I can see my function or should i say more correctly weedpackets age calculator has been put to some use.

I have a few questions however..

echo '<PRE>'; print_r(func_get_args ()); echo '</PRE>'; 

😕 whats this actually trying to acheive

Also where is this variable coming from $get_age?

There is a return for a reason

return $age; 
print $age; 

Once a function returns a result the function has ended thus making the print $age useless.

Also

//your putting the arguments in the wrong way
checkCurAge($month,$day,$year);

If you cannot tell variables are named according what they are used for

function checkCurAge($year,$month,$day='') { 

To use this function the way it was intended here is an implementation

<?php

function checkCurAge($year,$month,$day='') {

  $day=(empty($day))?'1':$day;

  list($this_year, $this_month, $this_day) = explode(' ',date('Y n j'));
  $age = $this_year - $year;

  if ($month>$this_month||($this_month==$month&&$this_day<$day)) {
    $age--;
  }

  return $age;

}

$month = '5';
$day='12';
$year='1987';

echo checkCurAge($year,$month,$day);
?>   

Hope that helps

hmm... $get_age does not exist, and it would be good if you stated what exactly you are trying to do.

Ignore get age. I am pulling it from an array above that. I just manually set the $day month and year with a birthdate. Just to get the script working off the bat.

Sorry about all the errors. I'm just now getting into some higher level stuff other than if and echo heh. And before i saw your post i did some reading on some of those functions. For some reason i looked right over return the other day and i just read up on it now. Thank you..

Let me make some changes to the script and see what happens.

function checkCurAge($year,$month,$day='') {


 $day=(empty($day))?'1':$day;

 list($this_year, $this_month, $this_day) = explode(' ',date('Y n j'));
 $age = $this_year - $year;
 echo $year;
if($this_month<=$month && ($this_month==$month || $this_day<$day)) {

$age--;
 }

 return $age;
}

$month = '5';
$day='12';
$year='1987';

checkCurAge($year,$month,$day);

Basically when i use this script. Exactly. It just gives me the result of 1987 which is the year. Not an actual date.

Sorry, trying to learn and accomplish this all at the same time.

No you dont need to its an example of how it should be used it does what is intended return the age of someone.

Now you could instead of echo'ing it out assign a variable to it so

$userAge = checkCurAge($year,$month,$day);

and use the $userAge later on within the script eventually it will be echo'ed out to the browser unless it is used for some other purpose.

Becuase then it just echo's the date month and year.

Ok it shouldnt be echo'ing out the day, month, year if its doing that you have obviously done something wrong. It should be echo'in out an age.

[planetsim]

That would be because of this line

 echo $year;

Within your function take it out. when you return a result from a function thus

return $age

The function will not output anything to the screen. But rather allow something like an echo like i showed in a previous post the $age variable from the function however you can also use a variable to the function like so

$userAge=checkCurAge($year,$month,$day);

And later on use the $userAge within the script.
