It seems to me that one of the problems with PHP is that you have to
include code in your HTML pages. Even with the cleanest design, you
end up with HTML that looks like this:
html
Hello, ?php showusername(); ?. Your last login was ?php
showlastlogin(); ?.p
/html
This is ok, but it seems to
There seems to be no reliable information in the manual about how to
do this. I'm trying to use mcrypt 2.4 with php4.06, which should be a
compatible combination.
So far, I have gotten it to work like this:
$cypher = MCRYPT_RIJNDAEL_128;
$encrypted = mcrypt_encrypt($cypher, $key, $plaintext,
You can tell it using the variables from the server. Using Apache you
can access the variables specs at:
http://www.apache-ssl.org/docs.html
With Apache SSL is SSL_CIPHER returns the variable about SSL/TLS
ciphersuite.
Do you know how I would access that variable from PHP? Is that
Is there a function in PHP which can tell me the encryption strength
being used by the browser? I want to be able to put a little message
on the page saying, You are using strong encryption or Warning: you
should upgrade your browser to one which supports 128bit crypto.
Thanks

I have a PHP application, and I need to display some dynamic data as a
simple line graph (a gif or png). Is there a simple way to do this?
Maybe something I can compile in to PHP?
Thanks

I know that credit cards have standard formats: There's a standard
number of digits, and whether the card is Visa, MC, Amex, etc is
encoded in the number, and there is some kind of checksum, and I think
the expiration is also encoded in the number. All of this is obvious

PHP is a great language. It makes it fast and easy to create web
pages. However, one feature which is critical for doing rock-solid
stable websites is strong typing. The reason for this is that you're
dealing with untrusted user input. Strong typing helps because if you
are expecting an INT,
U... you could write a fuction like
function CheckInputAgainstRE( $val, $re )
{
if ( ! ereg( $re, $val ) )
{
( ... some kind of code that writes out an error message and dies
... )
}
return $val;
}
That's what I've done. I have a huge file full of
As you know, gases such as oxygen and acetylene are distributed to
welders in pressurized containers. As you can guess, it is very
important to put the right stuff in the right container. Let's say
you have a container of acetylene, and you accidentally top it up with
some pure oxygen. This
The one problem with all your musings is that there is no such thing as an
integer when it comes to transferring data over http. Everything comes as
a string. What is done with these strings when they get to the
application is what matters. It's not like there is an HTML form element
