Are there any best practices for iterating through arrays in PHP using foreach loops?

When iterating through arrays in PHP using foreach loops, it is important to follow best practices to ensure efficient and effective code execution. One common best practice is to use the key-value pair syntax in foreach loops to access both the key and value of each element in the array. This allows for more flexibility in handling array elements within the loop. 

// Example of iterating through an array using foreach loop with key-value pair syntax
$colors = array("red", "green", "blue");

foreach ($colors as $key => $value) {
    echo "Key: " . $key . ", Value: " . $value . "\n";
}
