How can PHP configuration settings, such as "memory_limit" in php.ini, impact file import processes?

PHP configuration settings, such as "memory_limit" in php.ini, can impact file import processes by limiting the amount of memory that PHP scripts can use. If the memory limit is too low, it can cause the script to run out of memory and fail to import large files. To solve this issue, you can increase the memory limit in the php.ini file to allow the script to use more memory during the file import process.

```php
// Increase memory limit for file import process
ini_set('memory_limit', '256M');
```
This code snippet increases the memory limit to 256 megabytes for the file import process. You can adjust the memory limit value as needed based on the size of the files you are importing.
