What are some best practices for iterating through associative arrays in PHP using foreach loops?

When iterating through associative arrays in PHP using foreach loops, it's important to remember that the key-value pairs are accessed using the arrow (=>) syntax within the loop. To ensure that you are iterating through all elements of the associative array, you can use the foreach loop with the syntax foreach($array as $key => $value). This allows you to access both the key and the corresponding value in each iteration. 

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

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