我有一个这样的数组(从数据库动态生成的数组(
$attr = array('color'=>array('red','pink','yello','white','black','light-yellow','maroon','neal'),"brand"=>array('nike','adidas','dg','puma','neaon'),"size"=>array(8,10,11,12,13,14,15));
我需要这样的结果
red-nike-8
red-nike-9
red-nike-10
red-nike-11
red-nike-12
red-nike-13
red-nike-14
red-nike-15
red-adidas-8
red-adidas-9
red-adidas-10
red-adidas-11
red-adidas-12
red-adidas-13
red-adidas-14
red-adidas-15
red-dg-8

下面是我的代码，这是静态的，但我需要开发来创建动态结构。
$attr_color = array('red','pink','yello','white','black','light-yellow','maroon','neal');
$attr_brand = array('nike','adidas','dg','puma','neaon');
$attr_size = array(8,10,11,12,13,14,15);
$array = array();
foreach ($attr_color as $key => $value_one)
{
foreach ($attr_brand as $key => $value_two)
{
foreach ($attr_size as $key => $value_three)
{
$array[] = array($value_one,$value_two,$value_three);
}
}
}
正如您在初始中提到的动态数组，考虑到它是一个包含多个子数组的深度二数组，如下面的代码所示。您可以在其中添加任何其他子数组，就像我添加其他数组一样。
$attr = [
[
'color1',
'color2',
'color3',
],
[
'brand1',
'brand2',
'brand3',
],
[
'size1',
'size2',
'size3',
],
[
'other1',
'other2',
'other3',
],
];
您必须像这样循环才能达到预期的结果。
function combinations($arrays, $i = 0) {
if (!isset($arrays[$i])) {
return [];
}
if ($i == count($arrays) - 1) {
return $arrays[$i];
}
// get combinations from subsequent arrays
$tmp = combinations($arrays, $i + 1);
$result = [];
// concat each array from tmp with each element from $arrays[$i]
foreach ($arrays[$i] as $v) {
foreach ($tmp as $t) {
$result[] = is_array($t) ?
array_merge([$v], $t) :
[$v, $t];
}
}
$finalArray = [];
foreach($result as $k => $val){
$finalArray[$k] = implode("-",$val);
}
return $finalArray;
}
$result = combinations($attr);
print_r($result);
最终结果如下。
