# pg_field_type

(PHP 4 >= 4.2.0, PHP 5)

pg_field_type — Returns the type name for the corresponding field number

### Description

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().

### 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.

### Examples

Example #1 Getting information about fields

`<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// Assume 'title' is a varchar type
$res = pg_query($dbconn, "select title from authors where author = 'Orwell'");
echo "Title field type: ", pg_field_type($res, 0);
?>`

The above example will output:

    Title field type: varchar
