php foreach 語法上是不可以同時遍歷2個數組的，只能遍歷一個數組。程式碼如下：<?php$array1 = array(0=>"a",1=>"b");foreach($array1 as $key1=>$value1){ echo $key1.":".$value1."<br>";}?>不過，如果這2個數組有相同的鍵名的話，可以同時遍歷。程式碼如下：<?php$array1 = array(0=>"a",1=>"b");$array2= array(0=>"c",1=>"d");foreach($array1 as $key1=>$value1){ echo "陣列1 ".$key1.":".$value1."<br>"; echo "陣列2 ".$key1.":".$array2[$key1]."<br>";}
