我想知道如何将几个ARRAYS中的内容更改为新的ARRAYS。
我有这3个变量,每个都有一个ARRAY,让我们说第一个var是$number
并且它有这个数组:
Array
(
[0] => 1
[1] => 3
[2] => 9
)
第二个变量是$item
,它有:
Array
(
[0] => house
[1] => car
[2] => bike
)
第三个是$color
,它有:
Array
(
[0] => red
[1] => white
[2] => black
)
如何更改内容并创建如下的新数组:
Array
(
[0] => 1
[1] => house
[2] => red
)
Array
(
[0] => 3
[1] => car
[2] => white
)
Array
(
[0] => 9
[1] => bike
[2] => black
)

您可以使用array_map:
<?php
$number = [1,3,9];
$item = ['house','car','bike'];
$color = ['red','white','black'];
$res = array_map(null, $number, $item, $color);
print_r($res);
?>
将输出您想要的单个数组数组:
Array
(
[0] => Array
(
[0] => 1
[1] => house
[2] => red
)
[1] => Array
(
[0] => 3
[1] => car
[2] => white
)
[2] => Array
(
[0] => 9
[1] => bike
[2] => black
)
)

您可以使用array_map()创建一个回调函数,将每个值一起返回:
$result = array();
function merge_arrays($a,$b,$c){
return array($a,$b,$c);
}
$result = array_map("merge_arrays",$number,$item,$color);
