Question

require_once("conect.php");
$sqlString="SELECT * FROM articles;";
$response = array();
$posts = array();
$query=mysql_query($sqlString) or die (mysql_error());
    while ($row=mysql_fetch_array($query)){
        $title =$row["title"];
        $author =$row["author"];
        $article =$row["article"];
        $posts[] = array('title'=> $title, 'author'=> $author, 'article'=> $article);

    }
$response['posts'] = $posts;

$fp = fopen('json\results.json', 'w');
fwrite($fp, json_encode($response));
fclose($fp);`

...结果

{"posts":[{"title":"tatoo","author":"lakmal","article":"A tattoo is a ."},  
{"title":"dog","author":"lakmal","article":"The domestic dog"},  
{"title":"cat","author":"chamikara","article":"The domestic"},  
{"title":"Automobile","author":"lakmal","article":"An automobile"}]}

我希望它保存为jsonobject

Answer 1

$json_data = json_encode($response);
$filename ="yourfilename.json";
header('Content-type: application/json');
header('Content-Disposition: attachment; filename='.$filename);
echo $json_data ;

这就是你要找的东西。

Answer 2

`$ title，'author'=＆gt; $ author，'article'=＆gt; $文章）;

        }
    $response = $posts;

    $fp = fopen('results.json', 'w');
    fwrite($fp, json_encode($response));
    fclose($fp);

＆GT;`

<?php
        require_once("conect.php");
        $jsonData="[{";
        $sqlString="SELECT * FROM articles;";
        $query=mysql_query($sqlString) or die (mysql_error());
            while ($row=mysql_fetch_array($query)){
                $title =$row["title"];
                $author =$row["author"];
                $article =$row["article"];
                $jsonData.='"title":"'.$title.'","author":"'.$author.'","article"'.$article.'"},';      
                $jsonData.="{";         
            }
        $jsonData = chop ($jsonData, ",");
        $jsonData.="]";


        $fp = fopen('results.json', 'w');
        fwrite($fp,json_encode($jsonData));
        fclose($fp) 

?>`
