Laravel : Best Practices

There are Many PHP Frameworks Available And I’ve worked with Zend, CakePHP, CodeIgniter then I picked up Laravel in 2014 and with version 4.2. Trust me, I totally love it now.

Speaking about Laravel, it is simple and comfortable to use, suitable to start with writing the production code, and gives a great boost to a development process. One thing that I love about Laravel is that it’s built using the best practices used in programming available in the current times.

Here are some simple things worth having in mind when developing in Laravel:

  • Try to make use of your .env file to the max you can.
  • Don’t create tables or index directly via PHPMyAdmin or console. Use Database Migration to create table, add/alter any fields, and commit those to Git repository.
  • Don’t insert fake values directly into the database for testing purposes. Create Seeder files or user Model Factory to populate your database.
  • Prefer to use Artisan CLI more than manually creating stuff, it’ll fasten up your productivity.
  • Make sure to boost performance using some artisan commands:
    php artisan route:cache
    php artisan config:cache
    php artisan optimize — force
  • Try not to write closures into your routes.php file, instead move them to your controller.
  • Use Named based Routing.
  • Be careful with the naming conventions when creating custom classes and functions, especially with your Models. Laravel works on a principle such that, for a table named users, it would expect it’s model name to be User.
  • Try to make Validation Requests separately for each request.
  • Although PHP has a class named DateTime to help you when reading, writing, comparing or calculating with date and time. It is recommended that you use the Carbon Library for dealing with dates.
  • Always keep yourself updated with the latest version, Laravel is updating real fast, so keep up the pace.
  • Always use gulp, Laravel Mix for compiling your scripts and sass into minified version for better performance, Laravel did the basic housekeeping for you.

How to replace plain URLs with links in JavaScript or PHP?

Hello Friends

If you want to convert plain text in to URLs in JavaScript or PHP. This is good solution for you.

In PHP :

public function makeLinks($str)
{
    $reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
    $urls = array();
    $urlsToReplace = array();
    if(preg_match_all($reg_exUrl, $str, $urls)) {
        $numOfMatches = count($urls[0]);
        $numOfUrlsToReplace = 0;
        for($i=0; $i<$numOfMatches; $i++) {
            $alreadyAdded = false;
            $numOfUrlsToReplace = count($urlsToReplace);
            for($j=0; $j<$numOfUrlsToReplace; $j++) {
                if($urlsToReplace[$j] == $urls[0][$i]) {
                    $alreadyAdded = true;
                }
            }
            if(!$alreadyAdded) {
                array_push($urlsToReplace, $urls[0][$i]);
            }
        }
        $numOfUrlsToReplace = count($urlsToReplace);
        for($i=0; $i<$numOfUrlsToReplace; $i++) {
            $str = str_replace($urlsToReplace[$i], "<a target='_balnk' href=\"".$urlsToReplace[$i]."\">".$urlsToReplace[$i]."</a> ", $str);
        }
        return $str;
    } else {
        return $str;
    }
}

In JavaScript

function makeLinks(text) {
 var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
 return text.replace(exp,"<a target='_blank' href='$1'>$1</a>");
}

Hope it helps.

Set php.ini Values Using .htaccess

Did you know that you can set php.ini values right inside the .htaccess file? It’s actually very easy.

The .htaccess Code

#format
php_value setting_name setting_value#example
php_value  upload_max_filesize  10M

Of course you could simply place these in the .htaccess file, but .htaccess is a viable alternative if your host doesn’t allow you to touch the php.ini file.

Prevent Your CSS and JavaScript Files From Being Cached

Some websites use highly volatile, oft-changing CSS and JavaScript files. In the case of these files, it’s important that the developer prevent browsers from caching them. How do we do that? By using a phantom querystring, of course. We’ll use PHP to tack the current time onto the file reference.

The PHP

<link href="/stylesheet.css?<?php echo time(); ?>" rel="stylesheet" type="text/css" >
<-- RENDERS -->
<link href="/stylesheet.css?1234567890" rel="stylesheet" type="text/css">

<script type="text/javascript" src="/site-script.js?<?php echo time(); ?>"></script>
<-- RENDERS -->
<script type="text/javascript" src="/site-script.js?1234567890"></script>

It’s a very simple technique and doesn’t affect your CSS or JavaScript code in any way.

Android Detection with JavaScript or PHP

Hello Friends

You have a web application and you want to detect that if your Application is opened from android device than it will be redirect to any other URL that will be Android compatible.This is a good solution for you.

What’s obvious is that Android development is a hot topic that will only grow. Here are a few methods by which you can detect iOS‘ main competitor: Android.

The JavaScript

Searching the user agent string for “Android” is the quickest method:

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid)
{
// Do something! // Redirect to Android-site? window.location = 'http://android.viralsolani.co';
}

The PHP

Again, we’ll use PHP’s strstr function to search for Android in the user agent:

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(stripos($ua,'android') !== false){// && stripos($ua,'mobile') !== false) {
header('Location: http://android.viralsolani.co');
exit();
}

Bonus! .htaccess Detection

We can even use .htaccess directives to detect and react to Android devices!

RewriteCond %{HTTP_USER_AGENT} ^.*Android.*$
 RewriteRule ^(.*)$ http://android.viralsolani.co [R=301]

And there you have it: three different Android device detection! Have fun with your mobile development!

How to Install Apache, PHP, MySQL and PHPMyAdmin in Ubuntu 11.04

If you are a PHP based web developer, you need all the software running and configured properly. Here I am talking about installing them One by One in your Ubuntu Desktop. We are installing all the applications from terminal.

How to Open Terminal:
So, to fire up the terminal follow any of these steps:

  1. If you are running Unity Desktop, click on the Ubuntu Logo at top left corner and type Terminal in the search application bar. Then click on the terminal icon.
  2. If you are running GNome Desktop, click on Applications->Accessories->Terminal
  3. For shortcut, you can also press Ctrl+Alt+T at once, to open the terminal.

How to install Apache:

1. Make sure you have the internet connection. To install apache execute the following command in the terminal:

1
sudo apt-get install apache2

It takes some time to download and install apache. After the setup completes, type http://localhost/ in your browser window to make sure apache is installed and running properly. If you see the page with It Works!, the setup of apache2 completes successfully.

How to Install PHP:

1. To install PHP 5, type following commands in the terminal one by one:

1
2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5

The first line installs PHP5 in the computer. The second one provides the PHP5 module for the Apache 2 webserver. If second one is not installed, then Apache cannot parse PHP codes in a web page.

2. After installing PHP5 and PHP module for apache, restart the apache with following code:

1
sudo /etc/init.d/apache2 restart

3. While restarting the apache server, if you see a warning as “Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName”, then you can fix this by creating a file with the Server name. To do this type the following command in the terminal:

1
sudo gedit /etc/apache2/conf.d/fqdn

When the text editor opens, type “ServerName localhost” inside the file and click Save. Then close it. Now restart again with the above code and you will see that the warning message has gone.

4. Now, we have successfully installed php and apache web server. However, still we don’t know if PHP is successfully installed. To check this, create a file inside /var/www/ folder named test.php as:

1
sudo gedit /var/www/test.php

and write following code in it

1
<?php   phpinfo();  ?>

Save the file and type this in browser: http://localhost/test.php

If you see the various information about PHP and installed modules there, then we can confirm that Apache is parsing PHP codes. Hence the installation is successful up to this point.

How to Install MySQL:

1. To install MySQL Server in ubuntu, type following code in terminal window:

1
sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

This will install latest mysql server and other necessary PHP modules for recognizing mysql functions from PHP code. While installing MySQL server, you may require to enter the password for MySQL root user.

How to Install PHPMyAdmin:

1. To Install PHPMyAdmin, type the following codes in the terminal:

1
sudo apt-get install phpmyadmin

While installing PHPMyAdmin, you may require to select the web server. In such case, tick the Apache2 Server and proceed with the installation. You may also require to input MySQL root user password during installation.

Once the installation completes, type this in your browser window to confirm the successful installation of PHPMyAdmin: http://localhost/phpmyadmin/index.php.

Now, you are finished. Your environment is setup and you can enjoy using all these applications. Next, you can install other applications that may be necessary such as Eclipse, GIMP etc.
