How to Fix the 'Maximum Execution Time Exceeded' Error in PHP?

Resolving "Maximum Execution Time Exceeded" Error in PHP

The "Fatal error: Maximum execution time of 30 seconds exceeded" error occurs when a PHP script exceeds the server's maximum execution time limit. While increasing the time limit is a potential solution, it's crucial to address the underlying cause to prevent performance issues in the future.

Code Optimization

Thoroughly review your code to eliminate any potential inefficiencies or errors. Consider the following:

• Avoid creating endless loops or memory leaks.
• Optimize database operations using transactions and multi-insert queries.
• Remove unnecessary code or refactor it to improve efficiency.

CLI Execution

If code optimization is insufficient, consider running the script as a command line interface (CLI) script instead of as a web page call. PHP scripts executed via CLI are not subject to the execution time limit.

• Configure the JSON download as a cron job or implement a queue system to initiate the download as a background process.

Time Limit Extension

As a last resort, you can temporarily extend the execution time limit using either ini_set('max_execution_time', '300') or set_time_limit(300). However, it's recommended to address the root cause of the exceeded execution time rather than relying on this solution to prevent performance degradation in the long run.
