如何在php（laravel5）中创建多个数组？

Question

我想通过php（laravel5）创建多个数组。 有两个数组如下。

$tags=['en' =>[]];
$TAGS = ['test1','test2','test3',...]

我想在某些代码中将此数组作为返回值，如下所示：

return [
    'tags' => [
        'en' => [
            'test1' => 'test1',
            'test2' => 'test2',
            'test3' => 'test3',
            ...
        ]
    ]
]

我尝试了以下，但它没有用。

return [
    'tags' => [
        'en' => [
            foreach($TAGS as $TT)
                array_push($tags['en'], $TT);
        ]
    ]
]

还有其他方法吗？ 请你的建议。谢谢。

试试这样：

<?php
$mainArray = array("EN","IT","SP"....);
$returnArray = array();
foreach($mainArray as $key => $value){
    //Create the sub array here as you want it.
    $subArray = [
        "Test1" => "test1",
        "Test2" => "test2",
        "Test3" => "test3"
    ];        
    array_push($returnArray[$value],$subArray);
}

return $returnArray;
?>

试试这个 -

$json = array();
$langs = ['en','fr'];
$tags = ['test1','test2','test3'];
 foreach ($langs as $lang) {
    $json[$lang] = [];
    foreach ($tags as $tag) {
        $json[$lang][] = $tag;
    }
 }
return $json;
