Just started working through this. Just got up to pho section chapter 3 or 4 I think.. Anyway my question

Anyone know a realistic time frame to get a good grounding with these?

Any ideas on how to remember what goes where and what does what with php ... MySQL found there querys on chapter 2 or 3 quite easy to grasp and remembered them like a charm php finding a little harder to remember what does what and when/how
