php_ini_scanned_files

PHP_INI_SCANNED_FILES(3)						 1						  PHP_INI_SCANNED_FILES(3)

php_ini_scanned_files - Return a list of .ini files parsed from the additional ini dir

SYNOPSIS

       string php_ini_scanned_files (void  )

DESCRIPTION

       php_ini_scanned_files(3)  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.

RETURN VALUES

	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(3).

EXAMPLES

       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>
";
		      }
		  }
	      }
	      ?>
