如何将数组存储在文件中以便稍后使用PHP作为数组进行访问？

I just want to quickly store an array which I get from a remote API, so that i can mess around with it on a local host.

我只想快速存储一个从远程API获取的数组，这样我就可以在本地主机上乱搞它。

So:

所以：

I currently have an array.
我目前有一个阵列。
I want to people to use the array without having to get it from the API.
我希望人们使用该数组，而无需从API中获取它。

There are no needs for efficiency etc here, this isnt for an actual site just for getting some sanitizing/formatting methods made etc

这里不需要效率等，这对于实际网站来说只是为了获得一些消毒/格式化方法等

Is there a function like store_array() or restore_arrray() ?!

有没有像store_array（）或restore_arrray（）这样的函数？

The best way to do this is JSON serializing. It is human readable and you'll get better performance (file is smaller and faster to load/save). The code is very easy. Just two functions

执行此操作的最佳方法是JSON序列化。它是人类可读的，你将获得更好的性能（文件更小，加载/保存更快）。代码非常简单。只是两个功能

json_encode
json_encode
json_decode
json_decode

Example code:

示例代码：

$arr1 = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
file_put_contents("array.json",json_encode($arr1));
# array.json => {"a":1,"b":2,"c":3,"d":4,"e":5}
$arr2 = json_decode(file_get_contents('array.json'), true);
$arr1 === $arr2 # => true

You can write your own store_array and restore_array functions easily with this example.

您可以使用此示例轻松编写自己的store_array和restore_array函数。

For speed comparison see benchmark originally from Preferred method to store PHP arrays (json_encode vs serialize).

对于速度比较，请参阅最初从Preferred方法存储PHP数组的基准（json_encode vs serialize）。

If you don't need the dump file to be human-readable, you can just serialize() the array.

如果您不需要转储文件是人类可读的，则可以序列化（）数组。

storing:

存储：

file_put_contents('yourfile.bin', serialize($array));

retrieving:

检索：

$array = unserialize(file_get_contents('yourfile.bin'));

#3

Use serialize and unserialize

使用序列化和反序列化

// storing
$file = '/tmp/out.data';
file_put_contents($file, serialize($mydata)); // $mydata is the response from your remote API

// retreiving
$var = unserialize(file_get_contents($file));

Or another, hacky way:

或另一种黑客方式：

var_export() does exactly what you want, it will take any kind of variable, and store it in a representation that the PHP parser can read back. You can combine it with file_put_contents to store it on disk, and use file_get_contents and eval to read it back.

var_export（）完全符合您的要求，它将采用任何类型的变量，并将其存储在PHP解析器可以读回的表示中。您可以将它与file_put_contents结合使用以将其存储在磁盘上，并使用file_get_contents和eval将其读回。

// storing
$file = '/tmp/out.php';
file_put_contents($file, var_export($var, true));

// retrieving
eval('$myvar = ' . file_get_contents($file) . ';');

#4

You can use serialize to make it into a string to write to file, and the accompanying unserialize to return it to an array structure.

您可以使用serialize将其转换为要写入文件的字符串，并使用随附的unserialize将其返回到数组结构。

I'd suggest using a language independent structure though, such as JSON. This will allow you to load the files using different languages than PHP, in case there's a chance of that later. json_encode to store it and json_decode($str, true) to return it.

我建议使用与语言无关的结构，例如JSON。这将允许您使用与PHP不同的语言加载文件，以防以后有可能。 json_encode存储它和json_decode（$ str，true）返回它。

#5

Use php's serialze:

使用php的序列号：

file_put_contents("myFile",serialize($myArray));

#6

Another fast way not mentioned here:

另一个没有提到的快速方法：

That way add header with <?php start tag, name of variable \$my_array = with escaped \$ and footer ?> end tag.

这样就添加了带有<？php开始标记的头部，变量名称为$ $ my_array =带有转义的\ $和页脚？>结束标记。

Now can use include() like any other valid php script.

现在可以像任何其他有效的PHP脚本一样使用include（）。

// storing
$file = '/tmp/out.php';
file_put_contents($file, "<?php\n\$my_array = ".var_export($var, true).";\n?>");

// retrieving as included script
include($file);

//testing
print_r($my_array);

out.php will look like this

out.php看起来像这样

<?php
  $my_array = array (
    'a'=>1,
    'b'=>2,
    'c'=>3,
    'd'=>4,
    'e'=>5
  );
?>
