如何將多個html頁面解析爲字符串？

Question

我想解析多個html頁面的代碼到一個字符串，使得像一個緩衝區，並閱讀此字符串，以便找到一個特定的文本輸入，everthing是好的，唯一的問題，是我無法將頁面加載到字符串中並讀取之後。

$url = 'http://www.test.com/'; 
$start = 0; 
$end = 1120; 

$counter = $start; 
while ($counter <= $end) { 

    /*** a link to search - add the counter value and html to the end of url ***/ 
    $link = "$url$counter.html"; 
    /*** get the links ***/ 
     $data = file_get_contents($link); 
     $data = $data.$data; 
//  echo $data; 

    $counter = $counter + 15; 

} 

有人能幫助我在這種情況下？

$url = 'http://www.test.com/'; 
$start = 0; 
$end = 1120; 
$counter = $start; 
$data=""; 
while ($counter <= $end) { 
    $link = "$url$counter.html"; 
    $res = file_get_contents($link); 
    If ($res!==false){ 
     $data .=$res; 
    } 
    $counter = $counter + 15; 

}
