UPDATE MySQL table from a CSV using PHP - php

Question

I found and followed the directions contained within this StackOverflow thread: Update MySql Table from CSV using PHP
I've got an error somewhere that I'm unable to detect, I think there's a problem with my query, which works fine in actual MySQL but seems to not quite translate to PHP.
In short, I'm trying to UPDATE the value of several rows within a single table (catalog_product_entity_varchar) with CSV column $data[1], but only where certain skus are concerned AND attribute_id = 523 AND entity_id matches $data[0] of my CSV. Here's my code (actual PW/username, etc, obviously removed)
$con=mysqli_connect("localhost","username","password","some_db");
if (!$con){
die('Could not connect: ' . mysql_error());
}
if (($file = fopen("upload.csv", "r")) !== FALSE) {
while (($data = fgetcsv($file)) !== FALSE) {
$sql = "UPDATE catalog_product_entity_varchar
JOIN catalog_product_flat_1
ON catalog_product_flat_1.entity_id = catalog_product_entity_varchar.entity_id
SET catalog_product_entity_varchar.value='{$data[1]}'
WHERE catalog_product_entity_varchar.entity_id='{$data[0]}'
AND catalog_product_entity_varchar.attribute_id = 523
AND (catalog_product_flat_1.sku LIKE '%PR%'
OR catalog_product_flat_1.sku LIKE '%PT%'
OR catalog_product_flat_1.sku LIKE '%PF%')";
if (mysql_query($con,$sql)) {
echo "Updated!";
} else {
echo "Error updating " . mysql_error();
}
}
}
fclose($file);
It simply returns "Error updating" for every line of the spreadsheet. This query, when simply done in MySQL (without the PHP) and modified to have actual values instead of $data[1] or $data[0] works just fine. What am I missing?
If you're unclear of what I'm trying to achieve, I did post this question yesterday (trying to do it via pure mySQL) and there's more context here - https://stackoverflow.com/questions/21170245/updating-a-joined-table-in-mysql-from-a-csv

Wow.
So I feel stupid. Apparently mixing mysqli_connect and mysql_query doesn't work very well. Adding the "i" to the "mysql" of mysql_query solved it. Thanks for looking everyone!
