如何取決於一個數組值在另一個數組值

Question

我有兩個陣列， 即

Array ( 
[0] => Sony Xperia Modern Silver 
[1] => Sony Xperia C Purple 
[2] => Sony Xperia C3 Starry Black 
[3] => Sony Xperia C3 Snow White 
[4] => Sony Xperia C3 Fresh Mint 
[5] => Sony Xperia C4 Dual Mint 
[6] => Sony Xperia C4 Dual White 
[7] => Sony Xperia C4 Dual Black); 

And 

Array ( 
[0] => 40 
[1] => 40 
[2] => 60 
[3] => 40 
[4] => 40 
[5] => 80 
[6] => 80 
[7] => 100); 

所以在對NAME的和在％評論第二陣列這種情況下第一陣列， 怎麼我的第一個數組值取決於第二個數組條件，因爲當我們給if條件（review> = 60）時，我們需要數據（即產品名稱）。 在此，我需要的輸出是相關的名稱是取它的評論是大於或等於60和記錄按降序排列（記錄按降序排列取決於perticuler的評論）

Answer 1

<? 
$ProductName[]=Array ( 
[0] => Sony Xperia Modern Silver 
[1] => Sony Xperia C Purple 
[2] => Sony Xperia C3 Starry Black 
[3] => Sony Xperia C3 Snow White 
[4] => Sony Xperia C3 Fresh Mint 
[5] => Sony Xperia C4 Dual Mint 
[6] => Sony Xperia C4 Dual White 
[7] => Sony Xperia C4 Dual Black); 

And 

$Reviews[]=Array ( 
[0] => 40 
[1] => 40 
[2] => 60 
[3] => 40 
[4] => 40 
[5] => 80 
[6] => 80 
[7] => 100); 

$j=sizeof($ProductName); 

for($i=$j;$i>0;$i--) //For descending order 
{ 
    if($Reviews[$i]>=60) 
    { 
     echo $ProductName[$i]."<br>"; 
    } 
} 
?>
