  Function overloading and overriding is the Object Oriented Programming feature in PHP. Function overloading means multiple function have the same name but different parameters. But in case of function overriding, more than one functions will have same method signature and number of arguments. PHP doesn’t support function overloading directly like other languages such as C++, JAVA etc. But we can overcome this issue with using the PHP magic method __call(). So let’s see how overloading and overriding in PHP works. Function Overloading In PHP Function overloading contains same function name and that function performs different task according to number of arguments. Example <?php class Shape { const PI = 3.142 ; function __call($name,$arg){ if($name == 'area') switch(count($arg)){ case 0 : return 0 ; case 1 : return self::PI * $arg[0] ; case 2 : return $arg[0] * $arg[1]; } }

What is HTTP? The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients and servers. HTTP works as a request-response protocol between a client and server. Two HTTP Request Methods commonly used for request-response between a client and server: GET and POST The GET Method Following example which shows you how to use get method. http://www.example.com/test/demo_form.php?name1=value1&name2=value2 Following are GET Request Method Points. 1. Request can be cached 2. Requests can be bookmarked 3. Requests remain in the browser history 4. Requests have length restrictions 5. Requests should be used only to retrieve data 6. Requests should never be used when dealing with sensitive data 7. Maximum path length of 2,048 characters 8. Data visible to everyone in URL. 9. GET is less secure compared to POST because data sent is the URL. Following are POST Request Method Points. 1. Requests are never cached 2. Requests do not remain in

Hello friends today we will learn how to clear the cache client browsers. This technique is very simple. Just add a version parameter to the URL string which is either a random string or a random number. If you change your sites CSS and upload on the server you will get old result only. For solve this problem, simply add ?ver=1.1 to the CSS import at the head of the file. So the browser teat as a different file. Example: <link href="css/style.css" rel="stylesheet" type="text/css" /> Becomes <link href="css/style.css?ver=1.1" rel="stylesheet" type="text/css" /> Same you can apply for JavaScript files.

Here we are going to know how to create Prime Number What is Prime Number  : Prime number divide only 1 or itself that is a prime number Following is Prime Number Logic in PHP Step 1. Start your variable from 2 Step 2. Set flag =0. Step 3. Start your second variable means j from 2 and check in condition j <= i/2 Step 4. if i%j equal to 0 then flag=1 and break. Step 5. if flag=0 then it is Prime Number   for($i=2;$i<=50;$i++) {     $flag=0;         for($j=2;$j<=$i/2;$j++)             if(($i%$j)==0)             {                 $flag=1;                 break;             }         if($flag==0)         echo $i."is a prime number<br/>"; }

Building web applications with PHP is a pretty simple process. As a PHP developer, you can develop practically anything, including database layers, form validation programs, file upload applications, and so on. Once you've mastered the foundations of the object-oriented programe and learned how to implement certain common design patterns in real-world conditions, you should be armed with a useful toolkit comprised of all sorts of classes and functions that can be used any number of times. Although you may not be aware of this fact, your toolkit can be considered a general PHP development framework. The end result of your own efforts and skills as programmer. Sometimes, there are certain situations when the capabilities offered by your own framework simply aren't good enough to fit the requirements of a particular application. In a case like this, you can either upgrade your framework, which will probably require coding additional classes and functions, or you can pick up a thi

1. Use Part 1 instruction for table and database   2. Create  register.php <?php $con = mysql_connect("localhost","root",""); if (!$con){   die('Could not connect: ' . mysql_error()); } mysql_select_db("sampletest", $con); if($_GET['type'] == 'delete'){     $delquery = "delete from user where id='" . $_GET['id'] . "'";     mysql_query($delquery); }else if($_GET['type'] == 'update'){     $selquery = "select * from user where id='" . $_GET['id'] . "'";     $rsquery = mysql_query($selquery);     $arrquery = mysql_fetch_array($rsquery); } if($_POST['submitbutton'] == 'Add'){     $name= $_POST['name'];     $email= $_POST['email'];     $phone= $_POST['phone'];     $query= $_POST['query'];     $query = "insert into user (name, email, phone, query) values ('".$name."'

1. Create  Database: 'sampletest' Create Table structure for table 'user' CREATE TABLE IF NOT EXISTS `user` (   `id` int(11) NOT NULL AUTO_INCREMENT,   `name` varchar(250) NOT NULL,   `email` varchar(250) NOT NULL,   `phone` varchar(250) NOT NULL,   `query` varchar(250) NOT NULL,   PRIMARY KEY (`id`) ) 2. register.php <?php $con = mysql_connect("localhost","root",""); if (!$con){   die('Could not connect: ' . mysql_error()); } mysql_select_db("sampletest", $con); if($_GET['type'] == 'delete'){     $delquery = "delete from user where id='" . $_GET['id'] .
