PHP降序功能

Question

我想把「for」函數的遞減結果。 例子：我有這樣的PHP代碼：

<?php 
$field[1] = "Field 1"; // 1 
$field[2] = "Field 2"; // 2 
$field[3] = "Field 3"; // 3 
$field[4] = "Field 4"; // 4 
$field[5] = "Field 5"; // 5 
$field[6] = "Field 6"; // 6 
$field[7] = "Field 7"; // 7 
$field[8] = "Field 8"; // 8 
$field[9] = "Field 9"; // 9 
$field[10] = "Field 10"; // 10 

$i = "10"; 

for ($n=1 ; $n < $i ; $n++) { 

echo $field[$n]; 

} 
?> 

顯示：

Field 1 
Field 2 
Field 3 
Field 4 
Field 5 
Field 6 
Field 7 
Field 8 
Field 9 
Field 10 

我該怎麼做才能顯示降？像這樣：

Field 10 
Field 9 
Field 8 
Field 7 
Field 6 
Field 5 
Field 4 
Field 3 
Field 2 
Field 1 

任何解決方案？ 提前致謝！

Answer 1

foreach(array_reverse(range(1, 10), TRUE) as $key => $value) 
{ 
    echo 'Field ' . $value; 
} 

開始從0

Answer 2

查找array_reverse（http://php.net/manual/en/function.array-reverse.php）

我GoogleGuy同意，你也應該改變你對語句的foreach

<?php 
$field[1] = "Field 1"; // 1 
$field[2] = "Field 2"; // 2 
$field[3] = "Field 3"; // 3 
$field[4] = "Field 4"; // 4 
$field[5] = "Field 5"; // 5 
$field[6] = "Field 6"; // 6 
$field[7] = "Field 7"; // 7 
$field[8] = "Field 8"; // 8 
$field[9] = "Field 9"; // 9 
$field[10] = "Field 10"; // 10 

$reversed = array_reverse($field); 

foreach ($reversed AS $element) 

echo $element; 

} 
?> 

Answer 3

for ($n=$i; $n>=1; $n--) { 
    echo $field[$n]; 
} 

Answer 4

不要使用循環遍歷數組。 PHP有一個可愛的foreach構造，它可以做得更好，而且更方便。

foreach (array_reverse($field) as $value) { 
    echo "$value\n"; 
}
