php 的 list 函示可以把陣列中的值轉換為變數。
語法:
list(var1,var2...)
其中至少要填第一個的值,第二個之後則是看要放多少變數去取得陣列內的值。
範例 1:
$my_array = array("Dog","Cat","Horse"); list($a, $b, $c) = $my_array; echo "I have several animals, a $a, a $b and a $c."; //輸出 I have several animals, a Dog, a Cat and a Horse.
範例 2:只用了 a 和 c 的變數
$my_array = array("Dog","Cat","Horse"); list($a, , $c) = $my_array; echo "Here I only use the $a and $c variables."; //輸出 Here I only use the Dog and Horse variables.
