i是代表几，例如是1的话。那就是运行第一行代码。case1;如果是2的话，case:2其他的都一样。
这里如果 $i 等于 0，php 将执行所有的 print 语句,如果 $i 等于 1，php 将执行后面两条 print 语句。只有当 $i 等于 2 时，才会得到“预期”的结果――只显示“i equals 2”。所以，别忘了 break 语句就很重要（即使在某些情况下故意想避免提供它们时）。在 switch 语句中条件只求值一次并用来和每个 ...

是指从i=1开始、执行选择分支语句switch(1)，输出case1:后面的结果，break跳出；然后i=2、i=3轮着输出。（如果不存在case2、3则直接跳出或者输出“default”）当i=4时>3，跳出for循环。
State I, the “Turn” state, allows two signals to pass from port 1 to port 4, and from port 3 to port 2. In State II, the “Thru” state, the signal is connected from port 1 to 2 and from port 3 to 4. Chan et al., (2009) realized 4 × 4 L-shaped and 4 × 4 cross...
