The break statement is used in the loop body or switch, which means to jump out of the current loop. If break appears in switch, it jumps out of the current switch statement body of switch. In the for loop, you jump out of the current loop. And continue is this loop, skip the statements after this loop and continue with the next loop.
Eg: 99 multiplication table

<code><span>for</span>(<span>$i</span>=<span>1</span>;<span>$i</span><<span>10</span>;<span>$i</span>++){
        <span>for</span>(<span>$j</span>=<span>1</span>;<span>$j</span><=<span>$i</span>;<span>$j</span>++){
            <span>if</span>(<span>$j</span>==<span>3</span>)
                <span>//会跳过j=3的算式</span><span>continue</span>;
            <span>echo</span><span>$i</span>.<span>'x'</span>.<span>$j</span>.<span>'='</span>.<span>$i</span>*<span>$j</span>.<span>'    '</span>;
        }
        <span>echo</span><span>"<br/>";
    }</code>

Pulse result: When j=3, this loop will end and the next loop will continue. The column i*3 will not appear

<code><span>for</span>(<span>$i</span>=<span>1</span>;<span>$i</span><<span>10</span>;<span>$i</span>++){
        <span>for</span>(<span>$j</span>=<span>1</span>;<span>$j</span><=<span>$i</span>;<span>$j</span>++){
            <span>if</span>(<span>$j</span>==<span>3</span>)
                <span>break</span>;
            <span>echo</span><span>$i</span>.<span>'x'</span>.<span>$j</span>.<span>'='</span>.<span>$i</span>*<span>$j</span>.<span>'    '</span>;
        }
        <span>echo</span><span>"<br/>";
    }</code>

Result: When the loop reaches j=3 , will jump out of this loop, i*3 and the following columns will not be executed, so only the two columns i*1 and i*2 will appear in the result
