Question

$original  = Array(
0=>"03A ",//first "03", substr("04w",0,2)=="03"
1=>"04a ",//first "04" of first "03"
2=>"05b ",
3=>"06c ",
4=>"07d ",

6=>"04w ",//second "04" of first "03"
7=>"05x ",
8=>"06y ",
9=>"07z ",

10=>"03B    ",//second "03"
11=>"04l    ",//first "04" of second "03" //substr("04w",0,2)=="03"
12=>"05m    ",
13=>"06n    ",
14=>"07o    ",

15=>"04l    ",//second "04" of second "03" //substr("04l",0,2)=="03"
16=>"05m    ",
17=>"06n    ",
18=>"07o    "
);

echo '<pre>';
print_r($original);
echo '</pre>';

function customize_array($original){
  $customized_array = array();
  foreach($original as $value) {
      if(substr($value,0,2) == "03") {
      // CHANGE 1
      $save = $value;// saved "03" yo put in child too.
      ++$r;//inc parent
      $j = 0; // child 
      $customized_array[$r][$j] =$value; // create parent
      } else {
      if (($j % 4) > 0) $value .= $value;
      // CHANGE 2
      else if ($j && $j % 4 == 0) $value = $save.$value;
      $customized_array[$r][floor($j / 4)] .= $value;
      ++$j;//inc child
      }
  }
  return $customized_array;
}

$display_list = customize_array($original);
echo '<pre>';
print_r($display_list);
echo '</pre>';

输出：

/*

    [1] => Array
        (
            [0] => 03A  04a 05b 05b 06c 06c 07d 07d

这里的每个人都有任何想法来获得这个结果。

Answer 1

两个变化：

foreach($original as $value) {
    if(substr($value,0,2) == "03") {
        // CHANGE 1
        $save = $value;
        ++$r;//inc parent
        $j = 0; // child 
        $move_level[$r][$j] =$value;
    } else {
        if (($j % 4) > 0) $value .= $value;
        // CHANGE 2
        else if ($j && $j % 4 == 0) $value = $save.$value;
        $move_level[$r][floor($j / 4)] .= $value;
        ++$j;//inc child
    }
}

Answer 2

您可以使用array_slice和implode执行此操作：

$a1 = array_slice($original, 0, 5);
$a2 = array_slice($original, 5, 4);
$a3 = array_slice($original, 10, 5);
$a4 = array_slice($original, 15, 4);

$output = new Array(
  new Array(implode("",$a1), implode("",$a2)), 
  new Array(implode("",$a3), implode("",$a4))
);

如果要为动态数组执行此操作，您应该能够在for循环中使用类似的代码

你可以做的是修剪前3个字符，如substr($val, 3);，然后经过03a。或者你想从数组索引0获取前3个字符并在索引1中过去/替换它？如果是这样的话：

$array[0] => Array
    (
        [0] => 03A04a05b05b06c06c07d07d //yes "03A" here 
        [1] => 04w05x05x06y06y07z07z // no "03A" here 
    )

$array[1] => Array
    (
        [0] => 03B04l05m05m06n06n07o07o //"03B" here 
        [1] => 04l05m05m06n06n07o07o // no "03B" here 
    )
$new_array = array();
foreach($array as $value)
{
   $first = substr($value[0], 0, 3);
   $new_array[] = array($value[0], $value[1]);
}

print_r($new_array);

结果：

Array
(
    [0] => Array
    (
        [0] => 03A04a05b05b06c06c07d07d //yes "03A" here 
        [1] => 03A04w05x05x06y06y07z07z //yes "03A" here 
    )

    [1] => Array
    (
        [0] => 03B04l05m05m06n06n07o07o //"03B" here 
        [1] => 03B04l05m05m06n06n07o07o//"03B" here 
    )

)

我确信有更好的方法，这是我认为的全球方式
