提取iFrame显示的内容，将其保存在数据库中

Question

My issue is that I´m looking how to copy or extract a particular content of a website. I get the content from a external feed provider (Iframe format), the content is updated every minute. The Iframe updates new results and for instance, could show from 1 to 2 lines in the table in average at any moment.

Since the information showed by the feed is dynamic, I can´t look for old results. Thus, my goal, (if it´s possible) have a script to read/copy the content within IFrame periodically and it sends it to a MySQL database, within the hosting server. With this would be possible build a results history and be able to show old results.

What do you mean by "Iframe format".

If you mean an <iframe> Tag, then you can read the data by the given URL in the <iframe> Tag.

For example:

// Lets assume this is the Iframe
<iframe src="http://google.com/"></iframe> 
// You can see ^ the link where the iframe loads the data from.

// In PHP you could use file_get_contents($link) to return the result string, so...
$url = 'http://google.com/';
$var = filg_get_contents($url);

// $var stores now Googles generated index-file, like a simple GET-Request would do
echo $var;
