Join Bill Weinman for an in-depth discussion in this video Getting data from a table , part of PostgreSQL 9 with PHP Essential Training.
Retrieving data from your table with Postgres in PHP is simply a matter of…using an SQL query.…Let's take a look at how this is done in PHP.…We're going to make a working copy of the start.php here, and we're going to…name that retrieve, I before E. We'll go ahead and open that in the text editor.…Before you continue, it's important that you update the password in this file to…match the password you entered when you created the SID user in pgAdmin.…
You see here on line 14 I have foo.bar.…This is where you'll need to put the password for your SID user exactly as you…entered it in pgAdmin. And come down here to the "database operations go here."…The first thing we're going to do is we're going to use the query row and get a…row, which will be a associative array;…$db->sql_query_row("SELECT * FROM $tn WHERE animal = and the SQL placeholder,…which will get replaced with the string duck.…
