Question

这是我的输出：我使用更多的foreach循环，将不同的条件和值放入相同的数组名$returnVal[]=

EX：

foreach($val1 as $vals)
{
      $returnVal[]=$vals;
}




foreach($val2 as $vals)
  {
      $returnVal[]=$vals;
  }



 foreach($val3 as $vals)
  {
      $returnVal[]=$vals;
   }



 foreach($val4 as $vals)
   {
      $returnVal[]=$vals;
   } `

我得到输出：

 Array

        [0] => Array
            (
                [0] => 39705--COLUMBUS--LOWNDES--MS

                [2] =>  39710--COLUMBUS--LOWNDES--MS
                [3] =>  39701--COLUMBUS--LOWNDES--MS

                            )

                    )

                [2] => 57038--JEFFERSON--UNION--SD
            )

        [3] => 57049--NORTH SIOUX CITY--UNION--SD

我的问题：删除重复的值并合并到一个级别

Answer 1

如果结果数组中不存在推送元素，这将避免重复的条目。请尝试下面的代码，

$returnVal = [];
foreach($val1 as $vals)
{
    if (!in_array($vals, $returnVal)) {
        $returnVal[]=$vals;
    }

} ..etc and so on
