Hi
I try to use Function and Instead of useing global $var I try to use something like function($var)
Here is my code

test.php
////////////
<?
$var = 'Hi';

function load($var)
{
  echo $var;
}
?>

When try to see the page I'm getting that worning:
Warning: Missing argument 1 for load()......

Before I used something like this:

////////
<?
$var = "hi";
function load()
{
  global $var;
  echo $var;
}
?>

and it works.

Can anyone please tell me whats wrong with my first example (test.php)

Thanks

The purpose of a function is to do a certain function at the time its called. like the following function:

function load(){
echo "i like this";
}

You put this function in your header or on top of the page and then you can call it down anywhere in your code and it'd echo "i like this."

However, functions can have arguments. so something like

function load($var1, $var2){
echo $var1;
echo $var2;
}

to use this you can define $var1 and $var2 in your page down the line and use it this way:

$var1 = "this is Variable 1";
$var2 = "this is variable 2";

load($var1, $var2);

Now you don't have to use the same name for the variables in the page as you used in the function it could be:

$age1 = "my age is 1";
$age2 = "my age is 2";

load ($age1, $age2);

and that'd give you the same result.
