The file_put_contents function is used to write data to a file.

Its basic syntax is as follows:

file_put_contents(filename, data, flags, context)

Explanation of parameters:

  1. File name: the name of the file to write data into.
  2. Data: Information to be written to the file.
  3. Flags (optional): Specify the file writing mode, with a default value of 0 indicating data is overwritten. If set to FILE_APPEND, data is appended instead.
  4. context (optional): used to specify the context.

The sample code is shown below:

$file = 'example.txt';
$data = 'Hello, World!';
file_put_contents($file, $data);

The code above writes the string “Hello, World!” to the file example.txt.

If you want to write data in an appending manner, you can use the FILE_APPEND flag.

$file = 'example.txt';
$data = 'Hello, World!';
file_put_contents($file, $data, FILE_APPEND);

This way, each time the file_put_contents function is called, the data will be appended to the end of the file instead of overwriting the existing data.

I hope this helps you!
