How can errors in one code section affect the execution of other code sections in PHP?

Errors in one code section can affect the execution of other code sections in PHP because PHP is an interpreted language. This means that PHP executes code sequentially, and if an error occurs in one section, it can halt the execution of the entire script. To prevent this from happening, you can use error handling techniques such as try-catch blocks to catch and handle errors gracefully without stopping the execution of the script. 

try {
    // Code section where errors might occur
} catch (Exception $e) {
    // Handle the error gracefully
    echo "An error occurred: " . $e->getMessage();
}
