Detailed explanation of while(list($key,$val)=each($result)) in php to obtain array_PHP tutorial

In php, while(list($key,$val)=each($result)) reads the $result array value and loops to obtain the array content and assigns it to $key, $val.

Example

echo "

";

The code is as follows

代码如下	复制代码
echo "类CAR中的所有方法名为："; echo " "; $result=get_class_methods("CAR"); //获取类CAR中的方法名get_class_methods() while(list($key,$val)=each($result))   //循环获取数组内容 {   echo "方法$key=>$val";   echo " "; }

Copy code

echo "All methods in class CAR are named:";

$result=get_class_methods("CAR"); //Get the method name in class CAR get_class_methods()

while(list($key,$val)=each($result)) //Loop to obtain the contents of the array

{ echo "Method $key=>$val"; echo "

"; } The list() function assigns values ​​to a set of variables using elements in the array.

Note that, similar to array(), list() is actually a language construct, not a function
