I've spend some time reading about cool things in PHP. I found some interesting functions and tricks. Here's the list:

1. You can compress/decompress long strings before storing them in a database. It can be done very easy using the built-in functions: gzcompress() and gzuncompress(). They use gzip algorithm and could compress a string up to 90%.

2. You can check if a email is valid by the checkdnsrr() function. It checks the email's host address if it's a valid DNS record.

For ex. tihomir@devtheweb12782.com is semantically a valid e-mail, but devtheweb12782.com is not a valid host. That's why checkdnsrr() will return false.
