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: Remove first 4 characters of a string with PHP

You could use the substr function to return a substring starting from the 5th character: 

$str = "The quick brown fox jumps over the lazy dog."
$str2 = substr($str, 4); // "quick brown fox jumps over the lazy dog."
