mcrypt_list_modes — Gets an array of all supported modes
This function has been DEPRECATED as of PHP 7.1.0 and REMOVED as of PHP 7.2.0. Relying on this function is highly discouraged.
Gets the list of all supported modes in the
lib_dir parameter.
lib_dir
Specifies the directory where all modes are located. If not
specified, the value of the mcrypt.modes_dir
php.ini directive is used.
Returns an array with all the supported modes.
Example #1 mcrypt_list_modes() Example
<?php
$modes = mcrypt_list_modes();
foreach ($modes as $mode) {
echo "$mode <br />\n";
}
?>
The example above will produce a list with all supported
algorithms in the default mode directory. If it is not set
with the mcrypt.modes_dir php.ini
directive, the default directory of mcrypt is used (which
is /usr/local/lib/libmcrypt).
