This will highlight all functions not previously defined in PHP for the e text editor.   They are assigned to the "entities" in the theme editor.  By default, they are highlighted only when originally defined, but not when they are in use in your code; this fixes that.  This also fixes the current setup to highlight numeric constants as such when used inside a custom function call or definition.

Add custom/user-defined function highlighting to the default PHP.plist for e text editor
