php - 如何在php数组中存储字符串变量

Question

$matrix=array($_SESSION['review_buffer_name'],$_SESSION['review_buffer_mail'],$_SESSION['review_buffer_comment']);

上面这行代码是在WHILE循环中，所以它存储了多条数组记录。这样存储记录的方式正确吗？。我们如何访问矩阵的每条记录和值？

$matrix 应该存储多行数组...问题是当我访问 $matrix[2] 然后它给出数组的第二个值...而不是数组的第二个记录

你可以试试:

//Before while loop declare the array variable
$matrix = array();

While(your condition){
    $matrix[] = array(
           $_SESSION['review_buffer_name'],
           $_SESSION['review_buffer_mail'],
           $_SESSION['review_buffer_comment']
   );
}

//To access array:

print_r($matrix[0]); //print_r whole first row. (array start from 0)
echo $matrix[0][0]; //echo single data that first row's first data

Or you can set index as name like:

//Before while loop declare the array variable
$matrix = array();

While(your condition){
    $matrix[] = array(
           'review_buffer_name'=>$_SESSION['review_buffer_name'],
           'review_buffer_mail'=>$_SESSION['review_buffer_mail'],
           'review_buffer_comment'=>$_SESSION['review_buffer_comment']
    );
    }

//Then access array:

print_r($matrix[0]); //print_r whole first row. (array start from 0)
echo $matrix[0]['review_buffer_name']; // first row's first data
