我希望在PHP中打破外部for/foreach循环.

这可以在ActionScript中完成,如下所示:

top : for each(var i:MovieClip in movieClipArray)
{
    for each(var j:String in nameArray)
    {
        if(i.name == j) break top;
    }
}

什么是PHP等价物？

在我工作的许多项目中,我发现我有嵌套for循环(我将专注于PHP实现,但也适用于javascript)采用这种通用形式:

$array1 = array(........);
$count1 = count($array1);

$invalidState = false;//An invalid state will be looked for in the innermost loop, and if found, break all the loops

for($i = 0; $i < $count1; $i++) {
    //parsing, then another loop
    $array2 = explode("needle", $array1[$i]);
    $count2 = count($array2);
    for($j = 0; $j < $count2; $j++) {
        //parsing, then sometimes even another another loop
        $array3 = explode("different-needle", $array2[$j]);
        $count3 = count($array3);
        for($k = 0; $k < $count3; $k++) {
            //check for …
