PHP“继续”停止foreach循环

This seems like a very stupid question, but without making any changes to the server.. the continue function in PHP seems to have started working incorrectly.

For example:

function contTest(){
    $testers = array(1, 3, 4, 5);
    foreach($testers as $test){
        echo "Got here<br>";
        continue;
        echo $test."<br>";
    }
}

Outputs:

Got here
Got here
Got here
Got here

Whereas:

function contTest(){
    $testers = array(1, 3, 4, 5);
    foreach($testers as $test){
        echo "Got here<br>";
        echo $test."<br>";
    }
}

Ouputs:

Got here
1
Got here
3
Got here
4
Got here
5

I have used this function before and it did not seem to have this effect. Any ideas? Like I said, nothing on the server has changed so the PHP version is the same.

    I don’t know what effect you want, but this example is working correctly. continue needs to break current iteration and go to the next without executing code below this operator. And this function works in this case all the time since PHP 4.
