PHP 8.0.0 Released!

pg_version

(PHP 5, PHP 7)

pg_version Returns an array with client, protocol and server version (when available)

Description

pg_version ([ resource $connection ] ) : array

pg_version() returns an array with the client, protocol and server version. Protocol and server versions are only available if PHP was compiled with PostgreSQL 7.4 or later.

For more detailed server information, use pg_parameter_status().

Parameters

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

Return Values

Returns an array with client, protocol and server keys and values (if available). Returns FALSE on error or invalid connection.

Examples

Example #1 pg_version() example

<?php
  $dbconn 
pg_connect("host=localhost port=5432 dbname=mary")
     or die(
"Could not connect");
     
  
$v pg_version($dbconn);
  
  echo 
$v['client'];
?>

The above example will output:

7.4

I note that the array element for "protocol" seemingly has no value, being reported as:

["protocol"]=> int(3)

whereas the array element for e.g. "server" is reported as (in my particular case):

["server"]=> string(5) "10.12"

A call to json_encode() however gives:

"protocol":3 and "server":"10.12"
