Answer 1

You can achieve this with a query like this:

$row = $db->getOne("SELECT count(*) as count 
                    FROM pica WHERE id = 1 
                    AND pic1 = 'picture1.jpg'");

if ($row['count'] > 0) 
{
     print 'message Verified';
}

Answer 2

Assuming you want to check $php_pic and $id are in same row or not

Do it this way :

Method 1

 /*Fetch records*/
      $sql = 'SELECT id,pic1 from gallery where id = $id';
      $rs= $mysqli->query($sql);  /* fetch details */

      $id = $rs['id'];
      $pic1 = $rs['pic1'];

    /* match using php */
        if ($id == $php_id and $pic1 == $php_pic)
        {
           /* they are in same row*/
        }

Method 2

   /*Fetch records*/
      $sql = "SELECT id,pic1 from gallery where (id = $id and pic1=`$php_pic`)";
      $rs= $mysqli->query($sql);  /* fetch details */
      $row_cnt = $rs->num_rows;             


    /* match using php */
        if ($row_cnt >= 1)
        {
           /* they are in same row*/
        }

Answer 3

You can use a condition for this:

   IF EXISTS (SELECT * FROM pica WHERE id=1 AND pic1='picture1') 
    SELECT 'verified' 
    ELSE 
    SELECT 'failed'
