我有一个php文件选择表中的所有行,我想将结果内容存储在www /目录中的文件中,就像我可以解析该name.json文件并使用jackson库在Android中显示其内容。 这是我的php文件:
<?php header('Content-type: application/json');
/*
* Following code will list all the surveys
*/
// array for JSON response
$response = array();
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// get all surveys from surveys table
$result = mysql_query("SELECT * FROM surveys") or die(mysql_error());
// check for empty result
if (mysql_num_rows($result) > 0) {
// looping through all results
// surveys node
$response["surveys"] = array();
while ($row = mysql_fetch_array($result)) {
// temp user array
$survey = array();
$survey["id_survey"] = $row["id_survey"];
$survey["question_survey"] = $row["question_survey"];
$survey["answer_yes"] = $row["answer_yes"];
$survey["answer_no"] = $row["answer_no"];
// push single survey into final response array
array_push($response["surveys"], $survey);
}
// success
$response["success"] = 1;
// echoing JSON response
echo json_encode($response);
} else {
// no surveys found
$response["success"] = 0;
$response["message"] = "No surveys found";
// echo no users JSON
echo json_encode($response);
}
?>
所以:php file =&gt;执行=&gt;将结果存储在file =&gt;中解析该文件并在Android中显示。

如果您想将JSON写入文件,只需添加:
file_put_contents( "filename.json", json_encode($response) );
旁边或代替echo
