This function is identical to calling <function>fopen</function>,
|
|
<function>fwrite</function> and <function>fclose</function> successively
|
|
to write data to a file.
|
|
</para>
|

<para>
|

If <parameter>filename</parameter> does not exist, the file is created.
|
|
Otherwise, the existing file is overwritten, unless the

<constant>FILE_APPEND</constant> flags is set.

The data to write. Can be either a <type>string</type>, an
|
|
<type>array</type> or a <type>stream</type> resource (explained above).
|

</para>
|

<para>
|
|
If <parameter>data</parameter> is a <type>stream</type> resource, the
|
|
remaining buffer of that stream will be copied to the specified file.
|
|
This is similar with using <function>stream_copy_to_stream</function>.
|
|
</para>
|

<para>
|
|
You can also specify the <parameter>data</parameter> parameter as a single
|
|
dimension array. This is equivalent to
|
|
<literal>file_put_contents($filename, implode('', $array))</literal>.
