How to create a instance of an array?

I want to create a cart like system to add items to an array and the display it. I don't know how to create an instance of an array and then save it into an another array.

$_SESSION['cart'] = array();
$_SESSION['cartitem'] = array($var1,$var2,$var3,$var4,$var5);
array_push($_SESSION['cart'], $_SESSION['cartitem']);
print_r($_SESSION['cart']);

I want to put the $_SESSION['cartitem'] into $_SESSION['cart'] and save it for next time so it adds another array next time into $_SESSION['cart'] and display all saved arrays.

Edit: I want to add a new $_SESSION['cartitem'] array to $_SESSION['cart'] so the output of $_SESSION['cart']after fist time will be Array ( [0] => Array ( [0] => 15 [1] => Big [2] => Solo [3] => Red [4] => 53 )) and second time Array ( [0] => Array ( [0] => 15 [1] => Big [2] => Solo [3] => Red [4] => 53 ) [1] => Array ( [0] => 16 [1] => Small [2] => Solo [3] => Blue [4] => 634 ) ) e.t.c ... so it adds another array from input values.

You are emptying cart every time with $_SESSION['cart'] = array();. Also, you can add cartitem easier. Oh, and you need session_start. Your small code sample doesn't make a lot of sense, but in general:

session_start();
$_SESSION['cartitem'] = array($var1,$var2,$var3,$var4,$var5);
$_SESSION['cart'][] = $_SESSION['cartitem'];
print_r($_SESSION['cart']);

Create new instance of an Array with Java Reflection Method, You need to call the constructor: DeckofCards myDeck = new DeckofCards(); // note parens! In Java, the parentheses are required. A new array instance is created using the Array.newInstance () method. Then the Array.set () method is used to set the values for the array. A code snippet which demonstrates this is as follows −. int arr [] = (int [])Array.newInstance (int.class, 5); Array.set (arr, 0, 5); Array.set (arr, 1, 1); Array.set (arr, 2, 9); Array.set (arr, 3, 3); Array.set (arr, 4, 7);

I created a file named var.php and added this code

<?php
    session_start();
    $_SESSION['cart'] = array();
?>
$_SESSION['cartitem'] = array($var1,$var2,$var3,$var4,$var5);
array_push($_SESSION['cart'], $_SESSION['cartitem']);
print_r($_SESSION['cart']);

Creating an instance of an array of objects class in Java, The following example will construct an instance of an array of fully_qualified_class_name and populate its values with instances given by val1 , val2 , etc. (This� A Java ‘instanceof array’ example. To that end, I created the following Java instanceof array example class. To make my findings really stand out well, I ended up creating two different methods, instanceTester, and arrayTester, and call both of them with a simple Java String array: /** * A Java ‘instanceof’ array example/test class.

You can create the cartitem array as an array value of the cart variable. So:

$_SESSION['cart'] = Array();
$_SESSION['cart']['cartitem'] = Array($var1......$var5);
print_r($_SESSION['cart']);

Array.CreateInstance Method (System), This time, however, the class will have an array instance variable. Make a temporary array that is bigger (by 10) than the instance variable. Copy the original� I can create a dummy instance of my requested array and then get the type from there. But I wonder if there is a way to get the type without creating the instance first? object myArrayInstance = Array.CreateInstance(elementType, 0); Type t = myArrayInstance.GetType(); // This is the desired type.

An array is a special variable, which can hold more than one value at a time.

That line� Array.from () lets you create Array s from: array-like objects (objects with a length property and indexed elements); or iterable objects (objects such as Map and Set). Array.from () has an optional parameter mapFn, which allows you to execute a map () function on each element of the array being created.

  • And what is the result of your current code? You are calling session_start() before any of this, right?
  • @PatrickQ yes i do , Array ( [0] => Array ( [0] => 15 [1] => Big [2] => Solo [3] => Red [4] => 53 ) )
  • Okay, so this is doing exactly what you want it to do except for "adds another array next time", which is covered by AbraCadaver's answer.
  • What are input values? And why define $_SESSION['cartitem']???
  • So the problem now is that it saves two same arrays $_SESSION['cartitem'] and I want it to remember last saved array and I want it to save multiple arrays with diffrent $var1....$var5 variables
  • I have no idea what you're asking. You'll need to add more description/examples to question.
  • I added Edit to main question so maybe now you will know what I want to achieve
