This function checks to ensure that the file designated by
|
|
<parameter>filename</parameter> is a valid upload file (meaning
|
|
that it was uploaded via PHP's HTTP POST upload mechanism). If
|
|
the file is valid, it will be moved to the filename given by
|
|
<parameter>destination</parameter>.
|
|
</para>
|
|
<para>
|
|
If <parameter>filename</parameter> is not a valid upload file,
|
|
then no action will occur, and
|
|
<function>move_uploaded_file</function> will return
|
|
&false;.
|
|
</para>
|
|
<para>
|
|
If <parameter>filename</parameter> is a valid upload file, but
|
|
cannot be moved for some reason, no action will occur, and
|
|
<function>move_uploaded_file</function> will return
|
|
&false;. Additionally, a warning will be issued.
|
|
</para>
|
|
<para>
|
|
This sort of check is especially important if there is any chance
|
|
that anything done with uploaded files could reveal their
|
|
contents to the user, or even to other users on the same
|
|
system.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
<function>move_uploaded_file</function> is both &safemode;
|
|
and <link linkend="ini.open-basedir">open_basedir</link>
|
|
aware. However, restrictions are placed only on the
|
|
<parameter>destination</parameter> path as to allow the moving
|
|
of uploaded files in which <parameter>filename</parameter> may conflict
|
|
with such restrictions. <function>move_uploaded_file</function> ensures
|
|
the safety of this operation by allowing only those files uploaded
|
|
through PHP to be moved.
|
|
</para>
|
|
</note>
|
|
<warning>
|
|
<para>
|
|
If the destination file already exists, it will be overwritten.
