file_put_contents
(PHP 5)
file_put_contents — Write a string to a file
Descrizione
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 flags is set.
Elenco dei parametri
- 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().
Valori restituiti
The function returns the amount of bytes that were written to the file, or FALSE on failure.

È possibile utilizzare una URL come un nome di file con questa funzione se fopen wrappers è stata abilitata. Per maggiori informazioni su come specificare i nomi di file vedere fopen() e List of Supported Protocols/Wrappers per avere la lista dei protocolli URL supportati.
