Pre-loading array values into a function

I am not sure if I am doing this correctly,pre-loading my array values for coins with the function defaultcoindload();

defaultcoindload();
function defaultcoindload()
{
/*Have the coin loads up 开发者_Go百科to a maximum of a 1.00 dollar in value:
An associative array-ID key is associated with  value(ID is Nickels with value of 20).
$money = array("Nickels"=>20, "Dimes"=>10, "Quarters"=>10);
The array code for $money above  is  the same as the array code below,
with the difference being the structure and the ID keys can be accessed in a script*/

if ($money < 1.00)
{
echo "money";
}
else if($money = $insertcoins[$selection])
{
echo "$selection";
}


 $money['Nickels'] = "20";
 $money['Dimes'] = "10";
 $money['Quarters'] = "10";
 echo "The value of Nickels is " . $money['Nickels'] ." cents.";

Furthermore is it even legal to do this:

function getselection($selection,$price)
{

Have another function or multiple functions inside of the original function defaultcoinload(), I think it is just need a little clarification, thank you, for not flaming.

It looks fine. Perhaps the order of the statements is confusing? Most engineers would write the function declaration before calling it. (You have it the other way around.)

Two things I see of concern:

One is an assignment where it looks like an equality comparison makes more sense:

if ($money == $insertcoins[$selection])

The other is that $money isn't global, so assigning it within the function won't make a visible change outside it. Fix this by adding global $money inside the function.

In summary, try this instead:

function defaultcoindload()
{
    /* Have the coin loads up to a maximum of a 1.00 dollar in value:
     * An associative array-ID key is associated with  value (ID is Nickels with value of 20).
     * $money = array("Nickels"=>20, "Dimes"=>10, "Quarters"=>10);
     * The array code for $money above is the same as the array code below,
     * with the difference being the structure and the ID keys can be accessed in a script
     */
    global $money;

    $money['Nickels'] = 20;
    $money['Dimes']   = 10;
    $money['Quarters'] = 4;
    echo "The value of Nickels is " . $money['Nickels'] ." cents.";
}

defaultcoindload();

I've removed a lot of things which look like they were for debugging, but after this, you can reference $money.

print_r($money);  // show all the money

The remaining bugs I leave for you to identify and fix.
