Detailed explanation of PHP assignment to array (two-dimensional array assignment)_PHP tutorial

Array assignment in PHP is very simple. If it is a one-dimensional array assignment, it is simpler than a two-dimensional array or a multi-dimensional array. Now I will introduce to you various examples of array assignment. Friends who need to know can refer to it.

What about PHP array assignment? As follows:

Example 1, one-dimensional array assignment

The code is as follows

代码如下	复制代码
$My_array=array()；  $My_array[]=”www”   $My_array[]=”helpphp”;   $My_array[]=”cn”;

Copy code

$My_array=array();

代码如下	复制代码
unset($My_array[0]; unset($My_array);

$My_array[]=”www”

$My_array[]=”helpphp”;
$My_array[]=”cn”;

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

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;     }

Destroy array

The code is as follows

Copy code

unset($My_array[0];

unset($My_array); Example 2, two-dimensional array assignment

The code is as follows

Copy code

$data_array=array($total,2); //where $datarows is the number of records obtained from the query $data_array[$i][2]=$Area;//Error message: Cannot use a scalar value as an array

The specific cycle is as follows

The code is as follows

Copy code

$i=0; while($result=$db->fetch_array($query)) { $Area=$result["Area"]; $data_array[$i][2]=$Area; //Error! $i=$i+1;  } http://www.bkjia.com/PHPjc/628683.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/628683.htmlTechArticleArray assignment in php is very simple.
