I've installed Apache2 with php5 support and everything works there. I've installed PostgreSQL and am able to connect to it using the terminal and execute SQL statements.
PROBLEM: I can't get a working connection between my php scripts and the PostgreSQL database. I have installed the php5-pgsql packaged from the repositories, but the connection just won't work.
I get the following error message:
PHP Fatal Error: Call to undefined function pg_connect() in /var/www/[myfile].php on line [X]
How do I enable support for PostgreSQL connections in PHP5 in ubuntu 11.04?
EDIT: Checked phpinfo() and found no entries for PostgreSQL. I don't know why that is so, I DID install php5-pgsql package for ubuntu 11.04.
Here is what worked: I installed phppgadmin from the Ubuntu repositories. Not only does this make a nice tool available for me now, it also installed the needed packages for php to connect to postgresql.
After that, it was all in the connection parameters. It wouldn't connect to the database on the local server until I defined the connection host, port, database, user, and password in that order in pg_connect().
I still don't know why installing php5-pgsql on my own didn't enable PostgreSQL connections from php. Any input on this would be helpful.

Which PHP extensions need to be enabled for PostgreSQL? PHP 5.4 or higher is required: 5.4, 5.5, 5.6, 7.0, You need to chose between, PostgeSQL PHP extension and PostgreSQL PDO extension. You need to activate the extension you chose.
php $db_handle = pg_connect("host=localhost dbname=edb user=enterprisedb password=postgres"); if ($db_handle) { echo 'Connection attempt succeeded. '; } else { echo 'Connection attempt failed. '; } echo "<h3>Connection Information</h3>"; echo "DATABASE NAME:" .
PHP provides many functions for working directly with PostgreSQL databases. To connect to PostgreSQL using native functions, follow these steps: Use the following PHP code to connect to PostgreSQL and select a database.
pg_connect() opens a connection to a PostgreSQL database specified by the connection_string .
Install the php5-pgsql package solves the problem. (depending on the version ... php4-pgsql for php4)
apt-get install php5-pgsql Remember to restart Apache.
/etc/init.d/apache2 restart --Note that it might be hard if you do not administer your server.
