pg_field_type

Returns the type name for the corresponding field number

Description

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

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
