php_ini_scanned_files
(PHP 4 >= 4.3.0, PHP 5)
php_ini_scanned_files — Return a list of .ini files parsed from the additional ini dir
说明
string php_ini_scanned_files ( void )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.
The returned configuration files also include the path as declared in the --with-config-file-scan-dir option.
返回值
Returns a comma-separated string of .ini files on success. Each comma is followed by a newline. If the directive --with-config-file-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 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 php_ini_scanned_files().
范例
Example #1 A simple example to list the returned ini files
<?php
if ($filelist = php_ini_scanned_files()) {
if (strlen($filelist) > 0) {
$files = explode(',', $filelist);
foreach ($files as $file) {
echo "<li>" . trim($file) . "</li>
";
}
}
}
?>
