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.
