How can PHP configuration settings, such as memory_limit in php.ini, be adjusted to prevent memory errors?

Memory errors in PHP can be prevented by adjusting the memory_limit setting in the php.ini configuration file. This setting determines the maximum amount of memory that a PHP script can use. By increasing the memory_limit value, you can allow PHP scripts to consume more memory, which can help prevent memory errors.

// Increase memory limit to prevent memory errors
ini_set('memory_limit', '256M');
