Hypertext Preprocessor :: PHP some time I used to call Personal Home Page

PHP is an open source server side scripting language that mainly used for developing web applications and web services.

The PHP is very simple for a beginner, but offers many advanced features for a professional script writer.

Three main areas where PHP scripts are used :

1. Server-side scripting
2. Command line scripting
3. Writing desktop applications

Advantages :

1. Open source
2. Simple and very easy to learn.
3. Support for both structural programming and Object Oriented Programming. Use of variable variables $$var.
4. PHP can be used on all major operating systems, including Linux, many Unix variants (including HP-UX, Solaris and OpenBSD), Microsoft Windows, Mac OS X, RISC OS, and probably others. PHP has also support for most of the web servers today. This includes Apache, Microsoft Internet Information Server, Personal Web Server, Netscape and iPlanet servers, Oreilly Website Pro server, Caudium, Xitami, OmniHTTPd, and many others. For the majority of the servers PHP has a module, for the others supporting the CGI standard, PHP can work as a CGI processor.
5. One of the most Sexiest feature of PHP is that it can plugin with most of the databases. It support with Adabas D, dBase, Empress, FilePro (read-only), Hyperwave, IBM DB2, Informix, Ingres, InterBase, rontBase, mSQL, Direct MS-SQL, MySQL, ODBC, Oracle (OCI7 and OCI8), Ovrimos, PostgreSQL, SQLite, Solid Sybase, Velocis and Unix dbm
6. Power ful built in functions. click here to see all php functions
7. PHP also has support services using protocols such as LDAP, IMAP, SNMP, NNTP, POP3, HTTP, COM (on Windows)
8. PHP has extremely useful text processing features, from the POSIX Extended or Perl regular expressions to parsing XML documents. For parsing and accessing XML documents, PHP 5 standardizes all the XML extensions on the solid base of libxml2 and extends the feature set adding SimpleXML and XMLReader support.
9. Easy deployment and cost effective hosting.

Disadvantages :

1. Security flaws due to unknown vulnerabilities .
2. Not good to create desktop Applications

Hello Friends,

I have wriiten a class for error reporitng in a php web application. It is a ready made one..

you have to provide your email id.

If you work in localhost it will provide you error in the same page as it occur

but in hosted application the client will only get a custom error message. The same time our error handler class will send a mail to your email id as it occure..

Configuration on error.class.php

/**
* Configuration variables.
* @param email
* @param time zone
* $param application name
*/

$email = ‘arunet@gmail.com’;
date_default_timezone_set(”UTC”);
$app_name = ‘Name of the application’;

Download Source code

save this file with extension .php

How to use it ?

Just include this line in each php page

<?php include_once(”error.class.php”) ;?>

Eg.

<?php
include_once(”error.class.php”);
$xmlstr = file_get_contents(’library.xml’);
?>

This is a nice and simple substitute to get_file_contents() using curl, it returns FALSE if $contents is empty.

<?php
function curl_get_file_contents($URL)
{
$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_URL, $URL);
$contents = curl_exec($c);
curl_close($c);

if ($contents) return $contents;
else return FALSE;
}
?>

Symfony is a full-stack framework , a library of cohesive classes written in PHP5 . Symfony provides an architecture, components and tools for developers to build complex web applications faster. Symfony help you to develop your applications @ early, low cost, secure scalable and maintain them easily .

Symfony Features
Symfony was built in order to fulfill the following requirements:

Easy to install and configure on most platforms (and guaranteed to work on standard *nix and Windows platforms)
Database engine-independent
Simple to use, in most cases, but still flexible enough to adapt to complex cases
Based on the premise of convention over configuration–the developer needs to configure only the unconventional
Compliant with most web best practices and design patterns
Enterprise-ready–adaptable to existing information technology (IT) policies and architectures, and stable enough for long-term projects
Very readable code, with phpDocumentor comments, for easy maintenance
Easy to extend, allowing for integration with other vendor libraries
Automated Web Project Features
Most of the common features of web projects are automated within symfony, as follows:

The built-in internationalization layer allows for both data and interface translation, as well as content localization.
The presentation uses templates and layouts that can be built by HTML designers without any knowledge of the framework. Helpers reduce the amount of presentation code to write by encapsulating large portions of code in simple function calls.
Forms support automated validation and repopulation, and this ensures a good quality of data in the database and a better user experience.
Output escaping protects applications from attacks via corrupted data.
The cache management features reduce bandwidth usage and server load.
Authentication and credential features facilitate the creation of restricted sections and user security management.
Routing and smart URLs make the page address part of the interface and search-engine friendly.
Built-in e-mail and API management features allow web applications to go beyond the classic browser interactions.
Lists are more user-friendly thanks to automated pagination, sorting, and filtering.
Factories, plug-ins, and mixins provide a high level of extensibility.
Ajax interactions are easy to implement thanks to one-line helpers that encapsulate cross-browser-compatible JavaScript effects.
Before you get started with symfony, you should understand a few basic concepts. Feel free to skip ahead if you already know the meaning of OOP, ORM, RAD, DRY, KISS, TDD, YAML,Prototype , PROPEL, and PEAR

The default windows distribution of PHP comes with GD. So enabling the GD extension should be as simple as opening your php.ini file and uncommenting the necessary line. So this line:


Code:
;extension=php_gd2.dll
Should look like this (Remove the preceeding semi-colon):


Code:
extension=php_gd2.dll
Generally, your php.ini file will be in the folder in which you installed PHP.
