Re: Error while calling a function

I don't know all the details about how PHP compiles a program, but having your function definitions in an if-else statement that may not be executed looks suspicious to me. You've got if(!$Phone) {

    do something

} else {

    function is_phone() { ...blah, blah...}

} is_phone($Phone); If you don't hit the else block, your is_phone function is probably not defined. -Steve On Tuesday, December 18, 2001, at 07:26 AM, J.F.Kishor wrote:
