如何优化以下PHP代码？

<?php

if(strlen($_POST['myName']) < 2 || isNumeric($_POST['myName']))
{
    echo "Please fill in your name!";
    exit();
}

if(!is_numeric($_POST['myAge']) || strlen($_POST['myAge'] < 1))
{
    echo "Please enter only digits!";
    exit();
}

if(strlen($_POST['myRes']) < 2 || isNumeric($_POST['myRes']))
{
    echo "Please enter something!";
    exit();
}

echo "Hi " . $_POST['myName'] . "! you are " . $_POST['myAge'] . " years old and live in " . $_POST['myRes'] . "? Nice to meet you!";

?> 

如果我想测试100个输入怎么办？如何以最佳方式进行测试？
