问题
I am completly new to databases and am trying to make a simple query to a postgreSQL database. Now the problem is that I don't really understand how things work. In my index.php I do
$dbconn = pg_connect("host=myhost port=5432 dbname=mydbname user=myuser password=mypass sslmode=require options='--client_encoding=UTF8'") or die('Could not connect: ' . pg_last_error());
And I am connected to the database. When I try to query it from another myphp.php
$query = "INSERT INTO public.account_recover_users VALUES ($mykey,$email,$name)";
$result = pg_query($query);
I get the error in the title description. What is the proper way to connect to the database so that I can access it from other files than index.php as well?
P.S. $mykey,$email,$name are 3 variables containing a key (randomly-generated), an email and a name.
