Thank you for the report, and for helping us make PHP better.

Whoops. Closed the wrong bug. Commit should be for #53531. 

You know you can make these changes via edit.php.net or just commit them 
yourself.

Actually no, I don't have enough karma to commit them to the En repository.

BTW, the pages that have typos are:

http://www.php.net/manual/

en/function.mcrypt-cbc.php
en/function.mcrypt-cfb.php
en/function.mcrypt-create-iv.php
en/function.mcrypt-decrypt.php
en/function.mcrypt-ecb.php
en/function.mcrypt-enc-get-iv-size.php
en/function.mcrypt-encrypt.php
en/function.mcrypt-generic-init.php
en/function.mcrypt-get-block-size.php
en/function.mcrypt-get-cipher-name.php
en/function.mcrypt-get-iv-size.php
en/function.mcrypt-list-algorithms.php
en/function.mcrypt-list-modes.php
en/function.mcrypt-module-close.php
en/function.mcrypt-module-get-supported-key-sizes.php
en/function.mcrypt-module-is-block-algorithm-mode.php
en/function.mcrypt-module-is-block-algorithm.php
en/function.mcrypt-module-is-block-mode.php
en/function.mcrypt-module-self-test.php
en/function.mcrypt-ofb.php
en/function.mdecrypt-generic.php


And these are the ones which were restructured:

http://www.php.net/manual/

en/function.mcrypt-get-key-size.php
en/function.mcrypt-module-open.php

Now you do: http://svn.php.net/viewvc?view=revision&revision=306327
