我有一個解析頁面的23頁並獲取目錄名稱的腳本,但連接重置並超時。是因爲這個嵌套foreachloop for for循環嗎?For循環嵌套的Foreach循環問題
<?php
header('Content-type: text/html; charset=utf-8'); // this just makes sure encoding is right
include('simple_html_dom.php'); // the parser library
// you were trying to parse the wrong link.. your previous link did not have <div> tag with commentText class .. I chose a random link.. choose link for whichever professor you like or grab the links of professor from previous page store it in an array and loopr through them to get comments
$i=1;
for($i; $i < 23;$i++){
$html = file_get_html("http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=834&pageNo=$i"); // the url for the teacher rating profile
//your div tag has class "comment" not "commentText"
foreach($html->find("div[class=profName]") as $content){
echo $content->plaintext;
echo "<br >";
}
}
?>
將set_time_limit(0)用於循環 – 2013-05-11 04:27:37
如果連續23次請求,那麼可能會使您的IP被黑掉。 – 2013-05-11 04:30:17
