If this example is really trivial, you can just use a regular expression. For general HTML parsing, PHP has DOM support:



$dom = new domDocument();
$dom->loadHTML("<div id=\"global\"><p class=\"paragraph\">1800</p></div>");
echo $dom->getElementsByTagName('p')->item(0)->nodeValue;

You need to parse HTML. There are several ways to do this, including using PHP's XML parsing functions.

However, if it is a simple value (as you said above), I would use the following simple code:

// your content
$contents='<div id="global"><p class="paragraph">1800</p></div>';

// define start and end position
$start='<div id="global"><p class="paragraph">';
$end='</p></div>';

// find the stuff
$contents=substr($contents,strpos($contents,$start)+strlen($start));
$contents=substr($contents,0,strpos($contents,$end));

// write output
echo $contents;


Good luck!

preg_match_all('#paragraph">(.*?)<#is', $input, $output);

print_r($output);
