This goes back to my earlier comment that the indentation of HTML only becomes an issue when you have embedded tables, which is usually the result of tables being used for layout control....

Since "good" coding practices include not using tables for layout, then any pages, people, etc who suffer from the HTML indentation problem would indicate that someone didn't use "good" coding sytles anyway...

I am happy to hear you got a job coding PHP.... amazing for someone who has only been coding in it a short time...

very FEW professional projects have an assigned and/or documented ... convention for variable names... at least in my experience... a team that works long together may develop a standard system simply by conforming to one or anothers habits... often by conforming to the lead developer's habits...

I often find that names used in one component of an OOP large scale project may be completely different from those used on another... So they are not common throughout... but as long as they are reasonable & well commented and each person is consistent, it is not too difficult to pickup someone elses code, when they have a different style than you, read it, and understand it...
