A quick Filegetcontents and explode on \r\n will get you each line of the csv. Then explode in commas to get every field. Now you can loop through and build the insert or update queries you need.

i wrap all fields in the mssqles (ms sql escape string) I made below. It trims and escapes quotes and also gets rid of a chr(31) that pissed me off at some point.
function mssqles($string_to_escape) {
	$replaced_string = str_replace("'","''",trim($string_to_escape));
	$replaced_string = str_replace(chr(31),"",trim($replaced_string));
	return $replaced_string;
}

I put my stock functions in a file called inc.php
if it's in the same folder, just do:
require_once("inc.php");
at the top of your page.

Then you call the function like in the code below when you build your query:

 
$query = "insert into tablename (column1,column2,column3) values(";
$query .= "'".mssqles($column1)."','".mssqles($column2)."','".mssqles($column3)."');";

Since you're new to this, I'll also mention that you can do a bunch of rows with one insert statement.
Insert into tablename(column1,column2,column3) values (1,2,3),(4,5,6),(7,8,9)

Damn, I just noticed you are using mysql. Forget my function. Thats for microsoft sql. PHP already has a function built in:
mysql_real_escape_string();
So just replace my mssqles in the example with mysql_real_escape_string
