Web ページから特定の要素を解析し、それらを mysql db に保存するスクリプトがあります。要素を分割し、結果のデータをデータベースに保存しようとするまで、すべて正常に機能します。何が間違っているのでしょうか?私が解析しているページは次のとおりです: http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=953
これが私のコードです:
<?php
include('simple_html_dom.php');
//connect to db (code emitted)
prof_List("http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=953");
function prof_name($url)
{
// collect data
echo $url;
$data = new simple_html_dom();
$data->load_file($url);
$profName = $data->find("//*[@id=profName]", 0);
$profName = strip_tags($profName);
echo "Full Name: " . $profName = trim($profName);
list($first, $last) = explode(" ", $profName);
echo "fname: " . $first;
echo "lname: " . $last;
//call mysql function
insert_row($profName, $first, $last);
}
function insert_row($profName, $first, $last)
{
$sql1="INSERT INTO PROFESSOR(name, firstname, lastname) VALUES('$profName','$first', '$last')";
$sql1=strip_tags($sql1);
echo $sql1;
mysql_query($sql1) or die(mysql_error());
echo "Data Inserted!";
}
function prof_List($mainURL)
{
$list = new simple_html_dom();
$list->load_file($mainURL);
$profLinks = $list->find("//*[@class=profName]/a");
foreach($profLinks as $profLink)
{
$profU=$profLink->href;
echo $profURL = "http://www.ratemyprofessors.com/" . $profU;
prof_name($profURL);
}
}
?>
ここに私の出力があります:
