PHP-file_put_contents()

The file_put_contents() filesystem function in PHP will write string data to a file. It works the same as if you were to use fopen(), fwrite(), and fclose() together to write data to a file. The file will be created if the output file does not exist yet, and if it already exists it will be overwritten.
Here is the Example
