example.com中有50 <span class='numer'></span>

使用此代码，我得到50 <span class='numer'></span>，但我想在example.com中获得前10个<span class='numer'></span>。我该怎么办？

 function srch($bas, $son, $article)
    {
      @preg_match_all('/' . preg_quote($bas, '/') .
      '(.*?)'. preg_quote($son, '/').'/i', $article, $m);
      return @$m[1];
    }

$link = "http://example.com/";
$inside = file_get_contents($link);
$sp = srch("<span class='numer'>","</span>",$inside);
for ($i=0;$i<sizeof($sp);$i++)
echo "$sp[$i]";
