It is surprising to see how after all the code floating around people still find it hard to create random numbers. In a recent piece of code I encountered, the following was used to generate a string of random numbers. The code was written to provide a random string to be passed to a email verifier system - the type wherein a new user when he subscribes to a website needs to verify his email by clicking on a provided link.

He includes a snippet of the code that uses a call to str_shuffle on the set of numbers 1-10 to generate a random number. The only problem with the method is that, when the number gets large enough, PHP would automatically kick it into exponential format - not exactly ideal for an email link. Let this serve as a reminder for any scripts you might make that are similar.
