我有这个脚本和它的作品，而不是如我所料。我需要用型动物的名称赋值的数组，现在都$常用3 []被命名为勇敢

i have this script and it works, but not as i expected. I need to assign an array of values with differents names, now all $arr[] are named "valor"

{"valor":"20"},{"valor":"50"}

我需要

{"valor1":"20"},{"valor2":"50"}

剧本

    $query = mysql_query("SELECT valor FROM grafico") or die(mysql_error());

    $arr = array();
    while($row = mysql_fetch_assoc($query)) {
        $arr[] = $row;
    }
    echo json_encode($arr);


in ajax

    <script type="text/javascript">
       jQuery(document).ready(function(){
          jQuery("button").click(function(){

             jQuery.ajax({
                url: "chart.php",
                dataType: "json", 
                success: function(json){
                   var msg = "Nome: " + json.valor1+ "\n";
                   msg += "Sobrenome: " + json.valor2 + "\n";

                   alert(msg);
                }
             });
          });
       });

       </script>

问题是：我需要创造，创造独有名称的循环，因为值1，值2，值3

the problem is: I need to create a loop that create uniques names, as value1, value2, value3

喜欢

$改编['valor1'] =伊万德罗;

我尝试了LOOP-的，但我得到的内存错误

i tried a loop- for, but i get an error of memory

感谢

推荐答案

试试这个：

$query = mysql_query("SELECT valor FROM grafico") or die(mysql_error());

$arr = array();
$i = 1;
while($row = mysql_fetch_assoc($query)) {
    $arr[] = array("valor{$i}" => $row["valor"]);
    ++$i;
}
echo json_encode($arr);

应该工作。另外，如果你想它，所以它的工作原理与目前的回调修改 $ ARR [] = 线以下内容：

    $arr["valor{$i}"] = $row["valor"];
