How does changing the PHP version on a server affect the functionality of scripts?

Changing the PHP version on a server can affect the functionality of scripts because different PHP versions may have different features, functions, or syntax. This can lead to compatibility issues or errors in scripts that were written for a specific PHP version. To solve this issue, you may need to update or modify your scripts to be compatible with the new PHP version. 

// Example of updating a script to be compatible with PHP 7.4
// Before
$var = "Hello, World!";
echo $var;

// After
$var = "Hello, World!";
echo $var;
