Trying to convert old mysql code to mysqli - php

Question

I'm having to convert my inspection app to MySQLi but have been having many issues doing so since Amazon EC2 updated their MySQL
With not knowing much about php/mysql to begin with, I'm at a loss. Most of my searches have been way beyond what I understand.
This is what the file used to look like.
<?php
include("connect.php"); // Connect to RDS
$query="SELECT id, username, oldurl, homedata, clientemail, general_info, company_name, company_hours, company_phone, company_support_email, beyondscope FROM inspector WHERE username='{$_SESSION['username']}' ";
$result=mysql_query($query);
$num = mysql_num_rows ($result);
$username = mysql_result($result,$i,"username");
$oldurl = mysql_result($result,$i,"oldurl");
$homedata = mysql_result($result,$i,"homedata");
$clientemail = mysql_result($result,$i,"clientemail");
$general_info = mysql_result($result,$i,"general_info");
$company_name = mysql_result($result,$i,"company_name");
$company_hours = mysql_result($result,$i,"company_hours");
$company_phone = mysql_result($result,$i,"company_phone");
$company_support_email = mysql_result($result,$i,"company_support_email");
$beyondscope = mysql_result($result,$i,"beyondscope");
mysql_close();
?>
This is what I have so far. One error I'm getting line 17 has unexpected ',' (comma), even that every line has the same setup.
Thanks in advance for any help with this.
<?php
include("connect.php"); // Connect to RDS
$query="SELECT id, username, oldurl, homedata, clientemail, general_info, company_name, company_hours, company_phone, company_support_email, beyondscope FROM inspector WHERE username='{$_SESSION['username']}' ";
$result=mysqli_query($GLOBALS["___mysqli_ston"], $query);
$num = mysqli_num_rows($result);
$username = mysqli_fetch_array($result,$i,"username");
$oldurl = mysqli_fetch_array($result,$i,"oldurl");
$homedata = mysqli_fetch_array($result,$i,"homedata");
$clientemail = mysqli_fetch_array($result,$i,"clientemail");
$general_info = mysqli_fetch_array($result,$i,"general_info");
$company_name = mysqli_fetch_array($result,$i,"company_name");
$company_hours = mysqli_fetch_array($result,$i,"company_hours");
$company_phone = mysqli_fetch_array($result,$i,"company_phone");
$company_support_email = ($result,$i, "company_support_email");
$beyondscope = mysqli_fetch_array($result,$i,"beyondscope");
((is_null($___mysqli_res = mysqli_close($GLOBALS["___mysqli_ston"]))) ? false : $___mysqli_res);
?>
UPDATE: To add connect.php
<?php
$hostname='.rds.amazonaws.com';
$user='username';
$pass='password';
$dbase='dbasename';
$connection = ($GLOBALS["___mysqli_ston"] = mysqli_connect("$hostname" , "$user" , "$pass"))
or die ("Can't connect to MySQL");
$db = ((bool)mysqli_query( $connection, "USE " . $dbase)) or die ("Can't select database.");
?>

Answer 1

I've taken the liberty of rebuilding a bit on how you fetch your values, this should be a bit more easier to read and (in my opinion) a better structure. Also, you can specify the database in your connection, like this (just makes for easier reading, up to you really).
$connection = mysqli_connect($hostname, $user, $pass, $dbase);
if (!$connection) {
echo "An error occurred connecting to the database.";
exit;
}
Below is how your query could look. This will loop through all the results, and put them into the variables, only if we actually have a result.
<?php
include "connect.php"; // Connect to RDS
$query = "SELECT id, username, oldurl, homedata, clientemail, general_info, company_name, company_hours, company_phone, company_support_email, beyondscope FROM inspector WHERE username='{$_SESSION['username']}' ";
if (!$result = mysqli_query($connection, $query)) {
// An error occured, do something
// This means no results could be fetched
}
$num = mysqli_num_rows($result);
if (!$result) { // This means that we only fetch if we have a result
while($row = mysqli_fetch_assoc($result)) {
// Fetching all the rows
$username = $row['username'];
$oldurl = $row['oldurl'];
$homedata = $row['homedata '];
$clientemail = $row['clientemail'];
$general_info = $row['general_info'];
$company_name = $row['company_name'];
$company_hours = $row['company_hours'];
$company_phone = $row['company_phone'];
$company_support_email = $row['company_support_email'];
$beyondscope = $row['beyondscope'];
}
}
?>

Answer 2

JFYI.
There is absolutely no point in converting your inspection app to MySQLi the way it offered in the other answer.
The only point in such a conversion is to make your queries safe while with such a direct conversion it remained congenially vulnerable. So, you might saved yourself a lot of trouble by leaving this code alone, with exactly the same outcome.
Proper way is described in this answer, but you will have to find another volunteer to write a code for you.
