如何判断变量是否为数字以及是否为偶数？ [关闭]

Question

I need my script to tell me if a variable is numeric, and if it is, whether or not it's an even number. My code thus far:

        $Numbers = array("1", 2, "three", 4, 5, "six");

        foreach ($Numbers as $Value) {
            if (is_numeric($Value)) {
                if ($Value % 2 == 0) {
                    echo "$Value is numeric, and even";
                } else {
                    echo "$Value is numeric, but not even";
                }
            } else {
                echo "$Value is not numeric";
            }

My browser is displaying a blank page.

Any help would be greatly appreciated.

Syntax error.Close foreach loop

 $Numbers = array("1", 2, "three", 4, 5, "six");

        foreach ($Numbers as $Value)
        {
            if (is_numeric($Value))
            {
                if ($Value % 2 == 0)
                {
                    echo "$Value is numeric, and even";
                }
                else
                {
                    echo "$Value is numeric, but not even";
                }
            }
            else
            {
                echo "$Value is not numeric";
            }
}
