In what situations should PHP developers use explicit curly braces in control structures like foreach loops, and what are the benefits of doing so?

In situations where the code readability might be compromised or when there is a need for clarity, PHP developers should use explicit curly braces in control structures like foreach loops. This can help avoid potential errors and make the code easier to understand for other developers. Additionally, using explicit curly braces can prevent any unexpected behavior that might occur due to ambiguity in the code. 

// Example of using explicit curly braces in a foreach loop
$colors = ["red", "green", "blue"];

// Without explicit curly braces
foreach ($colors as $color)
    echo $color;

// With explicit curly braces
foreach ($colors as $color) {
    echo $color;
}
