Start PHP builtin server for a Project without Apache

by · · leave a comment

To PHP developer, setting up new development environment is a repetitive job, it’s boring and take time when you want to test something quick on system that’s not yours. luckily, PHP include a built in server out of box from version 5.6 and today i’m going to show you how to execute it.

first, you will need a php project with index.php file. Then use terminal emulator to go to project root and execute this command :

php -S localhost:8080

You can now  access your project at this address on your browser : localhost:8080 , just simple like that.

Default entry point is index.php, but you can access other file.

 

This is good to see all requests come in or error. Can be used on the fly for quick debugging. hope you find it useful 🙂

Sometimes, you face database issues like this ‘integrity constraint violation: 1062 Duplicate entry ‘100000001’ for key’ . if you are not familiar with Magento, may be you will feel blind (like i was), debugging won’t go smoothly as usual.

Five common PHP design patterns

by · · leave a comment

php

Design patterns were introduced to the software community in Design Patterns, by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (colloquially known as the “gang of four”). The core concept behind design patterns, presented in the introduction, was simple. Over their years of developing software, Gamma et al found certain patterns of solid design emerging, just as architects designing houses and buildings can develop templates for where a bathroom should be located or how a kitchen should be configured. Having those templates, or design patterns, means they can design better buildings more quickly. The same applies to software.

Magento – fix the 404 error on the admin dashboard

by · · leave a comment

When I changed the URI to access to my dashboard, when I logged in again, there was a 404 error on the admin dashboard. It seems is something related to permissions and can be easily solved executing the following commands:

find . -type d -exec chmod 755 {} ;
find . -type f -exec chmod 644 {} ;
chmod o+w var media -R

If this doesn’t work, maybe the login form is not redirecting correctly. In that case we need to change the action url in the app/design/adminhtml/default/default/template/login.phtml file. Look for the «form» start tag:

<form method="post" action="" id="loginForm">

Change it to:

<form method="post" action="<?php echo $this->getUrl('adminhtml') ?>" id="loginForm">

that’s it, you have you familiar dashboard back 😀
