What happens when you use continue in a loop in PHP?

When you use continue in a loop in PHP, it causes the loop to skip the remaining statements in the current iteration and proceed directly to the next iteration. This means that any code that follows the continue statement within that loop iteration will not be executed. Instead, control passes back to the loop's condition, and if the condition is still met, the next iteration begins.

For instance, consider a scenario where you're looping through an array and want to skip certain values. By using continue, you can effectively ignore those specific values and continue processing the rest of the array.

In contrast, terminating the loop or breaking out of it completely would require different control structures, such as break. Using continue allows for more granular control over the flow of the loop, enabling you to selectively bypass specific iterations while still keeping the loop active for the remaining iterations. This understanding is fundamental in mastering flow control in PHP programming.
