PHP templating engine for user input that doesn't throw exceptions on invalid syntax?

Question

PHP

Good afternoon!
Need a template engine for user input that doesn't throw exceptions on invalid syntax?
Those. if it encounters an invalid {{for}}, for example, without the last parenthesis:
{{for items as item}}
{{/for}
then it will skip it and will not throw an error.
The goal is to make emails editable with a WYSIWYG editor, i.e. there will be some kind of variable pool for the letter, which is thrown into the template, with the help of the template engine it should be processed without exceptions.
Thank you!
