顯示變量恰好是其他變量的3倍

Question

$first = "Text 1" 
$second = "Text 2" 
$third = "Text 3" 
$fourth = "Text 4" 
$fifth = "Text 5" 

我想創建一個函數，它顯示$ second和$第四次的次數比其他變量多3倍。

如何做到這一點？

Answer 1

$arr = array($first, $second, $second, $second, $third, $fourth, $fourth, $fourth, $fifth); 
$elem = $arr[array_rand($arr)]; 

這會從數字到您的變量
