Question

有没有办法将多个数组与相同数量的项目组合在一起？请参阅下面的4个阵列，里面有5个项目：

$type = array('Type 1','Type 2','Type 3',' Type 4','Type 5');
$desc = array('Description 1','Description 2','Description 3','Description 4','Description 5');
$brand = array('Brand 1','Brand 2','Brand 3','Brand 4','Brand 5');
$model = array('Model 1','Model 2','Model 3','Model 4','Model 5');

预期结果：

[0] => Array
    (
        [0] => Type 1
        [1] => Description 1
        [2] => Brand 1
        [3] => Model 1
    )

[1] => Array
    (
        [0] => Type 2
        [1] => Description 2
        [2] => Brand 2
        [3] => Model 2
    )

[2] => Array
    (
        [0] => Type 3
        [1] => Description 3
        [2] => Brand 3
        [3] => Model 3
    )

[3] => Array
    (
        [0] => Type 4
        [1] => Description 4
        [2] => Brand 4
        [3] => Model 4
    )

[4] => Array
    (
        [0] => Type 5
        [1] => Description 5
        [2] => Brand 5
        [3] => Model 5
    )

我不是PHP专家，请帮帮我:)。

谢谢。

Answer 1

试试这段代码：

$type = array('Type 1','Type 2','Type 3',' Type 4','Type 5');
$desc = array('Description 1','Description 2','Description 3','Description 4','Description 5');
$brand = array('Brand 1','Brand 2','Brand 3','Brand 4','Brand 5');
$model = array('Model 1','Model 2','Model 3','Model 4','Model 5');

$result = array();
foreach($type as $key=>$val){ // Loop though one array
    $val2 = $desc[$key]; 
    $val3 = $brand[$key];
    $val4 = $model[$key]; 
    $result[$key] =array($val,$val2, $val3,$val4);
}

print_r($result);

Answer 2

通过任何数组进行简单循环，使用该数组的键获取其数组数据并创建新数组

$type = array('Type 1','Type 2','Type 3',' Type 4','Type 5');
$desc = array('Description 1','Description 2','Description 3','Description 4','Description 5');
$brand = array('Brand 1','Brand 2','Brand 3','Brand 4','Brand 5');
$model = array('Model 1','Model 2','Model 3','Model 4','Model 5');

foreach($type as $key=>$type_val){ // Loop though one array
    $desc_val = $desc[$key] ?? ""; 
    $brand_val = $brand[$key] ?? "";
    $model_val = $model[$key] ?? ""; 
    $result[$key] = array($type_val,$desc_val,$brand_val,$model_val); // combine 
}

print_r($result);

注意： ??仅适用于PHP 7 +旧版本更改$desc[$key] ?? ""至isset($desc[$key]) ? $desc[$key] : ""

Answer 3

这是完美且经过测试的代码：

<?php
$type = array('Type 1','Type 2','Type 3',' Type 4','Type 5');
$desc = array('Description 1','Description 2','Description 3','Description 4','Description 5');
$brand = array('Brand 1','Brand 2','Brand 3','Brand 4','Brand 5');
$model = array('Model 1','Model 2','Model 3','Model 4','Model 5');

$result = array();

foreach ($type as $id => $key) {
    $result[$id] = array($key,$desc[$id],$brand[$id],$model[$id]);
}
echo "<pre>";print_r($result);
?>

Answer 4

array_map就是你真正需要的。

$type = array('Type 1','Type 2','Type 3',' Type 4','Type 5');
$desc = array('Description 1','Description 2','Description 3','Description 4','Description 5');
$brand = array('Brand 1','Brand 2','Brand 3','Brand 4','Brand 5');
$model = array('Model 1','Model 2','Model 3','Model 4','Model 5');

$res = array_map(function(...$val) {return $val;}, $type, $desc, $brand, $model);
print_r($res);
