IsNumeric Function?

Arc

In VB there is a function called Isnumeric which checks if a value is Numeric....If it isnt it returns false. Is there anything like this in PHP?

Also, say i have 30 txt fields and i want to check if they all hold numeric values...what is the best way to do this?

In VB I would do a Control loop and check each value...but in PHP do i have to do an IF statement with 30 comparisons?

IF (Not IsNumeric(txt1) OR Not IsNumeric(txt1) OR Not IsNumeric(txt1) etc.....)

THanks!😃

Yes, it is called is_numeric()

I would say you would need to loop to check all 30 variables.

OK thanks...I'm not sure how you would do a loop with these text fields though.

Place them into an array, then find the size of the array, then begin looping.
There are several looping control structures in PHP: [man]for[/man], [man]while[/man], [man]do.while[/man].

You might want to goto the http://www.php.net/manual/en/ to learn about the power of PHP. It may be a scripting language, but it is every bit as powerful as VB when you use it well.
