Okay, there is webpage which I'm getting through file_get_contents.

 

The part I want to get is this

 

<td align="right" class="head-row">
<div id="numbertext">745</div>
<br><br>
<div id="numbertext">873</div>
<br><br>
<div id="numbertext">2324</div>
<br><br>
</td>

 

But, no all of that, you see the number 745? I'd need to be able to get that number by itself. Don't really need the other numbers, just the first number between the <div id="numbertext"> and the </div> tags. The thing is...the div '<div id="numbertext">' appears multiple times before AND after this block of code, but the '<td align="right" class="head-row">' only appears once, which is why I BELIEVE it needs to be..focused on.

 

Not sure though, basically..you see from the above code, I need to get that number 745 by itself. Thanks guys! ;D

<?php

$html = <<<HTML
<td align="right" class="head-row">
<div id="numbertext">745</div>
<br><br>
<div id="numbertext">873</div>
<br><br>
<div id="numbertext">2324</div>
<br><br>
</td>
HTML;
$replace = "|\\2|";
$new = eregi_replace("<div ([a-zA-Z0-9 \"=]+)>([0-9]+)</div>", $replace, $html);
$new = explode("|", $new);
foreach ($new as $v) {
  	if (is_numeric($v)) {
  		$numbers[] = $v;
  	}
}
print_r($numbers);
?>

 

Worked for me.
