pg_connect致命错误使用PHP

Question

I have a Postgres 9.1 database running on a remote server. I am trying to help a programmer set up remote posting to a table using php on my hostgator account.

I have modified the pg_hba.conf file on my postgres server to allow all connections from the ip address of my hostgator server using a password.

On hostgator, I am using a linux account and have modified the php.ini file to enable the line:

extension=php_pgsql.so

I have also tried this line:

extension=php_pgsql.dll

both with the following error:

Fatal error: Call to undefined function pg_connect() in /home1/kipsoft/public_html/hfs_forms/connection.php on line 6

In order to enable the php.ini file for every domain, I did modify the .htaccess file as in the instructions:

# Use PHP55 as default
# Use PHP5 as default
AddHandler application/x-httpd-php5 .php
# BEGIN custom php.ini PHP55
<IfModule mod_suphp.c>
    suPHP_ConfigPath /home1/kipsoft
</IfModule>
# END custom php.ini

The connect script looks like this:

<?php
session_start();
//$link = mysqli_connect('localhost', 'root', '', '209.239.000.001');
//$link = mysqli_connect('localhost', 'myuser', 'mypassword', 'myforms');

$db_connection = pg_connect("host=209.239.000.001 port=5432 dbname=myforms user=myuser password=mypassword");

/*if (!$link) {
    die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
}*/

ini_set("memory_limit", "192M");
?>

Unfortunately, I know nothing about php and I think the programmer has no experience with postgres. Anything to help would be greatly appreciated.

Check if php-pgsql is installed. Run:

php –me

or

yum list installed | grep php

If you don't see pgsql installed install it by running as root:

yum install php-pgsql

Enable pgsql in php.ini - uncomment this line - note, that dll is for Windows only:

extension=php_pgsql.so

Restart apache:

service httpd restart

Check if php-pgsql is working now.
