使用 PHP 从 MySql 到 javascript 获取 JSON 格式

Question

我想使用 PHP

从我的 SQL 数据库中获取 json 格式

这里是 mySql 数据库的捕获

data.php

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

这里是php获取数据的代码

while( $data = mysql_fetch_assoc( $resultat ) ) {
  $total_vue+=$data['temps'];
   $rows[] = array(
    "date" =>  strtotime( $data['date']) * 1000,
    "value" => $data[ 'temps' ]
  );
}
?>

json_encode.php

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

json_encode内容有效，成功获取json格式

[{"date":1439769600000,"value":"5"},{"date":1439787600000,"value":"12"},{"date":1439806631000,"value":"8"},{"date":1439821320000,"value":"18"},{"date":1439919642000,"value":"6"},{"date":1439889752000,"value":"2"},{"date":1439893260000,"value":"20"},{"date":1439906400000,"value":"9"},{"date":1429308000000,"value":"15"},{"date":1421535600000,"value":"12"},{"date":1413583200000,"value":"18"},{"date":1405634400000,"value":"6"},{"date":1439828640000,"value":"14"},{"date":1439935200000,"value":"19"},{"date":1439863200000,"value":"12"},{"date":1439884800000,"value":"18"},{"date":1439917200000,"value":"26"},{"date":1439920800000,"value":"4"},{"date":1439904320000,"value":"0"},{"date":1439907420000,"value":"1"},{"date":1439907428000,"value":"1"},{"date":1439907434000,"value":"3"},{"date":1439907437000,"value":"1"},{"date":1439907447000,"value":"8"},{"date":1439907452000,"value":"3"},{"date":1439907459000,"value":"5"},{"date":1439907469000,"value":"8"},{"date":1439907482000,"value":"10"},{"date":1439907507000,"value":"21"},{"date":1439907510000,"value":"1"},{"date":1439907519000,"value":"7"},{"date":1439907526000,"value":"5"},{"date":1439907547000,"value":"18"},{"date":1439907557000,"value":"8"},{"date":1439907560000,"value":"1"},{"date":1439907576000,"value":"3"},{"date":1439907581000,"value":"3"},{"date":1418857200000,"value":"300"},{"date":1426633200000,"value":"450"},{"date":1434578400000,"value":"500"},{"date":1424214000000,"value":"600"}]

现在我想将 JSON 格式传递给 javascript ，我正在使用此代码

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

问题是打印时 foo.toString 我得到这个

function () { return [{"date":1439769600000,"value":"5"},{"date":1439787600000,"value":"12"},{"date":1439806631000,"value":"8"},{"date":1439821320000,"value":"18"},{"date":1439919642000,"value":"6"},{"date":1439889752000,"value":"2"},{"date":1439893260000,"value":"20"},{"date":1439906400000,"value":"9"},{"date":1429308000000,"value":"15"},{"date":1421535600000,"value":"12"},{"date":1413583200000,"value":"18"},{"date":1405634400000,"value":"6"},{"date":1439828640000,"value":"14"},{"date":1439935200000,"value":"19"},{"date":1439863200000,"value":"12"},{"date":1439884800000,"value":"18"},{"date":1439917200000,"value":"26"},{"date":1439920800000,"value":"4"},{"date":1439904320000,"value":"0"},{"date":1439907420000,"value":"1"},{"date":1439907428000,"value":"1"},{"date":1439907434000,"value":"3"},{"date":1439907437000,"value":"1"},{"date":1439907447000,"value":"8"},{"date":1439907452000,"value":"3"},{"date":1439907459000,"value":"5"},{"date":1439907469000,"value":"8"},{"date":1439907482000,"value":"10"},{"date":1439907507000,"value":"21"},{"date":1439907510000,"value":"1"},{"date":1439907519000,"value":"7"},{"date":1439907526000,"value":"5"},{"date":1439907547000,"value":"18"},{"date":1439907557000,"value":"8"},{"date":1439907560000,"value":"1"},{"date":1439907576000,"value":"3"},{"date":1439907581000,"value":"3"},{"date":1418857200000,"value":"300"},{"date":1426633200000,"value":"450"},{"date":1434578400000,"value":"500"},{"date":1424214000000,"value":"600"}]

我不希望 function () { return 出现在输出中！！！

有什么提示吗？

谢谢。

Answer 1

在您的 JS 代码中更改这一行

来自

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

到

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

Answer 2

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

您正在创建 foo 作为函数，所以像这样调用您只会得到 json。
