(PHP 4 = 4.3.0)
php_ini_scanned_files() returns
a comma-separated list of configuration files parsed after
php.ini. These files are found in a
directory defined by the
--with-config-file-scan-dir. option which is set during
compilation.
Returns a comma-separated string of .ini files on
success. If the directive
--with-config-files-scan-dir wasn't set, FALSE is returned. If it was set and
the directory was empty, an empty string is returned. If a
file is unreconizable, 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 php_ini_scanned_files().
The returned configuration files also include the path
as declared in the
--with-config-file-scan-dir directive. Also, each comma
is followed by a newline.
