10 best tips to writing PHP code.

Tips to writing php code : PHP is generally most loving and used programming language among developers for developing web applications, for an example facebook, wordpress etc.

However, you might find coding in PHP challenging and a difficult task, especially when you’re just a beginner. So, to save you from many mistakes when writing PHP code in you project, I’ve listed some great points and tips that will help you to code in PHP correct way and a lot easier.

so here is 10 best tips to writing PHP code.

1. Replace If/Else With Ternary Operators (Tips to writing php code)

Rather than making use of an if/else statement, it would be superior if you use a ternary operator instead. Here’s a line of PHP code that explains ternary operator usage:

$todo = (empty($_POST[’todo’])) ? ‘default’ : $_POST[’todo’]; 

This line of code is equivalent to the following if/else statement:

if (empty($_POST[’todo’])) {
$todo = ‘default’;
} else {
$todo = $_POST[’todo’];

So, as you can see in the code above the ternary operator helps in making the code clutter-free and saves plenty of space using the if/else statement in a single line.

2. Ditch the Use Of <? … ?>

When you starting to write a PHP script, the standard and easy code declaration blocks use “<? php … ?>” script delimiters. However, beginners can make the mistake of writing the script delimiters as <? ... ?> instead of <?php ... ?>. Make sure to avoid such a situation. That’s because, <? ... ?> when used in a PHP script, it may work on your server easily, but it could be fail to work on other servers.

Second point, Please avoid the use of shortcut tags when echoing a variable. That’s because, those tags aren’t supported everywhere. To make your code more portable you need to prevent use of shortcut tags.

Basically, you just need to avoid writing your PHP script only with shortcut tags such as <?=$Var?>. You should rather write it as <?php echo $Var ?>.

3. Understand the Difference Between Comparison Operators (Tips to writing php code)

Comparison operators are an important and useful part in PHP. But let’s face it and solve it, because some programmers fail to find the difference between comparison operators, such as ‘==’ and ‘===’. Remember that == is for checks and equality whether the value on the left and right side are equal. On the other side, === not only looks for whether the values on both sides are equal, but also checks whether the variable type is the same on both sides or not.

Just find the more detailed view and understanding of when you need to use the === comparison operator.

//This is an example of bad code 
if ( strpos( $inputString, 'abc' ) == false ) {
  // do something
//This is an example of good code
if ( strpos( $inputString, 'abc' ) === false ) {
  // do something

4. Use Relevant Variable Names

This is the most important step you should follow while writing PHP code, ensure using variable fickle names that add some value. Furthermore, include details about the data that those variables will store. Let’s assume, you using a variable as an integer. In that case, you must use a variable name with an “i” at the beginning. In fact, this is a very crucial point you must consider when writing PHP code in any project, since we don’t need or require specifying a type during variable declaration in PHP.


Below is a list of some meaningful variable names:

$iNum = 12; // For Integers
$fPi = 2.121956; // For Floats
$sName = "Mac"; // For Strings
$bIsMember = false; // For Booleans

5. Add Comments Alongside Each Important Action

Adding comments side-by-side to each most important action will help you identify the need for any specific PHP code snippet, especially when you are developing a large size project. In addition, mention helps make the code look better for other programmers who next gong to working on it same as you.

<!-- wp:syntaxhighlighter/code -->
<pre class="wp-block-syntaxhighlighter-code"></pre>
<!-- /wp:syntaxhighlighter/code -->

6. Use “str_replace()” Instead Of “ereg_replace()” and “preg_replace()”

If you want to improve the efficiency of your PHP code to replace strings, consider using str_replace() instead of using functions, such as: ereg_replace() and preg_replace(). In fact, its good to knwo that according to an online report, “str_replace() is 61% more efficient if you compared to other regular expressions.”

Consider using isset() over strlen() while checking out the length of a string, That’s because, the isset() function will help in making calls 5 times quicker. Your function call is another great advantage of using isset will remain valid regardless of whether the variable exists or not.

Here’s a simple example to demonstrate the use of the isset() function:

if (isset($username[8])) {
 // The username is at least nine characters long.

9. Prefer Using Single Quote Rather Than Double Quotes

While both single, as well as double quotes, serve several purposes, it is advised that you should use single quotes over double quotes. This is because the first option helps in executing the loops a lot faster. Let us see two different ways of printing long lines of information:

//Using double quotes
print “WorkStatus : $workstatus. Location: $location”;

Now, you need to check how the above line of code can be written by using single quotes and code:

//Using single quotes
print ‘WorkStatus : ‘.$workstatus’. Location‘.$location’.';
