pg_field_type
(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
pg_field_type — Returns the type name for the corresponding field number
Description
pg_field_type() returns a string containing the
base type name of the given field in the
given result instance.
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().
Parameters
-
result -
An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
-
field -
Field number, starting from 0.
Return Values
A string containing the base name of the field's type.
