Day 10 - Let's Eat Cookie - Become PHP Expert in 30 days

[Vahaa11]

Do we need to use _ ( Underscore ) if our variable have three words ?
php_expert_name

Before we used like

secretNumber
userNumber
cowsCanFly

Any difference between these two variable type?

It is better we follow one type of coding style. So far PHP had no coding guidelines like many other programming languages. So we used whatever we like, but when working on a team, it is better we follow same coding conventions. In vShare, we use $video_info, $user_name etc.. At that time no such coding guidelines where present and we follow that rule in out code.

Now PHP have a coding style

http://www.php-fig.org/psr/psr-2/

This coding style is supported by many large projects as you can see on home page of that site

http://www.php-fig.org/

Laravel, Zend Framework 2, Symfony2, Joomla, Drupal, eZ Publish, phpBB, Doctrine, CakePHP, Composer and many more. This list include popular PHP frameworks like Zend, Symfony and Laravel.

But we can't change coding style of exisiting project in one day, there are lot of code to change, so it may take time, for newer code, it is better follow a coding style, so everyone do the same, not what each programmer like, this may it easy to read/understand code.

In the code, i used

$_COOKIE['php_expert_name']

It is better follow the PHP variable naming convention and use

$_COOKIE['phpExpertName']

I will update the script to avoid further confusion.

Can somebody explain this portion of the script ?

setcookie('phpExpertName', $_POST['phpExpertName'], time()+3600);

Why phpExpertName and $_POST['phpExpertName'] mentioned together ?

[vineesh]

I do understand that it is the syntax of cookie. Hope I am right.

<?
if(isset($_COOKIE['userName'])) {
echo '<h2 style="color:red">Hi ' . $_COOKIE[userName] . '!, welcome back.</h2>';
exit;
}


if(isset($_POST['userName']) && strlen($_POST['userName']) > 3) {
setcookie('userName', $_POST['userName'], time() + 3600);
echo '<h3 style="color:red">You may close the browser and re-login, I will remember your Name. </h3>';
} else {

echo '
<html>
<body style="background-color:#D9D9D9">
<form method="POST" action="">
<input type="text" name="userName">
<button type="submit">Click here</button>

</body>
</html>

';
