PG_FIELD_TYPE(3)														  PG_FIELD_TYPE(3)

pg_field_type - Returns the type name for the corresponding field number

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

DESCRIPTION
       pg_field_type(3) 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(3).

PARAMETERS
	      o $result
		- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).

	      o $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);
	      ?>
