extra Calligraphic phi

Question

Looking for a command for this calligraphic phi

(\varphi is not the same and \mathcal{\varphi} does not work).

Solutions working under mathjax are more preferred.

This is an L, not a phi. Indeed \mathscr{L} also works with MathJax. — egreg, Jan 26 '18 at 12:45

It seems to be not a phi, but rather an L for me. On http://detexify.kirelabs.org/classify.html, I found this solution:

\documentclass{article}

\usepackage{mathrsfs}
\begin{document}
$\mathscr{L}$
\end{document}

This also works in MathJax: $\mathscr{L}$
