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.
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)
In Brazilian Portuguese:
No Firebird 1.5 esta função retornava INT64 para os campos criados como numéricos com ponto flutuante. No Firebird 2.x esta função retorna como NUMERIC(TAMANHO, PRECISAO). Exemplo: NUMERIC(18,2)
