Loops · Lesson 6 of 6

continue

Skip the rest of one iteration and move to the next.

Lesson

continue skips the remaining statements in the current loop iteration. It can keep a loop shallow when a value should be ignored, but avoid stacking many continue conditions because the main path becomes difficult to see. Validate or filter a collection before iterating when that produces simpler code. The example prints only positive values. Further guidance Before running a loop, identify the value that changes and the condition that eventually stops it. Check empty collections and one-item collections as well as the normal case. Prefer foreach when iterating a collection, and keep early exits easy to understand. Practice task: Create a fresh example for continue. Predict the result before running it, then change one input and explain why the result changes. Test a normal case and one boundary or invalid case where it applies. Compare your output with the example and note one rule you would use in a real project.

Code examples

continue

PHP

foreach ([-2, 3, 0, 5] as $value) {
    if ($value <= 0) {
        continue;
    }
    echo $value, ' ';
}

Expected output

3 5

Key points

Skip the rest of one iteration and move to the next.
Identify the loop state and a clear termination condition.
Test empty and one-item inputs as well as the normal case.
