Scrape price PHP ( really easy ) but I can't lol

[bondigor69]

hey guys im using wordpress and In every post that I have there is a price

<strong>Online Price</strong>:$ 20.00<br>
<span style="color: red;">Your Price</span>:$ 17.91<br>

I want to get the second price (17.91) without dollar sign and space and ECHO it somewhere else.

Can someone help me please

PS every post have the same HTML above only price changing

If it's a standard format you can try substr(..), otherwise regular expressions but these functions take up more resources. By the way I don't see the problem you have echoing that variable...

try

 

insert the content example

 

$content = get_url("http://url-to-content");

 

preg_match("~<span style="color: red;">Your Price</span>:$(.+?)<br>~s", $content, $match);   

        $price = preg_replace("$","",$match[1]);

        $price = ltrim(rtrim($price));

       

        echo $price;

 

 

function get_page($url){

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    curl_setopt($ch, CURLOPT_HEADER, 0);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_URL, $url);

    $content = curl_exec($ch);

    return $content;

}
