Hi !

@ gw1500se :  While it's complicated I don't think it would require a regex since it's also basic. 

@requinix : Since this is an input received via ajax, someone can try and doctor the input to try and break the code. Hence I had the == false as well. And since a string won't be equal to false, I am thinking that it may be necessary to check that the input received is indeed a string. Wouldn't that be so ? Would you still go ahead with your code that you pasted above?

Thanks !

It will be either a string or an array. If you want to protect against that, a simple is_string() will suffice.
