In both v1.37.1 and the code on the master-branch (running on Ubuntu 20.04) do not report any symbols for PHP code. Neither can I Ctrl+Click a symbol nor use "Go to Symbol Definition" to find the symbol definition. Other languages (like C) list the symbols on the file and allow me to go to the symbol definition. I have tried many PHP files and I verified that my PHP files are valid, yet Geany seems to not be able to parse out the symbols.
