file_put_contents()

file_put_contents() — This function is identical to calling fopen, fwrite and fclose successively to write data to a file.

If filename does not exist, the file is created. Otherwise, the existing file is overwritten, unless the FILE_APPEND flag is set.

Inputs: filename: Path to the file where to write the data. data: The data to write. Can be either a string, an array or a stream resource. If data is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream. context: A valid context resource created with stream_context_create.

Returns: This function returns the number of bytes that were written to the file, or false on failure.
