I'm trying to hash passwords for our company site. After testing on a local Apache server that has PHP 5.5.9 and everything working as expected, I went to test on our live server being hosted by GoDaddy. The problem is that when I run my code there, it doesn't work. A `phpinfo()` statement revealed that the version is **PHP 5.3.24**.

This presents a bit of a problem because the modern hash functions that I see for PHP, like `password_hash()`, were written in PHP 5.5 or newer. I don't really see many resources for password encryption for anything older than **5.3.7** and I think it's probably wisest to update.

Are there PHP password hashing functions for 5.3.24 or should I ask my boss to consider updating the server? Aside from accessing the local Apache server, the GoDaddy server is out of my hands except for FTP access, so I have no clue if this is something we can update or not.
