What are the best practices for iterating through an associative array in PHP?

When iterating through an associative array in PHP, it's important to use the `foreach` loop to loop through each key-value pair. This allows you to access both the key and the corresponding value in each iteration. By using this loop, you can easily iterate through the entire associative array and perform any necessary operations on each element. 

$assocArray = array("key1" => "value1", "key2" => "value2", "key3" => "value3");

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