hello beginner!
what i understand is that you want to pick data from postgres tables and display on your web page (in a read only format) is that ok?
for this you need to:
1. connect to your database
2. query it fetch data
3. use php functions to read data and then echo it.
an example but it is about mysql,you can check out for similar functions for postgres in the manual at www.php.net.Look under postgres functions in function reference.
$query="select * from table_name";
$result=mysql_query($query);
while($row=mysql_fetch_rows($result))
{// do something with data
}
hope it helps!
