Templates can contain the usual HTML code:
Copy Code code as follows:
A helper is a PHP function defined by Symfony in a template. He outputs HTML code and is much faster than the actual HTML code we write ourselves. Using the Symfony helper, the output we get with the following code is the same as the usual HTML code above:
Copy Code code as follows:
If in the above code, we think that the version of the helper is not faster than writing the HTML code, the
