Question

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;

?>

这可行，但文件new.json中的输出如下所示：

"{\\\"answers\\\":[\\\"across\\\",\\\"down\\\"],\\\"clues\\\":[],\\\"size\\\":[10,10]}"

我不想要那些斜线：我是怎么得到它们的？

Answer 1

尝试使用http://php.net/manual/en/function.stripslashes.php，我想假设您已经收到了json编码的json编码数据

    $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;

示例

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

输出

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

您在从JSON获取数据时不需要使用json_encode，而不是将其放入JSON中：

$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;

将JSON数据写入文本文件，通过.post jQuery发送的数据到PHP文件
