pg_field_type

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

pg_field_type Returns the type name for the corresponding field number


Description

pg_field_type ( resource $result , int $field_number ) : string

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().

Parameters

result
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
field_number
Field number, starting from 0.


Return Values

A string containing the base name of the field's type, or FALSE on error.
