What would be the best way to send NSData through PHP into MySQL? <p>Ok I believe this must be a pretty common scenario. I need to send a NSData variable over a HTTP request through a PHP page which then subsequently stores it in MySQL. This will be retrieved later by some other HTTP call which then downloads it into a NSData again. What is the best way to do this?</p> <p>Should I convert the NSData into some sort of string representation (base64 etc)? Should I store the data in MySQL as VARCHAR or Blob? The data length will not exceed the MySQL/HTTP limit.</p>
