# file_put_contents

(PHP 5)

file_put_contents -- Write a string to a file

## Description

int file_put_contents ( string filename, mixed data [, int flags [, resource context]] )

Identical to calling fopen(), fwrite(), and fclose() successively.

You can also specify the data parameter as an array (not multi-dimension arrays). This is equivalent to file_put_contents($filename, implode('', $array)).

As of PHP 5.1.0, you may also pass a stream resource to the data parameter. In result, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream().

## Parameters

filename

  The file name where to write the data

data

  The data to write. Can be either a string, an array or a stream resource (explained above).

flags

  flags can take `FILE_USE_INCLUDE_PATH`, `FILE_APPEND` and/or `LOCK_EX` (acquire an exclusive lock), however the `FILE_USE_INCLUDE_PATH` option should be used with caution.

context

  A context resource

## Return Values

The function returns the amount of bytes that were written to the file.

## ChangeLog

Version | Description
--- | ---
5.1.0 | Added support for `LOCK_EX` and the ability to pass a stream resource to the data parameter

## Notes

> Note: This function is binary-safe.

> Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Reference CL, Stream Functions.

> Tip: You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and Appendix M for a list of supported URL protocols.
