預加載函數的數組值

Question

我不知道如果我正確地做到這一點，用函數defaultcoindload（）預加載硬幣的數組值。

defaultcoindload(); 
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*/ 

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."; 

而且是它甚至法律要做到這一點：

function getselection($selection,$price) 
{ 

具有原始功能defaultcoinload（）內其他功能或多種功能，我認爲它是隻需要一點點澄清，謝謝，不要燃燒。

看起來很好。這些陳述的順序可能令人困惑？大多數工程師會在調用函數聲明之前編寫函數聲明（你有它周圍的其他方法。）

兩件事情我看到的關注：

一個是任務分配時，它看起來像一個平等的比較更有意義：

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

另一種是$ money不是全球性的，因此在函數內分配它不會在其外面發生明顯的變化。通過在函數內部添加global $money來解決此問題。

總之，試試這個來代替：

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(); 

我已經刪除了很多東西，看起來像他們進行調試，但在此之後，你可以參考一下$錢。

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

我留給您識別和修復的其餘錯誤。
