php - 根据键合并相同的数组索引并构建一个新数组

Question

我正在尝试合并数组索引，例如
011,021,031, 012,022,032, 013,023,033, 014,024,034 。

$temp = array();
foreach($samplearray as $key => $val){
    foreach($val as $key1 => $val1){
       //what should logic here     
    }
}

样本数组

$samplearray = array ( "AA"  => array ( 0  => array ( "created by" => "011",
                                                "date" => "12-03-14",
                                                "time" => "12.00 pm"

Answer 1

其实它很简单。提示已经在标题中。array_merge()：

$newArray = array();
foreach ($samplearray as $key => $batch) {
    $newArray = array_merge($newArray, $batch);
}

要遵循这种特殊格式，您可以每次都移动它们，直到$samplearray用完为止。

例子：

$newArray = array();
while(true) {
    foreach ($samplearray as $key => &$batch) {
        $newArray[] = array_shift($batch); // shift each batch
    }

    if(empty($batch)) { // if it runs out, stop!
        break;
    }
}

Answer 2

试试这个代码

$temp = array();
foreach($samplearray as $key => $val){
   foreach($val as $key1 => $val1){
       $temp[] = $val1;
   }
