Question

您如何將兩個變量合並為一個foreach？

$variableOne
$variableTwo

foreach($? as $data)
{
    print data here from both variables
}

Answer 1

很簡單的伙伴：

$new_array = array_merge($variableOne, $variableTwo);
foreach($new_array as $data)
{
    print data here from both variables
}

Answer 2

如果這些變量不是數組，則可以嘗試

foreach(array($variableOne, $variableTwo) as $data){
  echo $data
}
