Need help with a Loop

I am using this code to retrieve text from a url, what I am having trouble with is I need to loop through the page and return each instance of the text requested.

I would appreciate some help.

function between($start, $end, $source) {
        $s = strpos($source, $start) + strlen($start);
        return substr($source, $s, strpos($source, $end, $s) - $s);
}

$data = file_get_contents('http://www.url-here.com/');
$string = between('<td class="table">', '</td>', $data);

Code (markup):

 

function between($start, $end, $source) {
$string = '';
while( $s = strpos($source, $start) + strlen($start))
{
$string .= substr($source, $s, strpos($source, $end, $s) - $s) . "<br>";
}
return $string;
}

 

I appreciate the response...I however couldn't get it to work. I did get this code to work, the only problem is I need it in an array. I need to be able to refer to each instance it finds with like 'echo $data[5];' or something?

I would greatly appreciate the help as I am in a pinch.

$fp = file_get_contents('http://www.url-here.com/');
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
	$out = "GET / HTTP/1.1\r\n";
	$out .= "Host: www.yahoo.com\r\n";
	$out .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12\r\n";
	$out .= "Connection: Close\r\n\r\n";
 
	$str = "";
  
	
		$str .= $fp;
	}
	

 
$pos = strpos($str, "<table id=\"idhere\"");
$pos = $pos + strlen("<table id=\"idhere\"");

if($pos == false) {
	echo "No information available";
}
else {
 
	while(1) {
		$pos = strpos($str, "<td class=\"classhere\">", $pos);
 
		if($pos === false) {
			break;
		}
 
		$pos = $pos + strlen("<td class=\"classhere\">");
		$temppos = $pos;
		$pos = strpos($str, "</td>", $pos);
 
		$datalength = $pos - $temppos;
 
		$data = substr($str, $temppos , $datalength);
		
	}
 
}
