In Firebird 1.5 this function INT64 returned to the fields created as floating point numbers. In Firebird 2.x this function returns as NUMERIC (SIZE, PRECISION). Example: NUMERIC (18,2)

Example:

$db = ibase_connect($host,$username,$password, "None", 0, 3 ) or die ('Error trying connect to Database!');



$select = "SELECT * from TABLE";    

$sql = ibase_query($db,$select) or die($select);



$total_fields= ibase_num_fields($sql);



for ($j = 1; $j <= $total_fields; $j++) 

  {

    $info_field = ibase_field_info($sql, $j-1 );

    print("Name: " . $info_campo[1]); // print the field name

    print("Type:". $info_campo[4]); //print the field type

    print("Size: " . $info_campo[3]); // print the field size

  }

This function does not return the type from the fields as we are accustomed in interbase.

Example: Fields VARCHAR are returns as VARYING. Fields of the type CHAR return TEXT.



Tested in Firebird 1.5 Super Server.
