php regular expression to capture number from table and load into variable

Question

So here is the string that im scraping a page to read (using file get contents)

<th>Kills (K)</th><td><strong>4,751</strong></td><td><strong>0</strong></td>

How can i navigate to the above section of the page contents, and then isolate the 4,751 inside the above html and load it into $kills ?

Difficulty: the number will change and have additional numbers before the comma

Answer 1

here you go

preg_match_all('|<th>.*?</th><td><strong>([\d,]+)</strong></td>|x', $subject,$match);
var_dump($match);

but if I were you I would use xpath it's is safer.

Answer 2

This should do it:

if (preg_match("/<th>Kills \(K\)<\/th><td><strong>([\d,]+)<\/strong>/", 
               $string, $matches)) {
  $kills = str_replace(",","",$matches[1]);
} else {
  $kills = 0;
}

Answer 3

This is what im using and gnarf's code returns 0

RageZ's returned an empty array

<?
$string = file_get_contents("http://combatarms.nexon.net/Community/Profile.aspx?user=tect0n");


if (preg_match("/<th>Kills \(K\)<\/th><td><strong>([\d,]+)<\/strong>/", 
               $string, $matches)) {
  $kills = str_replace(",","",$matches[1]);
} else {
  $kills = 0;
}
echo $kills;

?>

Coming up 0

Answer 4

Ok got it to work by removing all spaces and turning the page contents into a string

<?
$url = "http://combatarms.nexon.net/Community/Profile.aspx?user=tect0n";
$raw = file_get_contents($url);
$newlines = array("\t","\n","\r","\x20\x20","\0","\x0B");
$content = str_replace($newlines, "", html_entity_decode($raw));
preg_match_all('|<th>.*?</th><td><strong>(\d+,\d+)</strong></td>|', $content,$match); 
?>

This returns

Array ( [0] => Array ( [0] => Kills (K)4,751  [1] => Deaths (D)4,868  ) [1] => Array ( [0] => 4,751 [1] => 4,868 ) )

Answer 5

preg_match_all('#\(K\).*?<strong>(.*?)</strong>#s',$html,$matches);

tell me that aint pretty

Answer 6

preg_match('#<table class="tbl_profile">(.*?)</table>#s',file_get_contents('http://combatarms.nexon.net/Community/Profile.aspx?user=tect0n'),$m);
preg_match_all('#<tr>.*?<t.*?>(.*?)</t.*?>.*?<t.*?>(.*?)</t.*?>.*?<t.*?>(.*?)</t.*?>.*?</tr>#s',preg_replace('#(<strong>)|(</strong>)|(<!--.*?-->)#s','',$m[1]),$r);
echo 'You got '.$r[2][1].' killz';
//print_r($r);

now tell me thaaaaaaat aint pretty, cooooool it.
