id="des[]"/> 

    <strong>Inventory number:</strong> 
    <input name="inv[]" type="text" size="10" id="inv[]"/> 
    <strong>Description:</strong> 
    <input name="des[]" type="text" size="30"id="des[]"/> 

我做了一個foreach：

for ($i = 0, $rowcount = count($_POST['inv']); $i < $rowcount; $i++) 
    { 
$inv = $_POST['inv'][$i]; // get inventory 
$des = $_POST['des'][$i]; // get description 
     } 

然後有一個寫命令：

if(empty($errorMessage)) 
{ 
    $fs = fopen("data.csv","a") or die("Unable to open file for output"); 
    fwrite($fs,$sn . ", " . $givenname . ", " . $mail . ", " . $uid . ", " . $inv . ", " . $des . ", " . date("Y.m.d H:i:s") . "\n"); 
    fclose($fs); 

    $destination_url = "receipt.php"; 

    header("Location: $destination_url"); 
    exit; 
} 

，但只寫最後一個數組的CSV文件。

你能幫忙嗎？ 感謝

您必須通過遍歷數組，每個記錄寫入文件：

<?php 
if(empty($errorMessage)) 
{ 
    $rowcount = count($_POST['inv']); 
    $fs = fopen("data.csv","a") or die("Unable to open file for output"); 
    for ($i = 0; $i < $rowcount; $i++) 
    { 
     $inv = $_POST['inv'][$i]; // get inventory 
     $des = $_POST['des'][$i]; // get description 
     fwrite($fs, $sn . ", " . $givenname . ", " . $mail . ", " . $uid . ", " . 
      $inv . ", " . $des . ", " . date("Y.m.d H:i:s") . "\n"); 
    } 

    fclose($fs); 
} 

$destination_url = "receipt.php"; 
header("Location: $destination_url");
