If you are new to PHP or just need to refresh your skills, this is the place to start. This series of tutorials will give you the basic knowledge you will need to create a simple PHP website.
PHP is a reflective programming language originally designed for producing dynamic web pages.[1] PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.
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().
filenameThe file name where to write the data
dataThe 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.
contextA context resource
The function returns the amount of bytes that were written to the file, or FALSE on failure.
Note: This function is binary-safe.
Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Reference CLIX, 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 N for a list of supported URL protocols.
