.php文件的字符编码错误 [英] Character encoding error for .php file
问题描述
为MarkersController.php创建了一个返回json的路由，但是当我导航到路由时，出现以下错误：
HTML文档的字符编码没有被宣布。如果文档包含US-ASCII范围之外的字符，则该文档将在某些浏览器配置中呈现乱码文本。必须在文档或传输协议中声明页面的字符编码。
我的路线如下所示：
$ app-> get（'/ markers /？'，function（）use（$ app）{
$ controller = new UF\MarkersController（$ app）;
return $ controller-> getMarkersJSON（）;
}）;
MarkersController.php
<！DOCTYPE html>
< html lang =en>
< head>
{％include'components / head.html'％}
< / head>
< body>
<？php
include（'DB_INFO.php'）;
函数getMarkersJSON（）{
//打开到MySQL服务器的连接。
$ connection = mysqli_connect（$ server，$ username，$ password）;
$ b $ if（！$ connection）{
die（'Not connected：'。mysqli_error（））;}
//设置活动的MySQL数据库。
$ db_selected = mysqli_select_db（$ database，$ connection）;
if（！$ db_selected）{
die（'can not use db：'。mysqli_error（））;}
//选择全部标记表中的行。
$ query =SELECT * FROM tester WHERE 1;
$ result = mysqli_query（$ connection，$ query）;
if（！$ result）{
die（'Invalid query：'。mysqli_error（））;
}
$ markers = array（）;
while（$ row = mysqli_fetch_assoc（$ result））{
//假设lat是测试仪表中的列名称。如果需要请更改它。
$ lat = $ rows ['lat'];
//假设lng是测试仪表中的列名称。如果需要请更改它。
$ lng = $ rows ['lng'];
$ markers = array（'lat'=> $ lat，'lng'=> $ lng）;
}
echo json_encode（$ markers）;
}

< / body>
< / html>
您是否有Content-Type定义。 HTML？
如果答案是否定的，试着把
< meta http-equiv =Content-Type内容=text / html; charset = [your-charset]/>
放入您的head.html
Have made a route for MarkersController.php which returns json, but when i navigate to the route I get the following error:
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.
My route is as follows:
$app->get('/markers/?', function () use ($app) {
$controller = new UF\MarkersController($app);
return $controller->getMarkersJSON();
});
MarkersController.php
<!DOCTYPE html>
<html lang="en">
<head>
{% include 'components/head.html' %}
</head>
<body>
<?php
include('DB_INFO.php');
function getMarkersJSON(){
// Opens a connection to a MySQL server.
$connection = mysqli_connect($server, $username, $password);
if (!$connection) {
die('Not connected : ' . mysqli_error());}
// Sets the active MySQL database.
$db_selected = mysqli_select_db($database, $connection);
if (!$db_selected) {
die('Can\'t use db : ' . mysqli_error());}
// Selects all the rows in the markers table.
$query = "SELECT * FROM tester WHERE 1";
$result = mysqli_query($connection, $query);
if (!$result) {
die('Invalid query: '. mysqli_error());
}
$markers = array();
while ($row = mysqli_fetch_assoc($result)) {
//Assuming "lat" is column name in tester table. Please change it if required.
$lat= $rows['lat'];
//Assuming "lng" is column name in tester table. Please change it if required.
$lng= $rows['lng'];
$markers = array('lat' => $lat, 'lng' => $lng);
}
echo json_encode($markers);
}
?>
</body>
</html>
Do you have Content-Type definition into your head.html? If the answer is no, try to put
<meta http-equiv="Content-Type" content="text/html;charset=[your-charset]" />
into your head.html
