Fixing the ‘continue’ Warning in PHP Switch Statements

warning: “continue” targeting switch is equivalent to “break”. Did you mean to use “continue 2”?

Yes, the warning message you encountered is indicating that the use of the continue statement within a switch statement is equivalent to using break instead. To avoid the warning, you can modify the continue statement to continue 2 if you intend to continue to the next iteration of the outer loop.

The continue statement is typically used within loops to skip the remaining code in the current iteration and move to the next iteration. However, when used within a switch statement, it can lead to a warning because the behavior of continue is different inside a switch block.

To address the warning, you should replace the continue statement with continue 2 if you want to continue to the next iteration of the outer loop. Here’s an example to illustrate the difference:

for ($i = 0; $i < 3; $i++) {
    switch ($i) {
        case 0:
            // Some code
            continue; // Change this to "continue 2" if intended to continue to the next iteration of the outer loop
        case 1:
            // Some code
            break;
        case 2:
            // Some code
            break;
    }
    // Code after the switch
}

In the example above, if you want to continue to the next iteration of the outer loop when $i is 0, you should change continue to continue 2. This will skip the remaining code within the switch statement and move to the next iteration of the outer loop.

By making this modification, the warning message should no longer appear, and your code will behave as expected.
