Debugging and Code
During application development, it is often necessary to display source code directly in the browser in a readable (colored) format. PHP has built-in tools that automatically recognize keywords, strings, and comments and color them accordingly.

Code Handling Functions Overview
highlight_file() |
Reads a file and prints content with highlighted PHP syntax. | highlight_file("test.php"); |
|---|---|---|
highlight_string() |
Takes a string and prints it with highlighted PHP syntax. | highlight_string($code); |
php_strip_whitespace() |
Returns code from a file without comments and whitespace. | Code minification |
1. Displaying Source Code (Highlight)
The highlight_file() and highlight_string() functions use PHP's
built-in color schemes. This is extremely useful if you want to show code examples on your website without manually
writing HTML tags for colors.
2. Minification (php_strip_whitespace)
When code goes into production, we sometimes want to reduce file sizes. This function removes all comments and blank lines, making the code smaller and faster for the interpreter to read.
