php5中的验证合法性的扩展
在PHP5.2中,可以通过内置的扩展过滤器去进行合法性的校验,例子如下:

1 验证是否email:
  email = "jason@example.com";
if (filter_var($email, FILTER_VALIDATE_EMAIL))
  {
  echo "Valid email address!"; }
  else
{
echo "Invalid email address!";

}


2 验证是否整数
  if (filter_var($age), FILTER_VALIDATE_INT, array('options' => array('min_range' => 13, 'max_range' => 100)))
{
  echo "Valid age!";
}
else
{
echo "Invalid age!";
}


3 跟正则表达式
   if (filter_var($age), FILTER_VALIDATE_INT, array('options' => array('min_range' => 13, 'max_range' => 100)))
  {
  echo "Valid age!";
  }
else
{
  echo "Invalid age!";

}
