Are there any specific PHP documentation resources you recommend for understanding array iteration and key access?

When working with arrays in PHP, it's important to understand how to iterate over the elements and access keys. The PHP documentation provides detailed information on array iteration using functions like foreach and array_keys. By referring to these resources, you can learn the syntax and best practices for efficiently working with arrays in PHP. 

// Example of iterating over an array and accessing keys
$colors = array("red" => "#ff0000", "green" => "#00ff00", "blue" => "#0000ff");

// Using foreach to iterate over the array and access keys
foreach($colors as $key => $value) {
    echo "Key: " . $key . ", Value: " . $value . "\n";
}

// Using array_keys to access the keys of the array
$keys = array_keys($colors);
print_r($keys);
