Passing data from php to js?

Question

PHP

I know, the most banal question, but still how to do everything right?
ajax is not an option, a page is generated = a request to the database, make ajax = 1 more request to the database, somehow it is not logical ...
or make 1 request and return it right there?
What do you think?

Answer 1

well, I don’t know, I pass it like this for angularJs

<script type="text/javascript" charset="utf-8">
    window.data = <?php echo CJSON::encode($data);?>;
</script>

Accordingly, in the Angular controller, the
rest is already ajax if necessary...

Answer 2

Give out the data that can be rendered when the page is loaded immediately.
If, due to user actions, new data should appear on the page, but you don’t want to reload the page, add / update data on the page using ajax.
