Question

如何将两个变量合并为一个foreach？

$variableOne
$variableTwo

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

Answer 1

非常简单的伙伴：

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

Answer 2

如果这些变量不是数组，您可以尝试

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