使用PHP从MySql获取JSON格式到javascript

我想使用PHP从SQL数据库中获取json格式

下面是mySql数据库的一个捕获

data.php

<?php  include("include/connexion.php");
$requete = "SELECT * from statistika";
$resultat = mysql_query( $requete ) or die( mysql_error() );
$rows = array(); 
$total_vue = 0;

<?php
 include("data.php");
 echo  json_encode($rows);
?>

json_encode.php

<?php  include("include/connexion.php");
$requete = "SELECT * from statistika";
$resultat = mysql_query( $requete ) or die( mysql_error() );
$rows = array(); 
$total_vue = 0;

<?php
 include("data.php");
 echo  json_encode($rows);
?>

现在我想将JSON格式传递给javascript，我正在使用以下代码

var foo = {};
foo.toString = function () { return <?php echo json_encode($rows);?> };
document.write(foo.toString);

我不希望

函数（）{return

出现在输出中！！！

有什么提示吗

谢谢。

在JS代码中更改这一行

从

foo.toString=function（）{return}；

到

foo.toString=''；

var foo={}；
foo.toString=函数（）{return}；
document.write（foo（））；

您正在创建foo as函数，因此像这样调用您将只得到json。

首先，我建议您不要将

javascript

和

php

代码混合在一个文件中。这是一种非常糟糕的样式。否则，在某一时刻，您将得到一些糟糕的spagetti代码。您最好从ajax调用中获得这些json数据。只需分而治之，正如他们所说的。谢谢，我想用amcharts库中的数据…你以前用过这个库吗？

foo.toString = function () { return <?php echo json_encode($rows);?> };

foo.toString = '<?php echo json_encode($rows);?>';

var foo = {};
foo.toString = function () { return <?php echo json_encode($rows);?> };
document.write(foo());
