Re^2: Checking for occurrence in comma separated string

Thanks Bart, I think your right. I was hoping on a simple if compairson method without using arrays etc, but it appears that the array method is the method I should be using for this.

Thanks...

You can also prepend and append a comma to your strings, and use index to quickly search for it. It may likely be faster than a dynamically built regexp. `if(index(",$thestring,", ",$thecheck,") >= 0) { ... }` [download] That will search for `",13,"` inside the string `",13,130,213,"`.
