在php中数组赋值很简单,如果是一维数组赋值比二维数组或多维数组更简单,下面我来给各位同学介绍给数组赋值各种实例介绍,有需要了解的朋友可参考。

PHP数组赋值呢?如下:

例1,一维数组赋值

 代码如下 复制代码

$My_array=array(); 
$My_array[]=”www”  
$My_array[]=”helpphp”;  
$My_array[]=”cn”;


销毁数组

 代码如下 复制代码

unset($My_array[0];
unset($My_array); 


例2,二维数组赋值

 代码如下 复制代码

$data_array=array($total,2);//其中$datarows为查询得到的记录数 
$data_array[$i][2]=$Area;//提示错误:Cannot use a scalar value as an array 


具体的循环如下

 代码如下 复制代码

$i=0;
 while($result=$db->fetch_array($query))
 {  $Area=$result["Area"];
 $data_array[$i][2]=$Area; //出错! 
$i=$i+1;    
}
