What is the purpose of the continue statement in PHP?

Hey there,

I've been using the "continue" statement in PHP for quite some time now, so I can definitely help you out with that. The main purpose of the "continue" statement is to selectively skip the rest of the code within a loop and move on to the next iteration. It is particularly useful when you want to skip certain iterations based on specific conditions.

For example, let's say you have a loop that iterates over an array of numbers. Within the loop, you have a conditional statement that checks if a number is even. If the number is odd, you can use the "continue" statement to skip the rest of the code within that iteration and move on to the next number. Here's an example to illustrate this:

php
$numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];



foreach ($numbers as $number) {

    if ($number % 2 !== 0) {

        continue; // Skips odd numbers

    }



    // Rest of the code for even numbers

    echo $number . " is an even number." . PHP_EOL;

}

Hey everyone,

I've also used the "continue" statement in PHP and wanted to add my thoughts to this discussion. In my experience, the "continue" statement is a handy tool when you need to skip a certain part of a loop iteration and proceed to the next one.

One practical application I encountered was in a "for" loop where I was processing a large set of data. Inside the loop, I had some conditions that determined whether I should perform certain calculations or not. When those conditions were not met, using the "continue" statement allowed me to skip the unnecessary calculations and move on to the next iteration efficiently.

Here's a simplified example to give you a better idea:

php
$data = [...]; // An array of data



for ($i = 0; $i < count($data); $i++) {

    if (someCondition($data[$i])) {

        // Perform calculations

        // ...

    } else {

        // Skip this iteration and move to the next one

        continue;

    }



    // Process the rest of the code for this iteration

    // ...

}
