Description:
------------
I take the sample code directly from your website.  This is not the first time sample code from it has not worked.

http://us.php.net/manual/en/function.filter-var.php

I have the latest PHP version, 5.2.6


I use "var_dump(filter_var('bob@example.com', FILTER_VALIDATE_EMAIL));"

Exactly what your website says.


PHP 5.2.6 says "Fatal error: Call to undefined function filter_var()"

I googled it and the old reason it should do that is on older PHP versions.  But mine is 5.2.6.



PS: I've had to so far do 20 tries to read your captcha and your site made me confirm this a million times, each time having to read a new one.  I think I should buy captcha-reading software from that Chinese website as it reads better than humans.

Reproduce code:
---------------
var_dump(filter_var('bob@example.com', FILTER_VALIDATE_EMAIL));

Expected result:
----------------
What it says at http://us.php.net/manual/en/function.filter-var.php



Actual result:
--------------
Fatal error: Call to undefined function filter_var() in /usr/local/www/[my website name removed]/www/register.php on line 172

[my website name removed] = I'd rather not post my website's name until it's ready to open.

I forgot to mention, phpinfo says "mod_filter" is loaded.

I checked and these also get "Fatal error: Call to undefined function" on 5.2.6 with phpinfo saying mod_filter is loaded

filter_var_array() 
filter_input() 
filter_input_array()

Please load the "filter" extension, not Apache's mod_filter.

Oops I was looking at the wrong thing.

Anyway, the manual says the filter extension is built in to version 5.2.0 and above and does not need to be installed.  And only older versions need it installed.

Proof it should be built into PHPH 5.2.0 and above.

http://pecl.php.net/package/filter  --  last release separately was in 2006.  And yet in the other bug reports, there are notes that they recently fixed bugs in it this year.

Right, I was wrong to ask for activating php_filter.dll in your php.ini

However, you are doing something wrong. Below is the bundled and activated module in 5.2.6 (win32). Please ask in php.install or double check your install (and error logs).
