I want to write a php object in a text file. The php object is like that
我想在文本文件中编写一个 php 对象。php 对象就是这样
$obj = new stdClass();
$obj->name = "My Name";
$obj->birthdate = "YYYY-MM-DD";
$obj->position = "My position";
I want to write this $obj in a text file. The text file is located in this path
我想把这个 $obj 写在一个文本文件中。文本文件位于此路径中
$filePath = getcwd().DIRECTORY_SEPARATOR."note".DIRECTORY_SEPARATOR."notice.txt"
I want a simple way to write this object into the text file and want to read the file to get the properties as I defined. Please help me.
我想要一种将此对象写入文本文件的简单方法，并希望读取该文件以获取我定义的属性。请帮我。

$obj = new stdClass();
$obj->name = "My Name";
$obj->birthdate = "YYYY-MM-DD";
$obj->position = "My position";
$objData = serialize( $obj);
$filePath = getcwd().DIRECTORY_SEPARATOR."note".DIRECTORY_SEPARATOR."notice.txt";
if (is_writable($filePath)) {
$fp = fopen($filePath, "w");
fwrite($fp, $objData);
fclose($fp);
}

要读取文本文件以获取您定义的属性...
$filePath = getcwd().DIRECTORY_SEPARATOR."note".DIRECTORY_SEPARATOR."notice.txt";
if (file_exists($filePath)){
$objData = file_get_contents($filePath);
$obj = unserialize($objData);
if (!empty($obj)){
$name = $obj->name;
$birthdate = $obj->birthdate;
$position = $obj->position;
}

You can use serialize()before saving it to the file and then unserialize()to get the whole $objavailable to you:
您可以serialize()在将其保存到文件之前使用，然后unserialize()让整个文件$obj可供您使用：
$obj = new stdClass();
$obj->name = "My Name";
$obj->birthdate = "YYYY-MM-DD";
$obj->position = "My position";
$objtext = serialize($obj);
//write to file
Then later you can unserialize():
然后你可以反序列化（）：
$obj = unserialize(file_get_contents($file));
echo $obj->birthdate;//YYYY-MM-DD
