foreach語句用於迴圈遍曆數組。
每進行一次迴圈，當前數組元素的值就會被賦值給 value 變數（數組指標會逐一地移動） - 以此類推

foreach($array as $key)
{
if(xxxx)
{
break; //break 會終止迴圈
}
if(zzz)
{
continue; //continue 會終止本次迴圈，此刻會進入下一個迴圈；
}

<?php
$team = array('lk','ok');
$book = array('linux伺服器配置與管理',$team);
foreach($book as $k=>$val) //意思是for $book each $value( as )
if( is_array($val) ) foreach( $val as $value) echo $value.'<br />';
else echo $k.'=>'.$val.'<br />';
