How can one ensure that PHP code is syntactically correct and error-free before execution?

To ensure that PHP code is syntactically correct and error-free before execution, you can use a syntax checker tool like PHP Code Sniffer or a code editor with built-in syntax checking capabilities. These tools will highlight any syntax errors or warnings in your code, allowing you to fix them before running the script. 

// Example using PHP Code Sniffer to check syntax errors
// Install PHP Code Sniffer: composer global require "squizlabs/php_codesniffer=*"
// Run: phpcs your_script.php

// Example using PHPStorm IDE with built-in syntax checking
// Open your PHP file in PHPStorm and it will highlight any syntax errors or warnings
