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(PgSql\Result $result, int $field): string

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.

Changelog

Version Description
8.1.0 The result parameter expects an PgSql\Result instance now; previously, a resource was expected.

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
