How to use an array of values from PHP in the 'IN' clause of mysql query?

Question

//get all id\'s of ur friend that has installed your application
 $friend_pics=$facebook->api( array( \'method\' => \'fql.query\', \'query\' => \"SELECT uid FRO         


        

Answer 1

There is no native support for that. Even the bound parameter APIs do not allow to use arrays for IN clauses. You have to construct the query with some helper code:

$friend_pics = array_map("mysql_real_escape_string", $friend_pics);
$friend_pics = "'" . implode("', '", $friend_pics) . "'";
"SELECT * WHERE user_id IN ($friend_pics)              "

A simpler alternative would be mysqls FIND_IN_SET() however:

$friend_pics = mysql_real_escape_string(implode(",", $friend_pics));
"SELECT * FROM fb_user WHERE find_in_set(user_id,'$friend_pics')     "
