Hey,

 

Im trying make a way to check an input to make sure it only consists of "1,2,3,4,5,6,7,8,9,0 and . " I thought i could explode the number and check it to an array that has "1,2,3,4,5,6,7,8,9,0 and . "

 

I havent worked with arrays before so i dont quite know how they work or to go about this?

 

Any ideas cause im sure im not the first to ask for something like this

 

Thanks

It depends what you want to do:

 

1. Do you want to control the user input and return a "yes" or "no" whether it contains forbidden characters?

2. Or do you want to remove all forbidden characters automatically without letting the user know?
