Question

我正在尝试通过php调用更新json文件。在我的控制台中，参数不为空，但是当我检索json文件时，该值不存在。

保存功能如下：

Handsontable.Dom.addEvent(save, 'click', function() {
  var dataarray = JSON.stringify(hot.getData());
  ajax ('json/projectupdate.php', 'POST', {"infos:":dataarray}, function (res) {
    console.log (dataarray)
  });

在控制台中，结果如下：

[["test1","","gep2","",null,null,null,null,null],["","test1","","gep2",null,null,null,null,null],["dag","","test1","","gep2",null,null,null,null],["","dag","","test1",null,"gep2",null,null,null],["","","dag","","test1",null,"gep2",null,null],["","","","dag",null,"test1",null,"gep2",null],[null,null,null,null,"dag",null,"test1",null,null],[null,null,null,null,null,"dag",null,"test1",null],[null,null,null,null,null,null,"dag",null,"test1"],[null,null,null,null,null,null,null,"dag",null],[null,null,null,null,null,null,null,null,null]]

这是我在表格中写的实际内容。然后我传递（或者至少我尝试传递）我的var到我的（projectupdate.php）php文件：

<?php 
  $myFile = "project.json"; 
  $fh = fopen($myFile, 'w') or die("can't open file"); 
  $stringData = $_POST['infos']; 
  $stringData1='{ "data":'$stringData'}'; 
  fwrite($fh, $stringData1); 
  fclose($fh); 
?>

结果是projectupdate.php写在project.json "{ "data":}"上，但没有其他内容。我肯定做错了。
