爲給定url獲取標題，正文和http代碼的函數？

Question

PHP函數用於獲取指定網址的標題，正文和http代碼？ Curl庫沒有解析和操作http頭文件的最佳機制，所以這個函數非常方便。對於需要這種功能的小型腳本來說，使用一些大而健壯的庫已經令人厭煩。

這裏是我的，捲曲這樣的功能：

<?php 
function get_url_data($url, $timeout = 5){ 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL,   $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_HEADER, true); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); 
    curl_setopt($ch, CURLOPT_AUTOREFERER, true); 
    curl_setopt($ch, CURLOPT_MAXREDIRS, 2); 
    curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13'); 

    $response = curl_exec($ch); 
    $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE); 
    $header = substr($response, 0, $header_size); 
    $body = substr($response, $header_size); 
    $headers = explode("\n", $header); 

    $code = 0; 
    if(isset($headers[0])){ 
     if(preg_match('/[0-9]{3}/', $headers[0], $matches)){ 
      $code = $matches[0]; 
     } 
    } 

    return ['code' => $code, 'headers' => $headers, 'body' => $body]; 
} 

echo '<pre>'; 
$timeout = 5; 
$url = "http://www.ebay.com"; 
$results = get_url_data($url, $timeout); 
print_r($results); 
echo '</pre>'; 

實例進行測試，做工精細，享受。
