How can variable naming conventions improve code readability and prevent confusion in PHP foreach loops?

Variable naming conventions can improve code readability and prevent confusion in PHP foreach loops by using descriptive and meaningful variable names that clearly indicate the purpose of each variable. This makes it easier for other developers (or even yourself in the future) to understand the code without having to decipher vague or cryptic variable names. By following a consistent naming convention, such as using camelCase or snake_case, you can create a more organized and structured codebase that is easier to maintain and debug. 

// Example of using descriptive variable names in a PHP foreach loop
$users = ['Alice', 'Bob', 'Charlie'];

foreach ($users as $user) {
    echo "Hello, $user! ";
}
