[PHP] Re: Yaf_Route
Hey Laruence,
I have tried the below example, but did not really get it work.
My code looks like this:
public function _initRoute(Yaf_Dispatcher $dispatcher) {
$route = new Yaf_Route_Regex (
"#(.*)#",
array(
"controller" => "index",
"action" => "index",
),
array(
1 => "test",
)
);
Yaf_Router::addRoute ('regex', $route);
}
Any ideas about what I am doing wrong?
Thx,

[PHP] Re: Yaf_Route
Hi:
Yaf_Router::addRoute is not a static method.
you should do like:
$dispatcher->getRouter()->addRoute("regex", $route); //
http://www.php.net/manual/en/yaf-dispatcher.getrouter.php
btw: when you in development environ, it is useful to keep
error_reporting on and look at error_log when you get some problems :)

[PHP] mcrypt_encrypt help needed
Hello all.
I am using the following function to encrypt a string:
define('SALT', 'myvalueforsalthere');
function encrypt($text)
{
return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256,
SALT, $text, MCRYPT_MODE_ECB,
mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB), MCRYPT_RAND;
}
and then:
$myval="hello";
$mayval= encrypt($myval);
echo decrypt($myval);
returns "hello" great.
But when my input string is more complicated I get unprintable
characters out of the decyrpt side:
$myval="var1=1&var2=2&var3=3";
The above when decrypted will spit out a string of unprintable
characters.
Is encrypt/decrypt choking on the "=" sign? I tried:
$myval=htmlentities($myval);
But it did not work. Any help is appreciated.
Thanks,
--Rick

Can you post your decrypt function too?
You create a random IV here, don't you need that IV to decrypt too?

I doubt it's choking on anything. htmlentities is only for safe output
to browser, you can always check the 'real' value by looking at the
page source in your browser.

Hi Rick,
Can you show us the decrypt function, too (even though it should be just
the reverse order of operations using a decrypt function, I'd just like to
double check it before commenting.) By the way, I wouldn't recommend using
ECB mode unless you have a special circumstance:

You're normally right, Matijn,
However, ECB mode doesn't use an IV, so even though he's generating an IV,
it's not being used (and, the benefit of an IV is one of the main reasons
you try to avoid ECB.)

Ah, I see, you're right. I thought he was using CBC (which I would recommend).
That also means that example #1 is wrong at mcrypt_encrypt help page[1].

Nice catch in the documentation, Matijn. While it will encrypt and decrypt
successfully, the IV isn't being used, so it would seem to be a better
illustration of use of someone switched the mode to one that's using the IV.
Someone with access to the documents want to make the change to one of the
other modes (as Matijn pointed out, CBC is pretty common?)

I tried to submit a bug report, but the PHP version that comes with
Ubuntu Server (oneiric) is 5.3.6, and they only accept bug reports
from version 5.3.8 and above. If anyone else wants to, please do so.
In that case, there's a second related bug, which is that
mcrypt_get_iv_size does not return 0 for ECB modes, which it should
(as the documentation also notes).

[PHP] compare dates
I'm puzzled why the if statement executes as true when the first date
(job_closedate) is not less than the second date (now).
The if statement claims that "12/02/2011" is less than "11/30/2011".
if (date("m/d/Y",strtotime($jobs_closedate)) <=
date("m/d/Y",strtotime("now"))){
echo date("m/d/Y",strtotime($jobs_closedate)); // displays -
12/02/2011
echo date("m/d/Y",strtotime("now")); //
displays - 11/30/2011
$error.="The close date must be later than
today's date, " . date("m/d/Y",strtotime("now")) . ".\n";
}
If the first date is "11/16/2011" the if statement also executes as true which
is correct since "11/16/2011" is less than "11/30/2011".

You're comparing strings here, try to compare the unix timestamp:
if (strtotime($jobs_closedate) <= strtotime("now")){
That'll probably do what you want..

Your decrypt function seems fine, and the encrypt/decrypt functions
work fine both in the same file for me. Now you say you use
$_GET["myval"], which means you get them from URL. Base64 is not URL
safe, have you used urlencode()?

Another way to do it would be:
if(strtotime($jobs_closedate)<=time()) {
}
or
if(date("Y-m-d",strtotime($job_closedate))<=date("Y-m-d",time()) {
}
Take care,
