In what ways can assumptions about script execution in different environments lead to overlooking potential bugs in PHP code?

Assumptions about script execution in different environments can lead to overlooking potential bugs in PHP code when developers don't account for differences in server configurations, PHP versions, or dependencies. To avoid this, it's crucial to test code on various environments and consider edge cases that may affect the behavior of the script. 

// Example of checking PHP version before executing code
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    // Handle code for older PHP versions
} else {
    // Code that is compatible with PHP 7 and above
}
