PHP Exercises, Practice, Solution

What is PHP?

PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

The best way we learn anything is by practice and exercise questions. We have started this section for those (beginner to intermediate) who are familiar with PHP.

Hope, these exercises help you to improve your PHP coding skills. Currently, following sections are available, we are working hard to add more exercises. Happy Coding!

Note: It's fine if you are playing around with PHP codes with the help of an online PHP editor, to enjoy a full-fledged PHP environment (since online editors have several caveats, e.g. embedding PHP within HTML) up and running on your own machine is much better of an option to learn PHP. Please read our installing PHP on Windows and Linux if you are unfamiliar to PHP installation.

PHP: Tips of the Day

PHP: "date(): It is not safe to rely on the system's timezone settings..."

You probably need to put the timezone in a configuration line in your php.ini file. You should have a block like this in your php.ini file:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

If not, add it (replacing the timezone by yours). After configuring, make sure to restart httpd (service httpd restart).

Here is the list of supported timezones.
