<function>php_ini_scanned_files</function> returns a comma-separated
list of configuration files parsed after &php.ini;. These files are
found in a directory defined by the
<option role="configure">--with-config-file-scan-dir</option> option
which is set during compilation.
</para>
<para>
The returned configuration files also include the path as declared in
the <option role="configure">--with-config-file-scan-dir</option>
option.

<para>
Returns a comma-separated string of .ini files on success. Each comma is
followed by a newline. If the directive <option
role="configure">--with-config-file-scan-dir</option> wasn't set,
&false; is returned. If it was set and the directory was empty, an
empty string is returned. If a file is unrecognizable, the file will
still make it into the returned string but a PHP error will also result.
This PHP error will be seen both at compile time and while using
<function>php_ini_scanned_files</function>.
