How can one optimize PHP code to prevent errors like unexpected $end?

To prevent errors like unexpected $end in PHP code, make sure all opening braces, brackets, and parentheses have corresponding closing ones. Also, check for any missing semicolons at the end of statements. Properly indenting your code can also help in identifying missing closing tags. 

<?php

// Incorrect code with missing closing brace
if ($condition) {
    echo "Condition is true";
// Missing closing brace for the if statement

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

?>
