mb_encoding_aliases — Get aliases of a known encoding type

### Description

array mb_encoding_aliases ( string `$encoding` )

Returns an array of aliases for a known `encoding` type.

### Parameters

`encoding`

  The encoding type being checked, for aliases.

### Return Values

Returns a numerically indexed array of encoding aliases on success, or `FALSE` on failure

### Errors/Exceptions

Emits an `E_WARNING` level error if `encoding` is unknown.

### Examples

Example #1 mb_encoding_aliases() example

`<?php
$encoding = 'ASCII';
$known_encodings = mb_list_encodings();
if (in_array($encoding, $known_encodings)) {
$aliases = mb_encoding_aliases($encoding);
print_r($aliases);
} else {
echo "Unknown ($encoding) encoding.\n";
}
?>`

The above example will output something similar to:

        [1] => iso-ir-6
        [2] => ANSI_X3.4-1986
        [3] => ISO_646.irv:1991
        [4] => US-ASCII
        [5] => ISO646-US
        [6] => us
        [7] => IBM367
        [8] => cp367
        [9] => csASCII
    )
