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);
?>
