The PHP "continue" Keyword: A Comprehensive Guide

As a PHP developer, you may have used loops to iterate through arrays or perform other tasks. The "continue" keyword is a control structure in PHP that allows you to skip over certain iterations of a loop based on a condition. In this article, we will explore the syntax and usage of the "continue" keyword in depth, and provide plenty of examples to help you master this important PHP feature.

Syntax

The "continue" keyword is used to skip over certain iterations of a loop in PHP. Here is the basic syntax for using the "continue" keyword in PHP:
