file_put_contents

매개변수

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 (explained above).

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 (with some restrictions), joined with the binary OR (|) operator.

Available flags

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.
FILE_TEXT	data is written in text mode. If unicode semantics are enabled, the default encoding is UTF-8. You can specify a different encoding by creating a custom context or by using the stream_default_encoding() to change the default. This flag cannot be used with FILE_BINARY. This flag is only available since PHP 6.
FILE_BINARY	data will be written in binary mode. This is the default setting and cannot be used with FILE_TEXT. This flag is only available since PHP 6.

context

A valid context resource created with stream_context_create().
