Automatically create cache file with php And Quickly Loaded in PHP Files


Hi Today Discussed Automatically create cache file with php and Quickly loaded in php files large number of data in mysql database is once run this file the data automatically create cache file and then quickly loaded this file follows briefly discussed.

Automatically create cache file with php And Quickly Loaded in PHP Files
Automatically create cache file with php And Quickly Loaded in PHP Files

Your php file quick load speed  increased your web site each every page loaded auto created cache file follows code.

<?php
function getUrl () {
    if (!isset($_SERVER['REQUEST_URI'])) {
    $url = $_SERVER['REQUEST_URI'];
    } else {
    $url = $_SERVER['SCRIPT_NAME'];
    $url .= (!empty($_SERVER['QUERY_STRING']))? '?' . $_SERVER[ 'QUERY_STRING' ] : '';

    }
    return $url;
}

//getUrl gets the queried page with query string
function cache ($buffer) { //page's content is $buffer
    $url = getUrl();
    $filename = md5($url) . '.cache';
    $data = time() . '¦' . $buffer;
    $filew = fopen("cache/" . $filename, 'w');
    fwrite($filew, $data);
    fclose($filew);
    return $buffer;
}

function display () {
    $url = getUrl();
    $filename = md5($url) . '.cache';
    if (!file_exists("/cache/" . $filename)) {
    return false;
    }
    $filer = fopen("cache/" . $filename, 'r');
    $data = fread($filer, filesize("cache/" . $filename));
    fclose($filer);
    $content = explode('¦', $data, 2);
    if (count($content)!= 2 OR !is_numeric($content['0'])) {
        return false;
    }
    if (time()-(100) > $content['0']) { // 100 is the cache time here!!!
        return false;
    }
        echo $content['1'];
        die();
}

// Display cache (if any)
display();  // if it is displayed, die function will end the program here.

// if no cache, callback cache
ob_start ('cache');

PHP Execute a HTTP POST Using PHP CURL

Today Discussed PHP Curl Post Means PHP Execute a HTTP POST Using PHP Curl.Well, there's a hurdle -- the information isn't going to be saved on the localhost database -- it needs to be stored in a remote database that I cannot connect directly to.

PHP Execute a HTTP POST Using PHP CURL
PHP Execute a HTTP POST Using PHP CURL

  1. User will submit the form, as usual.
  2. In the form processing PHP, I use cURL to execute a POST transmission to a PHP script on the customer's server.
  3. The remote script would do a MySQL INSERT query into the customer's private database.
This solution worked quite well so I thought I'd share it with you. Here's how you execute a POST using the PHP CURL library.


Curl Post Code Follows

//extract data from the post
//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
 'lname' => urlencode($_POST['last_name']),
 'fname' => urlencode($_POST['first_name']),
 'title' => urlencode($_POST['title']),
 
);

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

Abstract Classes and Interface in PHP

Abstract Classes and Interface in PHP

Today we discussed Abstract Classes and Interface in PHP Data abstraction first what is abstraction. As from name it seem like something that is hidden.  Yes nature of the abstract classes are same.Abstract classes are those classes which can not be directly initialized. Or in other word we can say that you can not create object of abstract classes.

Abstract Classes and Interface in PHP
Abstract Classes and Interface in PHP
  1. What is abstract classes.
  2. What is interface
  3. How to implement abstract classes in php
  4. How to implement interface in php
  5. Different between abstract classes and interface.
What is abstract Classes

 Abstract classes always created for inheritance purpose. You can only inherit abstract class in your child class. Lots of people say that in abstract class at least your one method should be abstract. Abstract method are the method which is only defined but declared. This is not true definition as per my assumption. But your any class has at least one method abstract than your class is abstract class.Usually abstract class are also known as base class. We call it base class because abstract class are not the class which is available directly for creating object. It can only act as parent class of any normal class. You can use abstract class in class hierarchy. Mean one abstract class can inherit another abstract class also.

Abstract Classes and Interface in PHP

Abstract classes in php are simillar like other oop languages. You can create abstract classes in php using abstract keyword. Once you will make any class abstract in php you can not create object of that class.



abstract class abc
{
public function xyz()
{
return 1;
}
}
$a = new abc();//this will throw error in php

abstract class testParent
{
public function abc()
{
//body of your funciton
}
}
class testChild extends testParent
{
public function xyz()
{
//body of your function
}
}
$a = new testChild();


Implementation of abstract method



abstract class abc

{

abstract protected function f1($a , $b);

}

class xyz extends abc

{

protected function f1($name , $address)

{

echo "$name , $address";

}

}

$a = new xyz();





abstract class parentTest



{



abstract protected function f1();



abstract public function f2();



//abstract private function f3(); //this will trhow error



}



class childTest



{



public function f1()



{



//body of your function



}



public function f2()



{



//body of your function



}



protected function f3()



{



//body of your function



}



}



$a = new childTest();
