I have a way to get the name of the columns of a table. It works fine but now I want to update to the new mysqli ? (I tried the mysqli_fetch_field but I don't know how to apply to this case and I am not sure if it is the wright option)

How to do the same with mysqli ? :

$sql = "SELECT * from myTable";
$result = mysql_query($sql,$con);
$id = mysql_field_name($result, 0);
$a = mysql_field_name($result, 1);

echo $id;
echo $a;

This is the way to implement this missing function:

function mysqli_field_name($result, $field_offset)
{
    $properties = mysqli_fetch_field_direct($result, $field_offset);
    return is_object($properties) ? $properties->name : null;
}

    echo $property->name;
}

Comments
  • If you are going to use mysqli, all functions need to be converted to it. You can't mix mysql and mysqli.
  • mysql_field_name is already ancient and unusable way. Why do you need them, by the way?
  • That is the question: how to convert all to the new mysqli
  • What is your goal? What for do you need field names?
  • If you use mysqli_fetch_assoc, to fetch the data, you will get the field names in the array, so you wouldn't need to query them separately. Also, it's generally considered good practice to list the fields you want in the query; ie use SELECT fieldname, fieldname, etc rather than SELECT *. If you do that, you'll already know what fields are in the results, so you wouldn't need to check back for the field list at all.
  • This is the correct answer according the deprecation notice in the documentation, but the original function returned False on failure, not null. Shouldn't you just forgo the ternary operator and do return $properties->name; ?
  • Just change null to false.
  • Sorry, I'm new in php and I don't understand your answer. How can I pick up just the title of the field, like in the example I give.
