How can PHP developers ensure the proper functioning of their code by paying attention to syntax and logic errors?

PHP developers can ensure the proper functioning of their code by paying attention to syntax errors, which can be identified by using a syntax checker or IDE with syntax highlighting. Logic errors can be detected by thorough testing and debugging. By carefully reviewing and testing their code, developers can identify and correct any syntax or logic errors before deploying their application.

<?php

// Example code snippet with proper syntax and logic
$number = 10;

if ($number > 5) {
    echo "The number is greater than 5.";
} else {
    echo "The number is not greater than 5.";
}

?>
