I'm trying to extract data (text) from an external site and put it on my site. I want to get football scores of an external site and put it on mine. I've researched and found out I can do this using Preg_Match but i just can't seem to figure out how to extract data within html tags.
For example
this is the HTML structure of an external site.
<td valign="top" align="center" class="s1"><b>Text I Want To Fetch</b></td>
How would I fetch the text within tags? Would help me out allot! THANKS!
You can get the content of a webpage by using file_get_contents method.
Eg:
$content = file_get_contents('http://www.source.com/page.html');
Try this:
<?php
$html = '<td valign="top" align="center" class="s1"><b>Text I Want To Fetch</b></td>';
$dom = new DOMDocument();
$dom->loadHTML($html);
$dom = $dom->getElementsByTagName('td'); //find td
$dom = $dom->item(0); //traverse the first td
$dom = $dom->getElementsByTagName('b'); //find b
$dom = $dom->item(0); //traverse the first b
$dom = $dom->textContent; //get text
var_dump($dom); //dump it, echo, or print
In this example, there weren't any other textContent, so if your HTML only has text within bold, you may use this as well:
<?php
$html = '<td valign="top" align="center" class="s1"><b>Text I Want To Fetch</b></td>';
$dom = new DOMDocument();
$dom->loadHTML($html);
$dom = $dom->textContent;
var_dump($dom);
if you're talking about using php to fetch data, then file_get_contents(url) may help; however, you can fetch data using AJAX request with Jquery too. Down here is the link to AJAX documentation: http://api.jquery.com/jquery.ajax/
