如何以簡單的方式檢查5個變量是否相同或不相同?檢查多個值是否相等或使用php
這裏是我的示例代碼: -
$roster_1 = $_POST['roster_1'];
$roster_2 = $_POST['roster_2'];
$roster_3 = $_POST['roster_3'];
$roster_4 = $_POST['roster_4'];
$roster_5 = $_POST['roster_5'];
$checkcommon = array($roster_1 , $roster_2 , $roster_3 , $roster_4 , $roster_5);
if(array_sum($checkcommon) == count($checkcommon))
{
$errormsg = "All the same";
}
else
{
$errormsg = "not the same";
}
是否有任何人誰可以幫我...
'if(count(array_unique($ checkcommon))== 1){echo「all values are same」;}' –
