将JSON数据写入文本文件，数据通过.post-jQuery发送到PHP文件 - Writing JSON data to a text file, data sent via .post jQuery to PHP file

Writing JSON data to a text file, data sent via .post jQuery to PHP file

我想使用jQuery和PHP将JSON数据写入文本文件。我使用将数据从JavaScript发送到PHP文件

function WriteToFile(puzzle)
    {
    $.post("saveFile.php",{ 'puzzle': puzzle },
        function(data){
            alert(data);
        }, "text"
    );
    return false;
    }

PHP文件是

<?php
$thefile = "new.json"; /* Our filename as defined earlier */
$towrite = $_POST["puzzle"]; /* What we'll write to the file */
echo $towrite;
$openedfile = fopen($thefile, "w");
$encoded = json_encode($towrite);
fwrite($openedfile, $encoded);
fclose($openedfile);
return "<br> <br>".$towrite;
?>

这是有效的，但文件new.json中的输出看起来像这样：

"{'''"answerswers'''":['''"across'''",'''"down'''"],'''"clues'''":[],'''"size'''":[10,10]}"

我不想要那些斜杠：我是怎么得到的？

尝试使用http://php.net/manual/en/function.stripslashes.php，我想假设您已经收到一个json编码的数据表单jquery

    $thefile = "new.json"; /* Our filename as defined earlier */
    $towrite = $_POST["puzzle"]; /* What we'll write to the file */
    $openedfile = fopen($thefile, "w");
    fwrite($openedfile, stripslashes($towrite));
    fclose($openedfile);
    return "<br> <br>".$towrite;

样品

    $data = "{'''"answerswers'''":['''"across'''",'''"down'''"],'''"clues'''":[],'''"size'''":[10,10]}" ;
    var_dump(stripslashes($data));

输出

    string '{"answerswers":["across","down"],"clues":[],"size":[10,10]}' (length=55)

您不需要使用json_encode，因为您从JSON中获取数据，而不需要将其放入JSON:

$thefile = "new.json"; /* Our filename as defined earlier */
$towrite = $_POST["puzzle"]; /* What we'll write to the file */
$openedfile = fopen($thefile, "w");
fwrite($openedfile, $towrite);
fclose($openedfile);
return "<br> <br>".$towrite;
