What Is Minification?
Before diving into PHP minification, first, you need to understand what minification is and how it works.
Minification is a technical method for removing unnecessary characters, white spaces, line breaks, and comments from a code without changing its functionality. The ultimate goal of applying the minification method is to reduce the coding file size, automatically reducing the total page file size.
The coding files that can be minified:
HTML file
CSS file
Any scripting language like JavaScript file
PHP file
HTML minification:
Let’s understand with an HTML code example. In the code below, you can see that many unnecessary comments, white spaces, and line breaks are used to increase the code’s readability. However, this affects the PageSpeed performance by increasing the total page size.
Syntax
<html lang="en-US">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<!--adding a title for minifying HTML-->
<title>My minified files </title>
</head>
<body>
<!--adding an image file in HTML file-->
<img src="minify html.png" alt="My test image" />
</body>
</html>After minifying the HTML file, the minified HTML files will look like the below:
<html lang="en-US"><head><meta charset="utf-8"><meta name="viewport" content="width=device-width"><title>My minified files</title></head><body><img src="minify html.png" alt="My test image"></body></html>CSS Minification:
Let’s see how it works for CSS files with an example. without minification, The CSS code looks like the below:
Syntax:
body {
background-color: red;
}
h1 {
color: lightblue;
text-align: left;
}
p {
font-family: verdana;
font-size: 10px;
}After minification:
body{background-color:red}h1{color:#add8e6;text-align:left}p{font-family:verdana;font-size:10px}Explaining PHP Minification With An Example
PHP is an open-source server-side scripting language used in web development to create dynamic web pages. PHP minification involves deleting unnecessary comments, link breaks, and white space from the PHP code that are added by a developer to make the code readable. This would reduce the PHP file size.
For example: before minification, the code looks like the below.
// Function used for assigning new
// value to $string variable and
// printing it
function print_string( $string ) {
$string = "Example for PHP code"."\n";
// Print $string variable
print($string);
}
// Driver code
$string = "PHP minification"."\n";
print_string($string);
print($string);
?>After applying the minification method the PHP code looks:
<?php function print_string($string){$string="Example for PHP code"."\\n";print($string);}$string="PHP minification"."\\n";print_string($string);print($string); ?> The Helpful Tools To Minify PHP
