Answer Source

You need to use MySQL IN operator:

Corrected SQL:

$query = "SELECT mobile_number FROM Master_table WHERE id IN(1,2,3)";


Select mobile_number from table where id is either 1, 2 or 3

Difference between = and IN is that with = you can compare only one value.

With IN you can compare with a set of values.

So, the flow of SQL is:

SELECT mobile_number FROM Master_table WHERE (id = 1 OR id = 2 OR id = 3)

Which is similar to:

SELECT mobile_number FROM Master_table WHERE id  IN(1,2,3)

As per OP's query, following is the updated code:

$query="SELECT  mobile_number FROM Master_table WHERE id IN( 1,2,3)" ;
$data=mysqli_query($mysqli,$query)or die(mysqli_error());
$mobiles = array();
  $mobiles[] = $row['mobile_number'];
    //echo $row['mobile_number'];
$mobilesStr = implode(',', $mobiles);
echo $mobilesStr;
