random-numbers

Hello guys,

I have done some searching but really haven't found what I'm looking for. What I would like to do is generate a random BUT unique 5 digit number and push whatever number into an img tag on my page.

For example when people come to my page this number would generate and get pushed into this image tag:

<img src="http://www.sample.com?randomNUM=12345" height="1" width="1" />

I have a mySQL DB and am looking to do this in PHP.

Thank,

Matt
