PostgreSQL与PHP的连接不起作用

Question

I am trying to develop a basic page that uses PostgreSQL for the database. The database is already set. Right now I was simply trying to create a connection with it.

<?php
    echo "test 1";
    $dbconn = pg_connect("host='localhost' port='5432' dbname='demorole' user='demorole' password='eta'") or die ("couldnt connect");
    echo "test 2";
?>

demorole is my database and its owner user. eta is a sample of password (but is correct)

My problem is that this page doesn't work at all. It doesn't display any errors. When i use the function pg_connection_status() it doesn't return anything. It only prints "test 1" (the echo commands are for debugging purposes).

I am working on Linux Mint. Both PostgreSQL and Apache are running. The connection info are correct. Any idea what might be wrong? Because, since it doesn't display any errors, I'm stuck.

Answer 1

Make sure you have pgsql php extension installed.

And turn on error displaying in php.ini

display_errors = On display_startup_errors = On

Answer 2

This code worked.

 $host        = "host=127.0.0.1";                         
 $port        = "port=5432";                        
 $dbname      = "dbname=mydb";                         
 $credentials = "user=myrole password=mypsw";

$connection = pg_connect( "$host $port $dbname $credentials"  );
if(!$connection){  echo "Error : Unable to open database\n"; } 
 return $connection;
