What are common reasons for installation problems with PHP scripts on servers?

Common reasons for installation problems with PHP scripts on servers include incorrect file permissions, missing dependencies, and syntax errors in the code. To solve these issues, make sure that the file permissions are set correctly, all necessary dependencies are installed, and the code is error-free.

// Example of setting correct file permissions
chmod('path/to/file.php', 0644);

// Example of installing dependencies using Composer
composer require vendor/package

// Example of checking for syntax errors in PHP code
php -l file.php
