usually a function has the following structure:
function <name> ( <arguments> ) { <code> }
of course you can put any whitspace inside:
function <name> ( <arguments> )
{
<code>
}
which makes it easy to read.
You can put anything you want inside a function, but you must know, that you
cannot directly access a variable, that is defined outside the function.
$name = "mOrP";
function print_name()
{
echo $name;
}
print_name();
will not work.
Then you must 'get' the global variables (like $name):
$name = "mOrP";
function print_name()
{
global $name;
echo $name;
}
print_name();
But it's better to work with the function arguments:
$name = "mOrP"
function print_name($name_arg)
{
echo $name_arg;
}
print_name($name);
notice, that there is no ";" behind the { ... } and the ( ... ) block in the
definition of the function.
Hope it helps,
mOrP.
