How would I remove an instance of a class inside a array The content is stored inside an array. and the array inside $_SESSION ['cart'] //My Items class variables are protected. class Item { protected $id; protected $name; .... I will have have Multiple instances of $item inside the array. Cant use unset because its protected $item = new Item($result->id, $result->name); $_SESSION['cart'][] = $item;

Hi, please help. I deliberately made a mistake in my query… can’t get the Exception to display an error message. public function updatename($name = null, $id = null) { if (!$id && $this->isLoggedIn()) { $id = $this->data()->id; } $parms = array(); $parms[] = array(':name', $name, PDO::PARAM_STR); $parms[] = array(':id', $id, PDO::PARAM_INT); if (!$this->_db->query("UPDATE users " . "SET name = :this_variable_not_found" . " WHERE id = :id", $parms)) { throw new Exception('There was a problem updating.'); } } public function query($sql, $data_in = array()) { $this->_error = false; if ($data_in) {// prepared query $this->_query = $this->_pdo->prepare($sql); // this example extends the pdo class foreach ($data_in as $arr) { if (isset($arr[2])) {// type supplied $this->_query->bindValue($arr[0], $arr[1], $arr[2]); } else {// no type supplied $this->_query->bindValue($arr[0], $arr[1]); // defaults to string type } } if ($this->_query->execute()) { $this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ); $this->_count = $this->_query->rowCount(); } else { $this->_error = true; } } else {// non-prepared query $this->_query = $this->_pdo->prepare($sql); if ($this->_query->execute()) { $this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ); $this->_count = $this->_query->rowCount(); } else { $this->_error = true; } }// code to retrieve the result from the query.... return $this; }

i am watching a youtube tutorial for a register and login page the register and login parts work fine but once the user is logged in the logout button will not work it won't delete the session but if i delete the session using the inspect element of my browser and refresh the page the user will be logged out but the button will not work. here is the youtube part I'm up to. would like to continue with these parts once this problem is fixed I've tried a few debugging methods that you will see in my code witch there is a lot of but i think its all worth showing because the functions go across different files. index.php <?php require_once 'core/init.php'; if(Session::exists('home')) { '<p>' . Session::flash('home') . '</p>'; } $user = new User(); if($user->isLoggedIn()) { ?> <p>Hello <a href="#"><?php echo escape($user->data()->username); ?> </a></p> <ul> <li><a href="logout.php">Log out</a></li> </ul> <?php } else { echo '<p>You need to <a href="login.php">Log In</a> or <a href="register.php">Register</a></p>'; }

Hi everyone, I am starting to learn PHP OOP and would like to know if you could help me understanding the scopes a little bit better. I have created the below code during my courses, but cannot work out how to reuse $this->total in another class. I have set the $total; to protected and was wishing to be able to use it in my second class but it returned an error. Any idea how I could use this variable in another class while set with the scope of Protected please? Thank you so much! Class Calculator{ public $number1; public $number2; protected $total; function setNumber1($int){ $this->number1 = (int) $int; } function setNumber2($int){ $this->number2 = (int) $int; } function Calculate(){ $this->total = $this->number1 + $this->number2; } function getResult(){ return $this->total; } } $Calculator = new Calculator(); $Calculator->setNumber1(5); $Calculator->setNumber2(10); $Calculator->Calculate(); echo $Calculator->getResult() . "<br>"; Class secondCalculator extends Calculator { $this->total = $this->number3 + $this->number4; } Ben

Hey guys, got a bit of a complicated question for you... I was challenged to build a Finite State Machine based game by a friend with some rudimentary AI in php. After doing a little research, planned it out to have the following classes in this structure -world --food --nest ---ant Where world would be the highest level class, and contain all the instances of different objects + save/load functionality and such. The problem I'm having is acessing items in the higher level class, without either adding the initial declaration of $world as a global variable or just including a reference in the initial instance of each class item. I have to working, but it's nothing what I'd like. for instance: To access and sort through all the posx/posy coords of the ants presently on screen, I have to go: $this->world->checklocation($this->posx , $this->posy) using a reference I passed to it in the constructor(the world item). Is there a easier way to access information from a higher level object other then passing a reference to it from the original? Right now the only reason that the lower level objects know about the highest one at the moment, is I used the global keyword... and I'd rather know the right way of doing this, rather then the duct-taped way I'm using. (I've included the source code... warning though, it's messy and undocumented)

Hello i have the following error in php using this class. It seems it's because of the new modifications in php >= 5.2, how it handles this. I have no idea how to solve this problem tried with ArrayObject but didn't manage doing anything. I hope someone from here might help me Thank you very much for taking time and reading this post / answering.

Hi guys, I am new to php oop, I am trying get an object of sibling method inside a class, seems not working. here is how i do it. class Upload extends Base_controller{ private function sql () { $get = Upload::all(); } public function get_index() { dd($this->sql()->get); } }

Hi all, I hope you can help me out on this one, I am writing a class that uses soap to fetch data from a server but it gives me a 503 error when the server is not reachable, I am trying to catch it but it doesnt seem to be working: here is what I have so far, please note that i havent not put in the rest of the class so assume the rest is all good below the __construct() method as it is when the service is working and the SOAP errors are getting caught fine with this code, but the Service Unavailable i suspect cannot be caught? Is there another way i can approach this to achieve the same goal? class Khaos_model extends CI_Model { public $clientUrl = "https://999.999.999.999/censored.exe/";//obviously changed for forum public $client = false; public $connection = false; public $connectionerror = false; public function __construct() { parent::__construct(); try { $this->client = new SoapClient($this->clientUrl); $this->connection = true; } catch (SoapFault $fault) { $this->connectionerror = "SOAP Fault: (faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring})"; } // } Many Thanks
