Screen Scraping

I need to pull some info off a certain website that is setup like this:

 

<b>Blah1:</b> 11<br/>
<b>Blah2:</b> 22<br/>
<b>Blah3:</b> 33<br/>
<b>Blah4:</b> 44<br/>
<b>Blah5:</b> 55<br/>

 

So I should be able to try:

 

echo "$blah1"; //value of 11
echo "blah5"; //value of 55

 

My code which doesn't work at all, hopefully somebody can improve on it:

 

// Get page
$url = "http://url.url.url";
$data = implode("", file($url)); 

// Get content items
preg_match_all ("/<\/b>([^`]*?)<br\/>/", $data, $matches);

// Loop through each content item
foreach ($matches[0] as $match) {
// First, get title
preg_match ("/<b>Blah1:<\/b>([^`]*?)<br\/>/", $match, $temp);
$title = $temp['1'];
$title = strip_tags($title);
$title = trim($title);
}
echo "$blah1";

 

Thanks for any future help, if you still don't understand lemme know.

Try:

 

<?php
$str="<b>Blah1:</b> 11<br/>
<b>Blah2:</b> 22<br/>
<b>Blah3:</b> 33<br/>
<b>Blah4:</b> 44<br/>
<b>Blah5:</b> 55<br/>";
preg_match_all('|Blah([0-9]).*?([0-9]+)|',$str,$matches);
$blah = array();
foreach($matches[1] as $k => $v){
$blah[$v] = $matches[2][$k];
}
echo $blah[1]; //11
echo $blah[5]; //55
?>

Awesome that does work. Now just one more question if you could.

 

How do I do it when there is no pattern to follow? For instance:

 

<?php
$str="<b>blah:</b> 11<br/>
<b>blah:</b> 22<br/>
<b>blah:</b> 33<br/>
<b>blah:</b> 44<br/>
<b>blah:</b> 55<br/>
";
?>
