如何为我的自定义PHP搜索引擎索引页面到MySQL [关闭]

Question

I have a simple PHP script that searches a MySQL database table for the requested keywords. However I am trying to make a PHP script that given a URL will import that page and grab everything inside the "content" ID. Is this possible? If it isn't I am willing to use JavaScript/jQuery.

Thanks in advance :)

Let me know if you need anymore clarification.

Answer 1

Yes this is possible, i would suggest maybe using cURL.

You can then input a URL in and it will grab the page.

<?php

$ch = curl_init('http://finance.google.com/finance');

curl_setopt($ch,CURLOPT_HEADER,0); 

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); // Give us the page source

$cr = curl_exec($ch);

preg_match_all('/href="()"/i',$cr,$pm,PREG_SET_ORDER);

print_r($pm);

foreach($pm as $pv) echo $pv[1] . "
";

?>

You are going to want to edit that preg match to make sure that you get only what you want, you can then split it out and insert into a database.

Please be aware that this is not very bandwidth efficient.
