Question

I need to SELECT with array list. $array_name contains:

Array ( [0] => gum.cn [1] => lol.com. [2] => ns1.blar.com [3] => test.com [4] => web.cn. )

print_r($array_name);

  $string = implode(',',$array_name);


    $tank = "SELECT url FROM `PHP`.`db` WHERE url LIKE '%{$string}%'";
    $result1 = mysql_query($tank); 
      while ($jwp = mysql_fetch_array($result1)) 
      {     
      echo $jwp['url']; 
      echo "<br>"; 
      }

Why don’t the above work? I search other example and the question is asking without using LIKE clause so no solution there. Please help, thanks in advance.

It doesn’t work because your query will expand to:

SELECT url FROM `PHP`.`db` WHERE url LIKE '%gum.cn,lol.com.,ns1.blar.com...%'

You have to modify your query a little:

$query_parts = array();
foreach ($array_name as $val) {
    $query_parts[] = "'%".mysql_real_escape_string($val)."%'";
}

$string = implode(' OR url LIKE ', $query_parts);

$tank = "SELECT url FROM `PHP`.`db` WHERE url LIKE {$string}";
