A Simple Unicode Decoder/Converter Function for PHP 5

June 18th, 2009 CodeBlink Leave a comment Go to comments

I wanted to use the unicode_decode PHP function for something I was working on today, but, of course, this function is only supported in the new PHP 6. I don’t know how it is for my fellow programmers reading this, but getting your I.T. department to upgrade all servers from 5 to 6 can be like getting your grandfather to change from a rotary phone to a iPhone. I.T. is uber apprehensive about such serious change. Their servers are their babies and ‘upgrade’ translates to ‘extreme security risk’ in their minds.

Don’t get me wrong, I love my company and my I.T. department, but when it comes to upgrading – I would be very thankful for a little more progressive thinking. At the same time, I understand the apprehension and can’t fault it completely, but PHP is no longer a light-weight in the world of server-side scripting.

Rant aside, I came up with this really simple function to help me decode Unicode text. Hope it helps!
