What is relationship between PHP and the elephant?

The elephant was chosen because one of the early adopters was into elephants.

While my friend Fran?ois who came to code at my home to show me what they could do with this “PHP”, in a deep thought, I was having fun By chance – chance sometimes do make good things happen – I suddenly noticed that the letters were forming the shape of an elephant if viewed in a ‘sideways angle’. Look at it well, you’ll see! I sent my first drawing to Jean-pierre Dezelus who I did not know at that time. He was a collector of elephant, this is amazing right? So he asked me to create an elephant in the same style as the true PHP logo.

A blue oval with a black outline gradient. I did what I had to do and we put this “elephant logo” for download on his website. While putting it online, I named the image file as elePHPant to play with the words a little bit (words’ pun).drawing the letters “PHP” in capital letters on a white sheet of paper.

As a bonus, the logo is commonly referred to as the "PHP elePHPant.
