<function>pg_fetch_result</function> returns values from a
|
|
<parameter>result</parameter> resource returned by
|
|
<function>pg_query</function>. <parameter>row</parameter>
|
|
is integer. <parameter>field</parameter> is field name(string)
|
|
or field index (integer). The <parameter>row</parameter>
|
|
and <parameter>field</parameter> specify what cell in the table
|
|
of results to return. Row numbering starts from 0. Instead of
|
|
naming the field, you may use the field index as an unquoted
|
|
number. Field indices start from 0.

PostgreSQL has many built in types and only the basic ones are
|
|
directly supported here. All forms of <type>integer</type>,
|
|
<type>boolean</type> and void
|
|
<!-- FIXME: is that still true? PHP supports boolean&null now... -->
|
|
<!-- Yes, supporting boolean&null breaks scripts. pg_fetch_array()
|
|
can be used instead. I might take of this issue with additional
|
|
ini directive. yohgaki@php.net -->
|
|
types are
|
|
returned as <type>integer</type> values. All forms of float, and
|
|
real types are returned as <type>float</type> values. All other
|
|
types, including arrays are returned as strings formatted in the
|
|
same default PostgreSQL manner that you would see in the
|
|
<command>psql</command> program.
