PHP is the most popular language for writing server side code. It is possible to achieve the same purpose using a number of ways. You can design a beautiful system by yourself, or you can quickly slap together some pieces of code from the Stack Overflow, and it will work.

Of course, even if you are not yet a professional developer, you still want to write a clean code. In the future, diligently following these tips will help you get closer to the status of an experienced and attentive developer.

Use <?php

Do not use <? ?> and other placement methods in the php-script file. Yes, maybe everything works on your PC, but it’s not a fact that it will work on the other server. Some servers do not support short tags. Do not risk it: only use <?php. And by the way, do not use a closing php-tag. This is a sign of bad taste. And the closing tag at the end can lead to unexpected problems associated with random spaces or line breaks at the end of the withdrawal.

&lt;? ...?> // Wrong
&lt;?php ... // Right
&lt;? = $ Var?> // Wrong
&lt;?php echo $Var ?> // Right

Separate files with parameters

There is not a single good reason that would justify the keeping of settings in a single file with the script. Always create a separate file, and connect it in the beginning of the script. You will understand how important it is when you will have to edit a bunch of files because of the change in one parameter. It’s quite simple: include a “config.php” file.

Comments are your friends

An old code is always hard to understand, even if it’s yours. It is better to give yourself a couple of comments in key locations to reduce the time to understand the script.

/ Single line comment
/ ** Multiline 
comment **/

Also, check the PHPdoc. (https://www.phpdoc.org/)

Properly format the code

There is nothing worse than a huge block of code, whose author does not know about the existence of the Tab button. Even the comments will not save the situation – margins have come up in order to logically code snippets from each other. Here the code is formatted incorrectly:

function  f($x,$y) { $s = $y+$x;
    $r=3;
while ($s < 20) {
$r = $r - 1; $s = $s + 1; }
return $r; }
And this is the same code, but with the correct formatting:

function f($x, $y) 
{
    $s = $y + $x;
    $r = 3;
    while ($s < 20) {
        $r = $r - 1;
        $s = $s + 1;
    }
    return $r;
}

Initialize variables

Of course, PHP automatically creates variables when you try to use them. But don’t you think that the use of this feature is risky? A good practice is to always initialize variables even before the first use. This will make the code more understandable and will help to ensure that you do not accidentally access the uninitialized variable.
