+### file_put_contents — Write data to a file
+
+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.
+
+#### Parameters: 
+
+##### 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().
+
+You can also specify the data parameter as a single dimension array. This is equivalent to file_put_contents($filename, implode('', $array)).
+
+##### flags
+The value of flags can be any combination of the following flags, joined with the binary OR (|) operator.
+
+
+| Flag | Description |
+| --- | --- |
+| FILE_USE_INCLUDE_PATH | Search for filename in the include directory. See include_path for more information. |
+| FILE_APPEND | If file filename already exists, append the data to the file instead of overwriting it. |
+| LOCK_EX | Acquire an exclusive lock on the file while proceeding to the writing. In other words, a flock() call happens between the fopen() call and the fwrite() call. This is not identical to an fopen() call with mode "x". |
+
+##### context
+A valid context resource created with stream_context_create().
+
+### Return Values
+This function returns the number of bytes that were written to the file, or FALSE on failure.
