获取所有mysql选定的行到一个数组中 [英] Get all mysql selected rows into an array

问题描述

我想知道 php 中是否有一个函数可以让我将所有选定的数据放入一个数组中.目前我正在使用 mysql_fetch_array 并且正如我在手册中所阅读的那样，该函数不会获取表中的每条记录.

I am wondering if there a function in php that can allow me put all my selected data in an array .Currently i am using mysql_fetch_array and as i have read in the manual,that function won't fetch every record in the table.

$result = mysql_query("SELECT * FROM $tableName");            
$array = mysql_fetch_array($result);

  echo json_encode($array);

推荐答案

出于性能和安全目的，我建议使用 MySQLi 或 MySQL PDO，但要回答这个问题:

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:

while($row = mysql_fetch_assoc($result)){
     $json[] = $row;
}

echo json_encode($json);

如果你切换到 MySQLi，你可以这样做:

If you switched to MySQLi you could do:

$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);

$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );
