How long does it take to learn PHP?

PHP is almost the easiest popular language to get started with. If you are familiar with the syntax and commonly used functions, you can do some simple web development. It takes 1 to 4 months to learn the basics of PHP to become proficient in it, but it will take at least a year to become proficient.

PHP also contains a lot of things. If it is simple, it will take about 2 months to learn a small message board, but there are many other things in PHP such as object-oriented, GD library, cookie, session... …. If you want to build a truly decent website, CSS, JS, and SQL are also essential (ajax is nothing more than js css as the front end, and php, asp or jsp as the backend). If you have to learn all of these, it will take at least a year.

If you just want to learn PHP so that you can understand and modify popular application codes such as PHPWind, Discuz, WordPress, etc., it will take about 3 or 4 months.
