What potential issues may arise from running PHP 4.0.6 and 4.3.6 scripts together on the same server?

Running PHP 4.0.6 and 4.3.6 scripts together on the same server can lead to compatibility issues due to differences in syntax and functions between the two versions. To solve this problem, you can use version-specific conditional statements to ensure that the correct code is executed based on the PHP version running on the server. 

if (version_compare(PHP_VERSION, '4.3.0', '<')) {
    // PHP 4.0.6 code here
} else {
    // PHP 4.3.6 code here
}
