Checking Contents of a .txt Fles

Good morning,

My web application requires users to upload data in the form of comma-seperated values

i.e. 11,3, 8,12,5 ,1,9, 13,5,7

I want to check that the user is only uploading numbers and commas

What is the best way to check this?

Regular expressions?

Thanks

Yes, Regex

Thanks, would you be able to expand on that and give me some example code?

Cheers

[man]pcre[/man] (and your example contains digits, commas and spaces; so that's

/^[0-9, ]+$/

)
