In what situations should PHP users directly contact their hosting provider for assistance with scripts?

If PHP users are experiencing server-related issues such as slow performance, timeouts, or memory errors with their scripts, they should contact their hosting provider for assistance. Hosting providers can help troubleshoot and optimize server configurations to better handle PHP scripts. Additionally, if users encounter security vulnerabilities or compatibility issues with their hosting environment, contacting the provider can help address these concerns promptly.

// Example code snippet for optimizing PHP script performance by adjusting server configurations
ini_set('max_execution_time', 60); // Set maximum execution time to 60 seconds
ini_set('memory_limit', '128M'); // Set memory limit to 128MB
