PHP pg_connect to PostgreSQL

Trying to use PHP to remotely query a PostgreSQL DB on my AWS server..


<?php

    if ( isset($_POST["searchText"]) )
    {
        $searchText  = $_POST["searchText"];
        $searchType  = $_POST["searchType"];
        $searchDb  = $_POST["searchDb"];
    }
   
    $query = "SELECT * FROM " . $searchDb . " WHERE " . $searchType . " = '" . $searchText . "';";
   
    $queryResult = query($searchDb, $query);
    //echo $queryResult;
 
    function query($searchDb, $query)
    {
        $host = "wouldntyouliketoknow.com";
        $user = "username";
        $pass = "password";
        $db = "database";
       
        pg_connect("host=$host port=5432 dbname=$db user=$user password=$pass");
       
        if (!$conn)
        {
            echo "Not connected";
        }
   
        $result = pg_query($conn, $query);
        pg_close($conn);
        return $result;
    }
   
?>

It doesn't throw any errors, the connection request just times out every time after like 15 seconds, then it just echoes "Not connected." Is this an issue with the AWS server, or the server I'm trying to open the connection from?

Jesus christ, that's insecure as hell, man.
I suppose you're still learning, but as a rule you should _never_ create query strings like that.
Use prepared statements or whatever they're called in your language of choice.

Sounds like it's an issue with the server.
But I don't really know
