What potential issues can arise from using different versions of PHP and MariaDB?

Potential issues that can arise from using different versions of PHP and MariaDB include compatibility issues, performance degradation, and security vulnerabilities. To solve this problem, it is recommended to ensure that the versions of PHP and MariaDB are compatible with each other, and to regularly update both software to the latest versions to mitigate any potential issues. 

// Example code to check PHP and MariaDB versions compatibility
if (version_compare(PHP_VERSION, '7.4.0') < 0 || version_compare($pdo->getAttribute(PDO::ATTR_SERVER_VERSION), '10.4.0') < 0) {
    echo "PHP or MariaDB version is not compatible. Please update to the latest versions.";
}
