<span class="function"><strong>php_ini_scanned_files()</strong></span> returns a comma-separated
list of configuration files parsed after <var class="filename">php.ini</var>. These files are
found in a directory defined by the
<strong class="option configure">--with-config-file-scan-dir</strong>
option
which is set during compilation.

<p class="para">
The returned configuration files also include the path as declared in
the <strong class="option configure">--with-config-file-scan-dir</strong>
option.

<p class="para">
Returns a comma-separated string of .ini files on success. Each comma is
followed by a newline. If the directive <strong class="option configure">--with-config-file-scan-dir</strong>
wasn't set,
<strong><code>FALSE</code></strong> 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
<span class="function"><strong>php_ini_scanned_files()</strong></span>.
