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"}]}
我希望它另存为 JSON 对象
$json_data = json_encode($response);
$filename ="yourfilename.json";
header('Content-type: application/json');
header('Content-Disposition: attachment; filename='.$filename);
echo $json_data ;
这是你要找的吗？
' $title， 'author'=
> $author， 'article'=> $article(;
}
$response = $posts;
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($response));
fclose($fp);
？>'
将
mysql 结果作为对象获取。不要费心转换它。

mysql_fetch_object
我找到了答案
<?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)
?>`
