When you wrote "silent exits" I thought you were ranting about Ruby for a moment.

So now the poor man has his own verb?
The language is JavaScript. that of Mordor, which I will not utter here
This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a f***ing golf cart.
"I don't know, extraterrestrial?"
"You mean like from space?"
"No, from Canada."

I realize this is just a good old fashioned rant, but most of your gripes have to do with not knowing the language man. Plain and simple. Now, PHP is not the most modern language in the world, gotta give you that, but it has a LOT of functionality and runs on a lot of platforms. I mean a lot. It's still pretty dang speedy too. In this little place called reality, that's more important than hating it because of using $ to denote a scalar variable.
But hey, totally awesome rant nonetheless. 
I'd also stay away from Perl if you don't like PHP. Fair warning.

Yup, so I know it pretty well. It has some "wtf" things about it, but it's not nearly as bad as the people on CP that never use it make it out to seem. But in all fairness, it's not a modern language.

I thought so. So far you were the only one who defended it, I think. 
I used to code a lot in Perl, so I am familiar with weird syntax, also. Although I absolutely hate working with Perl, it still is very powerful and is still a valid and relevant tool.

Totally agree. Same thing with regex. It looks like someone took code and put it in a blender, and yet I'm still very glad we have it because of its flexibility when quickly writing searches in comparison to manually coding one.

In that, I agree. There is a simple elegance to it, I just wish there was some tool out there that did a Lint or equivalent to find all my stupid mistakes, like passing in $foo and using it like $foos.
Jeremy Falcon wrote: because of using $ to denote a scalar variable.
Wait, I don't have to use the $? I thought it was intended to make it clear this isn't a function definition. Regardless, me noob.
As a lightweight scripting language, it looks like it carries a lot less baggage than other things I've seen.

The short answer is, you gotta use it.

This is the biggest problem for the language, they're out there. But the only out-of-the-box solutions like you get with VS aren't free. Even still, there's some configuration that must take place.
Just the Unix-y way of life man. Microsoft excels at ease of use, Unix/Linux says piss off n00b unless you RTFM.

Touché.
Seriously though, the docs are out there, they just tend to be more decentralized than say MSDN. I found it's the same thing with learning wxWidgets too, part of the pain was just finding good documentation online. Open source drawback I suppose, everyone wants to code, nobody wants to write docs.
If I were just starting out with PHP and *nix these days, I'd totally be pouring myself into books at the very least to help the learning curve.

My frustration with their mentality is that the barrier to entry is too high, like you pointed out. I once had to change a password for a MySQL database, so I followed the instructions here[^]. Note the "'" (single quote) surrounding the password. Since I was doing it from a Windows command prompt there was a whole other level nobody mentioned. Doing it that way actually entered " ' "s in the password! And logging in became impossible. So changing the password was the only option, once I figured out what the issue was (at least fifteen minutes of "OH SH*T, WHAT DID I DO???")
Then there were four more hours ahead of me, because of a single friggin space! None of the examples online showed that the correct command is "mysqladmin -u root -p'xyz123' password newPassword". Note the lack of space between the "p" and the " ' ". I wanted to kill... And that wasn't my first exposure to their stuff.
I'm not afraid of command prompts, having once helped administer a Windows/Solaris hybrid network, but issues like the previous are far too abundant in that world. I want to actually get something done on my computer, not dig through documentation all day.

Oh yeah, that totally annoyed me too. At one point I read there was some technical reason for it, but at the end of the day I suspect that's a load of BS.

Fair enough, but just about any environment has its quirks. Although I don't have many examples I can think of off the top of my head (old age tends to do that), it still 'tis be true.

I wasn't going to say that the network involved Windows for Workgroups....  , so I know the aging feeling.
PS - If you ever have a moment, and care to give some feedback on PHP code, how could this program[^] be improved? That was a self-teaching marathon, having never really touched PHP before, and I'm certain there are probably many tricks I missed, and language issues that could be improved, but the end product seems to work. Thanks. (If not, no problem.)

It looks pretty solid. I do have a few nit-picky things, just to help tighten it up. Not required, but will help it run a bit smoother...
Article Code: require_once("phpPayPalIpnClass.php");
Relative paths are a no-go if you ever want to run this code on the command line instead of the web. That's because your current directory will be the directory you are in when calling the script and not the one the script is actually in. The web server dances around that. What I do is something like this in the main PHP file to the app to handle both web and command line invocations.
define('BASE_PATH', realpath(dirname(__FILE__)) . DIRECTORY_SEPARATOR);
require_once BASE_PATH . 'my/relative/path.php';
Article Code: $this->logger->log("Processing a payment.\r\n");
Instead of explicit line breaks like that, it's better to use the constant PHP_EOL, so platform translation happens automatically.
$this->logger->log("Processing a payment." . PHP_EOL);
Article Code: $_POST['txn_id']
A hacker can easily mess with GET or POST data. And, if you try to access a variable that way without checking for its existence first the script can crash and burn. So I always validate / sanitize my input and perform checks before using them. Something like this at the very least...
if(isset($_POST['txn_id']))
Article Code: $this->logger->log("\r\nSENT:\r\n" . $header . $response . "\r\n\r\n");
If you're using double quotes for a string literal you don't have concatenate strings to include variables. You can just type them as part of the string and PHP will translate it automatically.
$nl = PHP_EOL;
$this->logger->log("$nlSENT:$nl$header$response$nl$nl");
Anyway, that's at first glance. Should make it a bit more cool looking if nothing else.

Thanks! I'll change it up, and update the article in the next week or so with the improvements, with more thanks at that time!

Oh, one more (quick?) question, if I may. So this:
Quote: require_once BASE_PATH . 'my/relative/path.php';
would become something like this:
Quote: require_once BASE_PATH . '/home/user/phpPayPalController.php'
and exposing it that way (because anyone can look at the html for the landing page, which has to have that on it) doesn't make it easier to hack the db password and setup files that are at that protected subdirectory location?
Thanks!

Let's assume you have a PHP file in /home/myapp/myfile.php. Then BASE_PATH would end up being /home/myapp/ at this point. So you'd want to do do something like require_once BASE_PATH . 'myfile.php';. Whereas before it was just require_once 'myfile.php';. However, this way the file will be included regardless of how the script is executed.
Jeremy Falcon

Oh. OK. That means since the main entry file is an html page, visible onsite, the base path would be it, and the require_once would be something like require_once BASE_PATH . '../../../myFile.php';, depending upon how many subdirectories it was above the directory. Thanks.
|
|

|

Keep in mind the path would no longer be relative to the actual file doing the including, but to the BASE_PATH constant. So if you had something like /home/myapp/mymodule/myotherfile.php that included some files in say /home/myapp/newdir/awesome.php, you'd want to do something like this require_once BASE_PATH . 'newdir/awesome.php';.
Keep in mind, BASE_PATH is only set once, in the main file that's first run. It's then in the global scope as other files are included. So all other files just reference it.
Jeremy Falcon

So in my case, the top-level, visible file would have:
require_once BASE_PATH . '../../../phpPayPalController.php';
or however many levels were required, and all of the hidden files, below public, would also have the same thing, but the file names would be changed, i.e.,
require_once BASE_PATH . '../../../phpMyMailClass.php'; , even though they are all at the same location. That makes sense now.
Thanks! And Thanks for the time!

You wouldn't need to use .. in the path anymore. Think of BASE_PATH as pointing to the root of the application and all other files stem from that, not the actual file doing the including.
