grammar

 file_put_contents ( file , data , mode , context )

parameter	describe
file	Required. Specifies the file to be written into the data. If the file does not exist, a new file is created.
data	Optional. Specifies the data to be written to the file. Can be a string, array, or data stream.
mode	Optional. Specifies how to open/write files. Possible values: FILE_USE_INCLUDE_PATH FILE_APPEND LOCK_EX
context	Optional. Specifies the environment for file handles. context is a set of options that can modify the behavior of a stream. If null is used, it will be ignored.

illustrate

The parameter data can be an array (but not a multidimensional array).

Since PHP 5.1.0, the data parameter can also be specified as a stream resource. The cached data saved in the stream will be written to the specified file. This usage is similar to using stream_copy_to_stream() function.

Support for context parameters is added by PHP 5.0.0.
