如果特定函数无法执行，PHP函数返回布尔值

Question

I have a PHP function which requires 2 arguments . The function calculates the number of days between that given 2 dates(arguments are given in MM/DD/YYYY format) . When I am passing invalid type of arguments PHP throws me an error . So my question is ... Is there a function or something like that which will catch that error (So that already PHP will not throw me an error) so I will be able to use that in my "if()" statments to see weather the function has been successfully executed ?

Answer 1

You should write your code but you can try something like this:

function diffDates($date1 , $date2)
{
  if(!isValidDate($date1) || !isValidDate($date2))
    return false;

 //Do something

 return true;
}

//Check if $date is in format: mm/dd/yy
function isValidDate($date)
{
 $temp = explode("/" , $date);
 if(!is_array($temp))
   return false;
 return checkdate($temp[0] , $temp[1] , $temp[2]);
}
