如何使用preg_match获取数组中的字符串格式链接url .html？

Question

I have a sample code:

$array = array(
   1 => "tag/gomobi.html", 
   2 => "game.html", 
   3 => "game.php", 
   4 => "game.html", 
   5 => "game/game-mobile/feed.html"
);
foreach ($array as $url) {
   if(preg_match('/^((.*)\.html)(.*?)$/', $url, $matches)) {
       echo $matches[1].'<br />';    
   } 
}

But result can't remove value same (game.html)

tag/gomobi.html
game.html
game.html
game/game-mobile/feed.html

How to fix it, with result is:

tag/gomobi.html
game.html
game/game-mobile/feed.html

Answer 1

Try:

$array = array(
   1 => "tag/gomobi.html", 
   2 => "game.html", 
   3 => "game.php", 
   4 => "game.html", 
   5 => "game/game-mobile/feed.html"
);

print_r (array_unique($array));

Answer 2

Use array_unique(); . It removes duplicate values from an array

print_r(array_unique($array));
