How can unexpected $end errors be avoided in PHP code?

Unexpected $end errors in PHP code can be avoided by ensuring that all opening braces, brackets, and parentheses have a corresponding closing brace, bracket, or parenthesis. Additionally, using proper indentation and code formatting can help identify any missing closing characters. Finally, using an integrated development environment (IDE) with syntax highlighting can also help catch these errors before running the code.

<?php

// Incorrect code that may result in unexpected $end error
if ($condition) {
    echo "Condition is true";
// Missing closing brace for if statement

// Corrected code with proper closing brace
if ($condition) {
    echo "Condition is true";
}
