怎么才能把 只有 一个值的数组合并到下一个数组

Answer 1

例如把
array(
[0] => Array
  (
  [title22] => 噩噩噩噩噩噩噩噩噩噩噩噼噼啪啪
  )  [1] => Array
  (
  [id] => 479
  [questionId] => 0
  [projectId] => 11
  [title] => 11
  [optionA] => 对
  [optionB] => 11
  [optionC] => 11
  [optionD] => 11
  [part] => 4

  [type] => 1
  [forbid] => 0
  [] => 11
  [rightAnswer] => A
  [info] => 11111
  [aid] => 49
  ))改成
array(
  [1] => Array
  (
  [title22] => 噩噩噩噩噩噩噩噩噩噩噩噼噼啪啪
  [id] => 479
  [questionId] => 0

将就吧...简单的for.$TestArray=array(array('0'=>'a'),array('1'=>'1122','2'=>'333'),array('2'=>'b'),array('3'=>'3344','44'=>'2222'),
array('4'=>'c'),array('5'=>'5566','4'=>'334343'),array('444'=>'test','aaa'=>'cccc'),array('eee'=>'3242','94js'=>'222'));/**

function Marray($Array){
$NewArray=array();
for ($i=0;$i<count($Array);$i++){
if (count($Array[$i])==1){
$NewArray[]=array_merge($Array[$i],$Array[$i+1]);
}else{
if (count($Array[$i-1])!==1){
$NewArray[]=$Array[$i];
}
}
}
return $NewArray;
}
//测试结果
$Test=Marray($TestArray);
print_r($Test);/**

谢谢 我 写了一个 更简单的方法 for($i=0;$i<count($a)+1;$i++) {
    if($a[$i][id]=="") {
        $a[$i+1] += $a[$i];
unset($a[$i]);
    }
}print_r($a);/*测试结果Array
