我正在尝试创建一个Ajax/Php表单。服务器端的工作非常完美，打印效果正是我所期望的。在这个php文件的"版本"中，我直接创建了ajaxArray。

$ajaxArray = array(0 => array(from => "01/01/2010",
                              to => "01/01/2011",
                              amount => 1000.00),
                   1 => array(from => "01/01/2011",
                              to => "01/01/2012",
                              amount => 100.00),
                   2 => array(from => "01/01/2012",
                              to => "01/01/2013",
                              amount => 100.00)
);
$returnAjax = array();
foreach ($ajaxArray as $value){
    //... Here we do some operations and push result into $returnAjax ...   
} 
print "<pre>";
print_r($returnAjax);
print "</pre>";

我的问题是当我试图通过Ajax传递ajaxArray时。

客户端：

var ajaxArray = //Some function to create the array
ajaxData = {ajaxArray: JSON.stringify(ajaxArray)};
console.log(ajaxData) //OK, the ajaxArray have the right values  
$.ajax({
    type: 'POST',
    url: '..url-to-php-file',
    data: ajaxData,
    dataType: 'json',
    success: function (data) {
        console.log(data);
    }
});

这是console.log(ajaxData):

ajaxArray: "[{"from":"01/01/2010","to":"01/01/2011","amount":"1000.00"},{"from":"01/01/2011","to":"01/01/2012","amount":"100.00"},{"from":"01/01/2012","to":"01/11/2013","amount":"100.00"}]"

服务器端。这是同一.php文件的更改版本。如您所见，$ajaxArray从$_POST获取值，但$returnAjax返回空响应

 $ajaxArray = json_decode($_POST['ajaxArray']);
 $returnAjax = array();
 foreach ($ajaxArray as $value){
     /*... Here we do the same operations as 
     before and push result into $returnAjax ...*/
 }                  
 return json_encode($returnAjax);

当值通过Ajax传递或出现其他问题时，foreach循环似乎不起作用。

提前感谢

编辑：在意大利语中，Da=from，A=to，Importo=金额

这是var_dump($_POST['ajaxArray']); 的控制台日志

string(218) "[{"Da":"01/01/2010","A":"01/01/2011","Movimento":"A","Importo":"1000.00"},{"Da":"01/01/2011","A":"01/01/2012","Movimento":"D","Importo":"100.00"},{"Da":"01/01/2012","A":"26/04/2014","Movimento":"D","Importo":"100.00"}]"

这是var_dump( json_decode($_POST['ajaxArray']) ) 的控制台日志

string(218) "[{"Da":"01/01/2010","A":"01/01/2011","Movimento":"A","Importo":"1000.00"},{"Da":"01/01/2011","A":"01/01/2012","Movimento":"D","Importo":"100.00"},{"Da":"01/01/2012","A":"26/04/2014","Movimento":"D","Importo":"100.00"}]"
array(3) {
  [0]=>
  object(stdClass)#5 (4) {
    ["Da"]=>
    string(10) "01/01/2010"
    ["A"]=>
    string(10) "01/01/2011"
    ["Movimento"]=>
    string(1) "A"
    ["Importo"]=>
    string(7) "1000.00"
  }
  [1]=>
  object(stdClass)#6 (4) {
    ["Da"]=>
    string(10) "01/01/2011"
    ["A"]=>
    string(10) "01/01/2012"
    ["Movimento"]=>
    string(1) "D"
    ["Importo"]=>
    string(6) "100.00"
  }
  [2]=>
  object(stdClass)#7 (4) {
    ["Da"]=>
    string(10) "01/01/2012"
    ["A"]=>
    string(10) "26/04/2014"
    ["Movimento"]=>
    string(1) "D"
    ["Importo"]=>
    string(6) "100.00"
  }
}

在第一个例子中，您使用的是关联数组，但是客户端的返回是json_edecoded，关联数组被转换为Objects。我怀疑你在循环中没有考虑到这一点。

$returnAjax = array();
foreach ($ajaxArray as $value){
    // not this - $value['from'];
    // this
    $value->from;   
}
