在for循环中创建Json数组-PHP [英] Create a Json array in a for loop - php

问题描述

<?php
include '../connection.php';

$sql="SELECT userid,name,batch FROM dbusers";
$results=mysql_query($sql) or die("Cannot execute query");
$count=mysql_num_rows($results);
$arr=array();
for($i=0; $i < $count; $i++){
$rows=mysql_fetch_array($results);
//What to put here ?
}
json_encode($arr);

?>

这是我的php代码.我想问一下要放入for循环中的内容，以便可以在php中创建一个数组数组.内部数组将以userid，name和batch作为其元素.

This is my php code. I want to ask what to put inside the for loop so that I can create a an array of array in php. The inner array will have userid, name and batch as its elements .

推荐答案

在这里放什么?

$ arr [] = $ rows;

完整代码

<?php
include '../connection.php';

$sql="SELECT userid,name,batch FROM dbusers";
$results=mysql_query($sql) or die("Cannot execute query");
$count=mysql_num_rows($results);
$arr=array();
for($i=0; $i < $count; $i++){
    $rows=mysql_fetch_array($results, MYSQL_ASSOC);//use MYSQL_ASSOC so you wouldn't have duplicate data
    $arr[] = $rows;
}
$json = json_encode($arr);

?>
