Difference between break and continue in PHP?
回答by deceze
breakends a loop completely, continuejust shortcuts the current iteration and moves on to the next iteration.
break完全结束一个循环，continue只是缩短当前迭代并移动到下一次迭代。
while ($foo) { <--------------------┐
continue; --- goes back here --┘
break; ----- jumps here ----┐
} |
<--------------------┘
This would be used like so:
这将像这样使用：
while ($droid = searchDroids()) {
if ($droid != $theDroidYoureLookingFor) {
continue; // ..the search with the next droid
}
$foundDroidYoureLookingFor = true;
break; // ..off the search
}

break exits the loop you are in, continue starts with the next cycle of the loop immediatly.
break 退出您所在的循环， continue 立即开始循环的下一个循环。
Example:
例子：
$i = 10;
while (--$i)
{
if ($i == 8)
{
continue;
}
if ($i == 5)
{
break;
}
echo $i . "\n";
}
will output:
将输出：
9
7
6

break ends execution of the current for, foreach, while, do-while or switch structure.
break 结束当前 for、foreach、while、do-while 或 switch 结构的执行。
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.
continue 在循环结构中用于跳过当前循环迭代的其余部分，并在条件评估和下一次迭代开始时继续执行。
So depending on your need, you can reset the position currently being executed in your code to a different level of the current nesting.
因此，根据您的需要，您可以将代码中当前正在执行的位置重置为当前嵌套的不同级别。

For the Record:
作为记录：
Note that in PHP the switchstatement is considered a looping structurefor the purposes of continue.
请注意，在 PHP中，出于continue的目的，switch语句被视为循环结构。

break used to get out from the loop statement, but continue just stop script on specific condition and then continue looping statement until reach the end..
break 用于退出循环语句，但继续只是在特定条件下停止脚本，然后继续循环语句直到到达结束..
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>";
}
Hope it can help u;

Break ends the current loop/control structure and skips to the end of it, no matter how many more times the loop otherwise would have repeated.
Break 结束当前循环/控制结构并跳到它的末尾，不管循环会重复多少次。
Continue skips to the beginning of the next iteration of the loop.
继续跳到循环的下一次迭代的开始。

'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.
'continue' 在循环结构中用于跳过当前循环迭代的其余部分，并在条件评估和下一次迭代开始时继续执行。
'break' ends execution of the current for, foreach, while, do-while or switch structure.
'break' 结束当前 for、foreach、while、do-while 或 switch 结构的执行。
break accepts an optional numeric argument which tells it how many nested enclosing structures are to be broken out of.
break 接受一个可选的数字参数，它告诉它要打破多少嵌套的封闭结构。

breakwill stop the current loop (or pass an integer to tell it how many loops to break from).
break将停止当前循环（或传递一个整数来告诉它要中断多少个循环）。
continuewill stop the current iteration and start the next one.
continue将停止当前迭代并开始下一个迭代。
回答by cspolton
breakwill exit the loop, while continuewill start the next cycle of the loop immediately.
break将退出循环，whilecontinue将立即开始循环的下一个循环。

I am not writing anything same here. Just a changelog note from PHP manual.
我在这里没有写任何相同的东西。只是 PHP 手册中的变更日志说明。
Changelog for continue

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.
