Answer 1

Use implode().

$yourArray = array_map("mysql_real_escape_string", $yourArray);

$query = "SELECT * FROM user_detail WHERE user_id='";
$query .= implode($yourArray, "' OR user_id='");
$query .= "'";

Or indeed, use the SQL IN keyword:

$yourArray = array_map("mysql_real_escape_string", $yourArray);

$query = "SELECT * FROM user_detail WHERE user_id IN ('";
$query .= implode($yourArray, "','");
$query .= "')";
