Use the file_get_contents() and file_put_contents() functions.
使用 file_get_contents() 和 file_put_contents() 函数。
Example:
例子：
$file = 'output.txt';
$buffer = 'my new line here';
if (file_exists($file)) {
$buffer = file_get_contents($file) . "\n" . $buffer;
}
$success = file_put_contents($file, $buffer);

If you want to create new file for everyday , you can create txt file with current date date('d-m-Y').".txt". so you can easily identify file by date.
如果您想为每天创建新文件，您可以创建具有当前日期的 txt 文件date('d-m-Y').".txt"。这样您就可以轻松地按日期识别文件。
try below code, i have made some change in code and test it.
尝试下面的代码，我对代码进行了一些更改并对其进行了测试。
<?php
$dateFile = date('d-m-Y').".txt";
$dataString = "name:" . $name . "age:" . $age."\n";
$fWrite = fopen($dateFile,"a");
$wrote = fwrite($fWrite, $dataString);
fclose($fWrite);
print "file created and written to";
?>
If file already created so you can store new record in new line by "\n", \n must be in "" quatoed.
如果文件已经创建，因此您可以通过 将新记录存储在新行中"\n"，\n 必须在 "" quatoed 中。

From the fopen docs:
从fopen 文档：
write:
写：
w Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length.If the file does not exist, attempt to create it.
w 只允许写；将文件指针放在文件的开头并将文件截断为零长度。如果该文件不存在，请尝试创建它。
append:
附加：
a Open for writing only; place the file pointer at the end of the file.If the file does not exist, attempt to create it.
a 只供写作；将文件指针放在文件末尾。如果该文件不存在，请尝试创建它。
So you want to append, not write.
所以你想追加，而不是写。
If the file doesn't exist, it'll try to create it. So just give the file a unique name that changes with the day. See datedocs for examples.
如果文件不存在，它会尝试创建它。因此，只需为文件指定一个随时间变化的唯一名称即可。有关示例，请参阅日期文档。
$filename = date("m.d.y"); // 03.10.01

<?php
$File = "YourFile.txt";
$Handle = fopen($File, 'w');
$Data = "Jane Doe\n".PHP_EOL;;
fwrite($Handle, $Data);
$Data = "Bilbo Jones\n";
fwrite($Handle, $Data);
print "Data Written";
fclose($Handle);
?>
Above is simple example to do it in php
以上是在 php 中执行此操作的简单示例

I haven't written a lot of php, but if you replace "w" with "w+" in fopen() it'll open the file and place the pointer at the end of it if the file already exists, making any fwrite() calls append to the file.
我没有写很多 php，但是如果你在 fopen() 中用“w+”替换“w”，它会打开文件并将指针放在它的末尾（如果文件已经存在），使任何 fwrite( ) 调用附加到文件。
$file_handle = fopen("testFile.txt", "w+");

edit:saw sachleen's answer and yes, you could combine the date (down to the day) with the file name. So that on a new day a new file would be created for that day and if the file exists for that day, it will be appended to.
编辑：看到 sachleen 的回答，是的，您可以将日期（精确到当天）与文件名结合起来。因此，在新的一天，将为该天创建一个新文件，如果该文件在当天存在，则将其附加到。
