併發文件寫入PHP

Question

我有一個偏執的客戶端項目......他擔心如果超過200人同時使用該站點，網站將崩潰。

我的腳本看起來好像會收集數據嗎？或者該文件會給用戶錯誤？

<?php 
if($_POST['name'] && $_POST['email']) { 
    //file name var 
    $fileName = "mycsvfile.csv"; 

    //grab from form 
    $name = $_POST['name']; 
    $email = $_POST['email']; 

    //date 
    date_default_timezone_set("America/Los_Angeles"); 
    $today = date("F j, Y, g:i a"); 

    //set the data we need into an array 
    $list = array (
     array($today, $name, $email) 
    ); 

    // waiting until file will be locked for writing (1000 milliseconds as timeout) 
    if ($fp = fopen($fileName, 'a')) { 
     $startTime = microtime(); 
     do { 
     $canWrite = flock($fp, LOCK_EX); 
     // If lock not obtained sleep for 0 - 100 milliseconds, to avoid collision and CPU load 
     if(!$canWrite) usleep(round(rand(0, 100)*1000)); 
     } while ((!$canWrite)and((microtime()-$startTime) < 1000)); 

     //file was locked so now we can store information 
     if ($canWrite) { 
     foreach ($list as $fields) { 
      fputcsv($fp, $fields); 
     } 
     } 
     fclose($fp); 
    } 

    //Send them somewhere... 
    header('Location: http://alandfarfaraway') ; 

}else{ 
    echo "There was an error with your name and email address."; 
} 
?>

使用數據庫（如MySQL）來存儲數據。它將處理更高的負載。
