What are some best practices for troubleshooting Apache crashes related to PHP scripts?

When troubleshooting Apache crashes related to PHP scripts, one common issue could be memory exhaustion due to inefficient code or large data processing. To solve this, you can increase the memory limit in your PHP configuration file (php.ini) or optimize your code to use memory more efficiently.

ini_set('memory_limit', '256M');
```

Another potential cause of Apache crashes could be a fatal error in the PHP script. To identify and fix this, you can enable error reporting in your PHP script to display any errors or warnings.

```php
error_reporting(E_ALL);
ini_set('display_errors', 1);
