Adding elements to array?
提问by panthro
How can I add more than one element to my keyed array?
如何将多个元素添加到我的键控数组中？
array_add($myArray, 'key', 'a');
array_add($myArray, 'key-2', 'b');
Is there a better way?
有没有更好的办法？
回答by Antonio Carlos Ribeiro
I prefer:
我更喜欢：
$myArray['key'] = 'a';
$myArray['key-2'] = 'b';
But this is not really better, because you're not adding more than one in a single command.
但这并不是更好，因为您不会在单个命令中添加多个。
And if you really need to add multiple, you can always create a helper:
如果你真的需要添加多个，你总是可以创建一个助手：
function array_add_multiple($array, $items)
{
foreach($items as $key => $value)
{
$array = array_add($items, $key, $value);
}
return $array;
}
And use it as
并将其用作
$array = array_add_multiple($array, ['key' => 'a', 'key-2' => 'b']);
or, if you're not using PHP 5.4:
或者，如果您没有使用 PHP 5.4：
$array = array_add_multiple($array, array('key' => 'a', 'key-2' => 'b'));

There is no need for any other custom function because in PHPthere is a built-in function for this and it's array_mergeand you can use it like this:
不需要任何其他自定义函数，因为它PHP有一个内置函数，它是array_merge，您可以像这样使用它：
$myArray = array('one' => 'TheOne', 'two' => 'TheTwo');
$array = array_merge($myArray, array('three' => 'TheThree', 'four' => 'TheFour'));
print_r($array);
Output:
输出：
Array
(
[one] => TheOne
[two] => TheTwo
[three] => TheThree
[four] => TheFour
)
You can also use this:
你也可以使用这个：
$myArray1 = array('one' => 'TheOne', 'two' => 'TheTwo');
$myArray2 = array('three' => 'TheThree', 'four' => 'TheFour');;
$array = $myArray1 + $myArray2;
print_r($array);
Output:
输出：
Array
(
[one] => TheOne
[two] => TheTwo
[three] => TheThree
[four] => TheFour
)

My custom "on the fly" method:
我的自定义“即时”方法：
function add_to_array($key_value)
{
$arr = [];
foreach ($key_value as $key => $value) {
$arr[] = [$key=>$value];
}
return $arr;
}
dd(add_to_array(["hello"=>"from this array","and"=>"one more time","what"=>"do you think?"]));
