int matchNumber(int $numtomatch, int $num1[, int $num2...])

This function compares a number to a list of numbers to see if $numtomatch matches any of the numbers in the list. If $numtomatch does not match any numbers, then the function will return 0, else the function returns 1 or greater. For instance, if $numtomatch matches $num1, then the function will return 1, if $numtomatch matches $num2, then the function will return 2, etc.

This function is supported only in CSE HTML Validator v10.00 and later.
