<title>Error Messages Explained</title>
<simpara>
There is a lot that can go wrong during a file upload. PHP returns apropriate
error messages beside the usual warnings. The error message can be found in the
["error"] segment of the array that is created during the file upload.
This is either $userfile["error"] if <link linkend="ini.register-globals">
register_globals</link> is turned on in &php.ini;, or
$HTTP_POST_FILES["userfile"]["error"] for PHP versions before 4.1.0, or at last
and mostly recommended $_FILES["userfile"]["error"].
Since PHP 4.2.0, PHP returns an appropriate error code along with the
file array. The error code can be found in the
<emphasis>["error"]</emphasis> segment of the file array that is created
during the file upload by PHP. In otherwords, the error might be
found in <varname>$_FILES['userfile']['error']</varname>. An example:
</simpara>
<para>
<variablelist>
<varlistentry>
<term><varname>UPLOAD_ERROR_A</varname></term>
<term><varname>UPLOAD_ERROR_OK</varname></term>
<listitem>
<para>
Value: 1; the uploaded file exceeds the upload_max_filesize directive
that is specified in &php.ini;.
Value: 0; There is no error, the file uploaded with success.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>UPLOAD_ERROR_B</varname></term>
<term><varname>UPLOAD_ERROR_INI_SIZE</varname></term>
<listitem>
<para>
Value: 2; the uploaded file exceeds the MAX_FILE_SIZE directive
that was specified in the html form.

<link ini="ini.upload-max-filesize">upload_max_filesize</link>
