Few very useful PHP functions
In this post I would like to present a few PHP functions which I created for projects I worked on and which I found very useful many times.

I think there is a big chance you will find them useful too. If you do- please leave a comment, thanks!
PHP Error: unserialize() [function.unserialize]: Error at offset 118 of 512

PHP: Nice URL shortener to use from PHP
In this post I would like to present you a nice URL shortening service that you may use from PHP in a very simple way (perhaps simplest possible!).
Let’s say you want to shorten url like this:
http://www.my-website-is-here.com/index.php?subpage

PHP: Smarty: {foreach} doesn’t render my array
On one of the websites I work I couldn’t render an array in a smarty template. My code looked like this:
{foreach from=$myarray key=mykey item=items}
<h2>{$mykey}</h2>
{foreach from=$items item=it}

After doing some research I discovered that in order to use EXIF [...]
PHP: How to safely include file with possible parse errors?
Recently I had written a class and it had to save bits of information somewhere. I wanted to make the script installable just by placing it on a server so I didn’t want to use any database. Instead I figured out I should save the data in a simple file. I could use serialize and file_put_contents which is very easy to write, but modifying such files manually in a text editor is a nightmare. So I decided to save the contents in a PHP file.
Unfortunately if there is an error in such file you will get parse error when including it.
