Question

我想合并3个数组。

我的第一个是：

Array ( [0] => Leaves-19 [1] => Shifts-1 [2] => Shifts-1 [3] => Shifts-1 [4] => Shifts-1 [5] => Shifts-1 [6] => Leaves-19 [7] => Leaves-19 [8] => Shifts-1 [9] => Shifts-1 [10] => Shifts-1 [11] => Shifts-1 [12] => Shifts-1 [13] => Leaves-19 [14] => Leaves-19 [15] => Shifts-1 [16] => Shifts-1 [17] => Shifts-1 [18] => Shifts-1 [19] => Shifts-1 [20] => Leaves-19 [21] => Leaves-19 [22] => Shifts-1 [23] => Shifts-1 [24] => Shifts-1 [25] => Shifts-1 [26] => Shifts-1 [27] => Leaves-19 [28] => Leaves-19 [29] => Shifts-1 [30] => Shifts-1 [31] => Shifts-1 [32] => Shifts-1 [33] => Shifts-1 [34] => Leaves-19 [35] => Leaves-19 [36] => Shifts-1 [37] => Shifts-1 [38] => Shifts-1 [39] => Shifts-1 [40] => Shifts-1 [41] => Leaves-19 )

我的第二个是：

Array ( [0] => 2013-04-28 [1] => 2013-04-29 [2] => 2013-04-30 [3] => 2013-05-01 [4] => 2013-05-02 [5] => 2013-05-03 [6] => 2013-05-04 )

第三个是：

Array ( [0] => 13 [1] => 10 [2] => 12 [3] => 9 [4] => 14 [5] => 11 )

我想：

2013-04-28 / 13 / Leaves-19
2013-04-29 / 13 / Shifts-1
2013-04-30 / 13 / Shifts-1
2013-05-01 / 13 / Shifts-1
2013-05-02 / 13 / Shifts-1
2013-05-03 / 13 / Shifts-1
2013-05-04 / 13 / Leaves-19
2013-04-28 / 10 / Leaves-19
2013-04-29 / 10 / Shifts-1
2013-04-30 / 10 / Shifts-1
2013-05-01 / 10 / Shifts-1
2013-05-02 / 10 / Shifts-1
2013-05-03 / 10 / Shifts-1
2013-05-04 / 10 / Leaves-19
...

Thansk寻求帮助。

我尝试了什么：

echo print_r($_POST['dayType'])."<hr />";
echo print_r($_POST['dayArr'])."<hr />";
echo print_r($_POST['userArr'])."<hr />";

//echo count($_POST['dayType'])." --- ".count($_POST['dayArr'])." --- ".count($_POST['userArr']);

// 2013-05-04 / 13 / Leaves-19
$loopNb1 = count($_POST['dayType']);
$loopNb2 = count($_POST['dayType'])/7;

for($a=0; $a<$loopNb1; $a++) {
    echo $_POST['dayType'][$a]."<br />";
}

echo "<hr />";

for($b=0; $b<$loopNb2; $b++) {
    echo $_POST['userArr'][1]."<br />";
}

Answer 1

了解主意 -

//Your array
$a = array(1, 2, 3, 4, 5, 6,7,8);
$b = array("one", "two", "three", "four", "five",'123', 'asdfsadf');
$c = array("uno", "dos", "tres", "cuatro", "cinco", 'jina');


function myFunc($first, $second, $third) {
    if (!empty($first) && !empty($second) && !empty($second)) {
        return $first . '/' . $second . '/'. $third;
    }
}

// get the lowest size of array
$minimumSize = min(count($a), count($b), count($c));

//modify array in terms of lowest size
$firstArray = array_slice($a, 0, $minimumSize);
$secondArray = array_slice($b, 0, $minimumSize);
$thirdArray = array_slice($c, 0, $minimumSize);

$d = array_map('myFunc', $firstArray, $secondArray, $thirdArray);

Answer 2

第一个/第二个/第三个数组与您粘贴的数组相同（相同顺序）。

$datesCount        = count( $secondArray );
$firstArrayLength  = count( $firstArray );
$thirdArrayLength  = count( $thirdArray );

for( $i=0 ; $i < $thirdArrayLength ; $i++ )
{
    $currentThirdArrayValue = $thirdArray[$i];

    for( $inner=0, $firstArrayIndex=0 ; $inner < $datesCount ; $inner++, $firstArrayIndex++ )
    {
        if( $firstArrayIndex == $firstArrayLength )
                $firstArrayIndex = 0;

        echo "{$secondArray[$inner]} / {$currentThirdArrayValue} / {$firstArray[$firstArrayIndex]}<br/>\n";
    }
}

会给你：

2013-04-28 / 13 / Leaves-19<br/>
2013-04-29 / 13 / Shifts-1<br/>
2013-04-30 / 13 / Shifts-1<br/>
2013-05-01 / 13 / Shifts-1<br/>
2013-05-02 / 13 / Shifts-1<br/>
2013-05-03 / 13 / Shifts-1<br/>
2013-05-04 / 13 / Leaves-19<br/>
2013-04-28 / 10 / Leaves-19<br/>
2013-04-29 / 10 / Shifts-1<br/>
2013-04-30 / 10 / Shifts-1<br/>
2013-05-01 / 10 / Shifts-1<br/>
2013-05-02 / 10 / Shifts-1<br/>
2013-05-03 / 10 / Shifts-1<br/>
2013-05-04 / 10 / Leaves-19<br/>

等......结束于：

2013-05-01 / 11 / Shifts-1<br/>
2013-05-02 / 11 / Shifts-1<br/>
2013-05-03 / 11 / Shifts-1<br/>
2013-05-04 / 11 / Leaves-19<br/>

Answer 3

如果你想要这3个阵列的所有组合（称为$ first，$ second，$ third），你可以这样做：

foreach($first as $a){
 foreach($second as $b){
   foreach($third as $c{
     //do whatever you want with $a,$b,$c
     echo "$a/$b/$c";
   }
 }  
}

合并多个Array（）取决于循环和数字
