PHP Array saved to Text file
提问by coffeemonitor
I've saved a response from an outside server to a text file, so I don't need to keep running connection requests. Instead, perhaps I can use the text file for my manipulation purposes, until I'm read for re-connecting again. (also, my connection requests are limited to this outside server)
我已将来自外部服务器的响应保存到文本文件，因此我不需要继续运行连接请求。相反，也许我可以将文本文件用于我的操作目的，直到我再次阅读以重新连接。（另外，我的连接请求仅限于这个外部服务器）
Here is what I've saved to a text file:
这是我保存到文本文件中的内容：
records.txt
记录.txt
Array
(
[0] => stdClass Object
(
[id] => 552
[date_created] => 2012-02-23 10:30:56
[date_modified] => 2012-03-09 18:55:26
[date_deleted] => 2012-03-09 18:55:26
[first_name] => Test
[middle_name] =>
[last_name] => Test
[home_phone] => (123) 123-1234
[email] => [email protected]
)
[1] => stdClass Object
(
[id] => 553
[date_created] => 2012-02-23 10:30:56
[date_modified] => 2012-03-09 18:55:26
[date_deleted] => 2012-03-09 18:55:26
[first_name] => Test
[middle_name] =>
[last_name] => Test
[home_phone] => (325) 558-1234
[email] => [email protected]
)
)
There's actually more in the Array, but I'm sure 2 are fine.
Array 中实际上还有更多，但我确定 2 没问题。
Since this is a text file, and I want to pretend this is the actual outside server (sending me the same info), how do I make it a real array again?
由于这是一个文本文件，并且我想假装这是实际的外部服务器（向我发送相同的信息），我如何再次使其成为真正的数组？
I know I need to open the file first:
我知道我需要先打开文件：
<?php
$fp = fopen('records.txt', "r"); // open the file
$theData = fread($fh, filesize('records.txt'));
fclose($fh);
echo $theData;
?>
So far $theDatais a string value. Is there a way to convert it back to the Array it originally came in as?
到目前为止$theData是一个字符串值。有没有办法将它转换回它最初作为的数组？

Better serialize and save to file, then unserialize back to array.
更好地序列化并保存到文件，然后反序列化回数组。
// serialize your input array (say $array)
$serializedData = serialize($array);
// save serialized data in a text file
file_put_contents('your_file_name.txt', $serializedData);
// at a later point, you can convert it back to array like:
$recoveredData = file_get_contents('your_file_name.txt');
// unserializing to get actual array
$recoveredArray = unserialize($recoveredData);
// you can print your array like
print_r($recoveredArray);

You shouldn't have saved it in print_rformat then.
print_r那时你不应该以格式保存它。
Use either:
使用：
That makes it simple to decode the file back into an array.
这使得将文件解码回数组变得简单。
Albeit there is a print_r decoder. But that should be the last resort, only if you cannot affect the input data (which you can!).
尽管有一个print_r 解码器。但这应该是最后的手段，前提是您不能影响输入数据（您可以！）。
回答by NullPoiиteя
You could serializethe array before writing it as text to a file. Then you can read the data back out of the file unserializewill turn it back into an array.
您可以serialize先将数组作为文本写入文件。然后您可以从文件中读取数据，unserialize将其重新转换为数组。

JSON Version
JSON 版本
$json_data = json_encode($the_array);
file_put_contents("records.txt", $json_data);
// Recovering
$the_data = file_get_contents("records.txt");
$the_array = json_decode($the_data);
