Question

Answer 1

break ends a loop completely, continue just shortcuts the current iteration and moves on to the next iteration.

while ($foo) {   <--------------------┐
    continue;    --- goes back here --┘
    break;       ----- jumps here ----┐
}                                     |
                 <--------------------┘

这样做就是为了:

while ($droid = searchDroids()) {
    if ($droid != $theDroidYoureLookingFor) {
        continue; // ..the search with the next droid
    }

    $foundDroidYoureLookingFor = true;
    break; // ..off the search
}

Answer 2

打破你身边的圈子,从循环的下一个周期开始。

例:

$i = 10;
while (--$i)
{
    if ($i == 8)
    {
        continue;
    }
    if ($i == 5)
    {
        break;
    }
    echo $i . "
";
}

Answer 3

BREAK:

break ends execution of the current for, foreach, while, do-while or switch structure.

CONTINUE:

continue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.

因此,根据你的需要,你可以把目前由你法典执行的立场重新定位到目前nes取的不同水平。

另见,关于细列细目的说明,请举几个例子。

Answer 4

记录:

Note that in PHP the switch statement is considered a looping structure for the purposes of continue.

Answer 5

休息时间是从假发言中抽出的,但继续停留在具体情况下,然后继续停留在最后。

for($i=0; $i<10; $i++){
    if($i == 5){
        echo "It reach five<br>";
        continue;
    }
    echo $i . "<br>";
}

echo "<hr>";

for($i=0; $i<10; $i++){
    if($i == 5){
         echo "It reach end<br>";
         break;
    }
    echo $i . "<br>";
}

希望能帮助u;

Answer 6

在住宿结构中继续使用,以绕过目前休息时间,并在情况评估中继续实施,然后在下一个周期开始。

停工停工停工,停工或开关。

分离接受选择性的计数论点,它告诉它,有多少封顶的封闭结构将被打破。

我在此没有写任何东西。仅是PHP手册的改动说明。

Version Description

7.0.0 - continue outside of a loop or switch control structure is now detected at compile-time instead of run-time as before, and triggers an E_COMPILE_ERROR.

5.4.0   continue 0; is no longer valid. In previous versions it was interpreted the same as continue 1;.

5.4.0   Removed the ability to pass in variables (e.g., $num = 2; continue $num;) as the numerical argument.
