What are some best practices for implementing foreach in PHP code?

When implementing foreach loops in PHP code, it is important to follow some best practices to ensure clean and efficient code. One key practice is to properly initialize the array or iterable object before using it in the foreach loop to avoid errors. Additionally, using clear and descriptive variable names can improve code readability. Lastly, consider using the shorthand syntax for foreach loops when iterating over arrays. 

// Initializing an array and using foreach loop with clear variable names
$fruits = ['apple', 'banana', 'orange'];

foreach ($fruits as $fruit) {
    echo $fruit . "<br>";
}
