continue 在循环结构用用来跳过本次循环中剩余的代码并开始执行下一次循环。
continue 接受一个可选的数字参数来决定跳过几重循环到循环结尾。
while (list ($key, $value) = each ($arr)) {
if (!($key % 2)) { // skip odd members
continue;
}
do_something_odd ($value);
}
$i = 0;
while ($i++ < 5) {
echo "Outer<br>\n";
while (1) {
echo " Middle<br>\n";
while (1) {
echo " Inner<br>\n";
continue 3;
}
echo "This never gets output.<br>\n";
}
echo "Neither does this.<br>\n";
