How can PHP memory limits and execution times impact the successful completion of a script that reads and processes a large number of files?

PHP memory limits and execution times can impact the successful completion of a script that reads and processes a large number of files by causing the script to run out of memory or exceed the maximum execution time set in the PHP configuration. To solve this issue, you can increase the memory_limit and max_execution_time values in the php.ini file or set them dynamically within the script using ini_set() function.

// Increase memory limit and execution time
ini_set('memory_limit', '256M');
ini_set('max_execution_time', 300); // 5 minutes

// Your script to read and process large number of files
