As you can see by putting the dollar sign character ($) into a constant, you can use it with financial expressions and it won t be mistaken for a variable. By the way, you can use either echo or print (as well as other statements) in PHP to send output to the screen.

Arrays

An array is an object that holds several values. It s like a container on a container ship where different objects are stored dolls from China, car parts from Detroit, computers from Japan, and corn from Iowa. They work just as arrays do in JavaScript, but they re configured a bit differently. (See 12 for more on arrays.) Arrays are named like variables except they re assigned array objects. For setting up an array, you can use one of two basic formats. The preferred format works like an associative array. Instead of identifying an array element with a number, it s given a key with a value a key-value pair. Here s the general format for setting up an associative array:
QR Code Printer In Visual C#.NET
Using Barcode generation for Visual Studio .NET Control to generate, create Quick Response Code image in VS .NET applications.
$associate = array( key1 => value1 , key2 => value2 );
QR-Code Maker In .NET Framework
Using Barcode drawer for ASP.NET Control to generate, create QR-Code image in ASP.NET applications.
The other kind of array has a numeric key. Most typically, it s set up by listing the array elements in the following format:

Using Barcode maker for VS .NET Control to generate, create Denso QR Bar Code image in .NET applications.
$numeric=array( el0 , el1 , el2 ,3, true);
Code 3/9 Drawer In VS .NET
Using Barcode generation for .NET Control to generate, create Code 3 of 9 image in .NET applications.
However, it can be set up using the key=>value method as well:

$assoNum = array(0 => value1 ,1 => value2 ,1 => value2 );
Generate UPC - 13 In .NET

The following little script (array.php in this chapter s folder at www.wiley.com/go/ smashinghtml5), shows several different combinations you can see:

Arrays are important in PHP because database data are often loaded into an array for output.

Objects and properties
EAN128 Creation In .NET
Using Barcode printer for ASP.NET Control to generate, create EAN / UCC - 14 image in ASP.NET applications.
Objects in PHP are based on user classes there s no Object() object like there is in JavaScript. Making a class is like creating an object with all the variables, arrays, constants, and functions you like in one place. Here are the basics of creating a class, adding properties, and adding methods in this example (PropMethod.php in this chapter s folder at www. wiley.com/go/smashinghtml5):
USS Code 39 Printer In C#
Using Barcode drawer for .NET Control to generate, create Code39 image in Visual Studio .NET applications.
< php class PropMethod { private $propString= I work well with HTML5 ; private $propNum=2044; private $propBool=true; public function showString() { echo $this->propString, <br> ; } public function showNum() { echo $this->propNum, <br> ; } public function showBool() { echo $this->propBool; } } $testPM=new PropMethod(); echo $testPM->showString(); echo $testPM->showNum(); echo $testPM->showBool(); >
UCC - 12 Encoder In C#.NET
Using Barcode encoder for Visual Studio .NET Control to generate, create UPC-A Supplement 2 image in VS .NET applications.
The output for that little class is:

PART IV: DYNAMIC HTML5 TAGS PLUS A LITTLE JAVASCRIPT AND PHP
Everything but the 1 was probably expected. Some languages will treat Booleans as either a true/false or 1/0 pairs. So true + true = 2, and true * false = 0. The $testPM object is the object, and it works just like every other object in other languages. In JavaScript, though, the object and property are separated by dots (.) while in PHP, they re separated by arrows (->). The following are equivalent:
myObject.myProp=20; //JavaScript myObject->myProp=20; //PHP
You ll find other differences, but the similarities are far more numerous between PHP and JavaScript.
KEY PHP OPERATORS
Like all Web languages, PHP has operators, and a full listing of them can be found in the official PHP manual at http://us.php.net/manual/en/language.operators. php. Here, just a few that will be used in the program to make an email application, and some others are unique in other ways. So while you ll have to depend on the manual for all PHP operators, the one examined in the next few sections will have you up and running.
