Web Application Development has come a long way from being just simple static HTML pages to really powerful, data driven and interactive portals. It’s now more than just websites or portals. Since the advent of Internet, stand alone Desktop based software have been replaced by multi-user Cloud Based Applications. These Web Applications can be accessed from different devices, be it computers, mobiles or tablets. Since its cloud based, the data is centrally stored in a server and can be retrieved from anywhere as the need arises.  But this does not mean the data is vulnerable and could be accessed by anyone. Requisite security measures are in place and can be customized as per the requirements. The beauty is, in the same application, say there are multiple users, so the access level to the data entry and retrieval and be defined.

PHP remains widely used Language in the area of Web Application Development. It was originally created by Rasmus Lerdorf in the year 1994. One can refer to the Official Website for more information. There are large number of resources for one to refer and start learning this awesome language and develop some amazing and useful applications. Some of the most famous Projects/Applications and widely which have been written in PHP are:

Pre-requisites to learn PHP, are one should have some knowledge about computer programming in general. Knowledge of HTML, CSS & JavaScript will definitely be helpful, since these are the integral part of any Web Application. But, the main requirement is sincerity and dedication.

500 Internal Server Error in CakePHP application

RJ45 Technologies General, PHP, Students, Web Development No Comments

A common problem encountered in CakePHP applications is when they are moved to the root folder, they end up showing 500 Internal Server Error. We encountered the same. When started with the development, we had used a temporay folder under a common domain name. But when the actual domain was pointed to the application, it was showing up 500 Internal Server error. To put it simply, if we suppose, the application is place under a folder “demo” under a domain name – ourwebsite.com , then it is accessible in the url – www.ourwebsite.com/demo . But if the application is moved to the root folder and accessed directly from www.ourwebsite.com , then it ends up showing 500 Internal Server Error.



The very simple solution to this problem is to check the .htaccess file in the application and change or add  RewriteBase /  .

For example –

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteRule    ^$ app/webroot/    [L]
RewriteRule    (.*) app/webroot/$1 [L]
</IfModule>

If RewriteBase / is not present, please add it or change RewriteBase / folder/subfolder to RewriteBase /




Reasons Why You Should Have A Website????

RJ45 Technologies Uncategorized No Comments

To have a website of one’s own has become truly essential in the last years. To have your own website gives your business invaluable advantages over the traditional modes of advertising. There are at least 7 reasons why you should bring your business online:

  • 1. Enhanced customer convenience:
    Searching for businesses, products and services over the Internet is much easier and quicker than leafing through the Yellow Pages, for example. Every time a potential or an existing client wants to find out more about your business, they can easily do so, especially if you have added a “FAQ” section. Your customers can always keep in touch with you and your business, all they need to know is your website’s address.
  • 2. Greater reachability of your business profile:
    Your business profile will be accessible from EVERYWHERE. No other ad medium provides such global coverage. You will not depend on restricted phone book entry presentations any more. What is more important, more and more customers are nowadays referring to the Internet when searching for products, services and businesses.
  • 3. Greater possibilities for promoting your business portfolio:
    People will not buy your products or services unless they know that they actually exist. You can tell your potential audience much more through a WEBSITE than you could possibly do via any print advertisements, Yellow Pages listings, or TV/radio commercials. There are no limitations as far as space, time, nationality and residency are concerned. You can say as many things as you want, to as many people as you wish. And your business representation can be as resourceful as is the Internet itself.
  • 4. Efficient low-cost advertising:
    Your website practically runs NON-STOP PROMOTIONS of your business! Your customers will always be able to obtain thorough up-to-date information about your services or products. Instead of having to rely on randomly aired TV or radio commercials, they can simply browse through your website whenever they like.
  • 5. 24/7 availability:
    A website is available to you 24 hours a day, 7 days a week, 365 days a year. It will be your hardest working employee, never getting sick, or taking a holiday. And you can rest assured that your website is always there for you – to answer your customers’ questions, or to collect their feedback on your behalf.
  • 6. Saves time:
    Prospective clients can learn about you and your business at any time of the day simply by visiting your website, so you won’t have to be present or involved with the process in any way. The time you would otherwise have spent on answering or re-directing your customers’ questions can be now saved and invested in other activities that can increase your profits and further enhance the scope of your business.
  • 7. Saves money:
    You can save a lot of money you would have otherwise spent on print ads, brochures, coupons, flyers, specials, newsletters or mailings. What’s more, updating the information on your website is always quick, easy and amazingly efficient, whereas regular renewals of printed materials can be quite expensive and time consuming. The fact is, nothing is more valued in any business than optimal productivity at minimum cost possible.

Increasing PHP Memory Limit and File Upload size in Wamp

RJ45 Technologies PHP, Students, Web Development No Comments

Most of you must have encountered this while while importing a large database in PHP MyAdmin, or any other MySQL interface. There is server time out or maybe the file upload size is limited to say 2 MB or so. All you need to do is, you have to edit you php.ini file to increase the PHP memory limit and the file upload size. If you are using WAMP, try these:



In C:\wamp\bin\apache\apache2.2.8\bin\php.ini (go to the respective directory if WAMP is installed in a different location)

Find:
post_max_size = 8M
upload_max_filesize = 2M
max_execution_time = 30
max_input_time = 60
memory_limit = 8M

Change to:
post_max_size = 750M
upload_max_filesize = 750M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

Then restart wamp for the changes to effect.

Hope this was useful to you.
