(PHP 4, PHP 5, PHP 7)

continue is used in the loop structure to skip the remaining code in this loop and start executing the next loop when the condition evaluates to true.

Note: Note that in PHP the switch statement is considered a loop structure that can use continue.

continue accepts an optional numeric parameter to determine how many loops to skip to the end of the loop. The default value is 1, which jumps to the end of the current loop.

\n";
    while (1) {
        echo "Middle
\n";
        while (1) {
            echo "Inner
\n";
            continue 3;
        }
        echo "This never gets output.
\n";
    }
    echo "Neither does this.
\n";
}
?>

Omitting the semicolon after continue can cause confusion. The following example shows how not to do this.

The desired result is:

0
1
3
4

But the actual output is:

2
