Thanks to PHP, you need to study every day for three months to sign up, and you need at least two hours a day. I've never been able to spare so much time. It would be great if I could study online, have teachers available for guidance at any time, and arrange my own time instead of regular class hours. Now, I am as tired as a dog when I come home from work every day. I only occasionally have free time, so I open PHP Zhongwen.com and look at the tutorials on the website. I have recently been learning DZ development and blog development systems. grateful
