pg_field_type — Returns the type name for the corresponding field number

설명

string pg_field_type ( resource $result , int $field_number )

pg_field_type() returns a string containing the base type name of the given field_number in the given PostgreSQL result resource.

Note:

If the field uses a PostgreSQL domain (rather than a basic type), it is the name of the domain's underlying type that is returned, rather than the name of the domain itself.

Note:

This function used to be called pg_fieldtype().
