Is there a place to find a list of the possible values for the PHP predefined constant PHP_OS ? I'd like to use this value for a system requirements check, but need to know how different operating systems are named in this variable. Through some searching, so far I've compiled the following list: CYGWIN_NT-5.1 Darwin FreeBSD HP-UX IRI...
Take an example login() function within a class Account. class Account { /* Class variables */ public function login() { if(isset($_POST['username']) else if(isset($_SESSION['accountId'])) return $this->_sessionLogin(); else if(isset($_COOKIE['username']) else return false; } ...
Hi, I'm building a small abstract class that's supposed to make certain tasks easier. For example: $var = class::get('id'); would run check if there's pointer id in the $_GET, returning a string or array according to parameters. This should also work for post and request and maby more. I'm doing it in the way there's function for all t...
I am trying to read get parameters in such a way that will not open up potential security issues. What I was thinking was matching the request parameter explicitly to what I expect and then setting a default for anything that doesn't match. For example: if ($_REQUEST['media'] == "video") $sort = "video"; elseif ($_REQUEST['media']...
Hi, I am trying to get the entire page URL as a string in PHP - so, if the requested URL is ./foo.php?arg1=test&arg2=test2, I get "./foo.php?arg1=test&arg2=test2". I know that I can get the ./foo.php part from $_SERVER and the variables from $_GET, but I was wondering if there's an easy way to do it in just one fell swoop. TIA. ...
Is there a superglobal reference to the user's country or is using the IP against a database of IP to Country lookups the best way to go? ...
I'm trying to transfer a large array between two sites in PHP. I'm the admin in both. The array is created on one site, and after its creation I wish to automatically redirect the user to the other site, and pass the processed array along. I cannot use the SESSION superglobal, as it is limited to a specific domain. GET is not suitable...
Hey everyone, some background info: In the config file for my website, I set the mysql database name, username and password based on the contents of $_SERVER['HTTP_HOST']. Because it is possible for this variable to not be set in the case of old (HTTP 1.0) requests and cron jobs, I include a file that spoofs the $_SERVER['HTTP_HOST'] va...
My url is something such as: "inventory.php?sorting=1" and so forth. Page loads fine but does not display the information properly. mysql_connect("localhost","user","pass"); mysql_select_db("database"); if ($sorting == 1){ $result = mysql_query("select * from vehicles ORDER BY year DSC"); } elseif ($sorting == 2){ $result = mysql_qu...
is this pointing to the directory where the current file is executed? ...
EDIT: (UPDATED) Maybe my question was not clear enough. Ok, lets put it this way: $arr["a"] = 10; var_dump($arr); $arr["b"] =& $arr["a"]; var_dump($arr); the first var_dump returns: array 'a' => int 10 While the second one returns: array 'a' => &int 10 'b' => &int 10 If I unset($arr["a"]) it will return: array 'b' => ...
Apparently there was confusion as to my original post so let me start over: I am essentially creating an online shopping cart which gives a manager the ability to enroll his/her employees for training services which we provide. We charge $49 for the services for every employee enrolled. The primary difference between this and a traditio...
We have multiple load-balanced webserver machines running the same PHP webapp (LAMP) and I'd like to run slightly different code on each server (for testing purposes). I was hoping to use the $_SERVER['SERVER_ADDR'] super global to do something like this: if ($_SERVER['SERVER_ADDR'] == 'XXX.XXX.XXX.XXX') { echo "Do one thing"; } elsei...
What is the benefit of using the super global $_SERVER['PHP_SELF']? ...
So, I don't come from a huge PHP background—and I was wondering if in well formed code, one should use the 'superglobals' directly, e.g. in the middle of some function say $_SESSION['x'] = 'y'; or if, like I'd normally do with variables, it's better to send them as arguments that can be used from there, e.g: class Doer { private $se...
I'm trying to grab each URL parameter and display them from first to last, but I want to be able to display any of the parameters anywhere on the page. How can I do this? What do I have to add or modify on my script? Here is an example of a URL value. http://www.localhost.com/topics/index.php?cat=3&sub1=sub-1&sub2=sub-2&su...
As a web developer, I'm always using this approach to something like a login form or other “save” operation (ignoring the dangers of directly accessing input variables): if (isset($_POST['action']) && $_POST['action'] == 'login') { // we're probably logging in, so let's process that here } To make this less tedious and keeping in ...
I'm probably being a little thick, but I can't seem to find an answer to this one. I'm moving from a server with register globals ON to one with it being off. It's a good thing, but unfortunately I have been used to years and years working with register globals being ON which has resulted in me writing sloppy code. I am now trying to fix...
I am getting tried of if isset($_GET['whatever'])... before the rest of my if statement. E_NOTICE errors are way to handy to turn off and for $_POST variables I have a solution in my init script.. $POST = (is_array( $_POST ) && count( $_POST ) > 0); I find this helps self posting scripts look clean. if ($POST) { // now do somethi...
Hey! I'm trying to add some sort of a superglobal in my app. It will only store a small integer, but I need it to be accessible from anywhere in my app. I know you can use the delegate for this, but wouldn't it be easier if you could just set a superglobal in your application (of course it has to be alterable)? So, what is the best wa...
