如何格式化json文件？

我是JSON的新手，我想知道如何格式化我的JSON文件，以便能够在条形图中呈现它。如何格式化json文件？

我有下面的PHP代码：

<?php 

$search_value=$_POST["search"]; 
$mysqli = new mysqli('localhost','root','password','mydb'); 
$myArray = array(); 
if ($result = $mysqli->query("SELECT * FROM transcriptome WHERE genename LIKE '%$search_value%'")) { 

    while($row = $result->fetch_array(MYSQL_ASSOC)) { 
      $myArray = $row; 
    } 
    file_put_contents('jsonoutput.json', json_encode($myArray)); 
    echo json_encode($myArray); 
} 

$result->close(); 
$mysqli->close(); 
?>

我的实际输出：（给定的基因（xkr4）作为输入）

{"genename":"xkr4","TA11MEAN":"974.25","TA11STD":"99.0085223605","TA21MEAN":"710.75","TA21STD":"115.79831605","TA22MEAN":"736.5","TA22STD":"115.79831605","TA23MEAN":"903.75","TA23STD":"107.283211641","TB11MEAN":"799.25","TB11STD":"97.2660655111","TB21MEAN":"658","TB21STD":"91.7959694104","TB22MEAN":"592.75","TB22STD":"70.9379129944","TB23MEAN":"864","TB23STD":"92.7280971443"}

我如何想获得我的输出：

{"genename":"xkr4",{"TA11MEAN":"974.25"},{"TA11STD":"99.0085223605"},{"TA21MEAN":"710.75"},{"TA21STD":"115.79831605"},{"TA22MEAN":"736.5"},{"TA22STD":"115.79831605"},{"TA23MEAN":"903.75"},{"TA23STD":"107.283211641"},{"TB11MEAN":"799.25"},{"TB11STD":"97.2660655111"},{"TB21MEAN":"658"},{"TB21STD":"91.7959694104"},{"TB22MEAN":"592.75"},{"TB22STD":"70.9379129944"},{"TB23MEAN":"864"},{"TB23STD":"92.7280971443"}}

如果有人可以给我这个方向（或解决它）那太棒了！

在此先感谢:)

'json_encode（$的数据，JSON_PRETTY_PRINT）' – Sammitch

你确定你需要这个漂亮的印刷？ JS，或者任何你用来解码json的东西都不会在意，只要它是有效的JSON即可。 – JimL

这是没有道理的，为什么要关心JSON风格或美丽，它必须是有效的。 –

我建议你首先检查你如何获取数组中的数据。 $ myArray []应该填充如下所示的数据。然后使用JSON_PRETTY_PRINT。

/*USED TO SHOW FULL ARRAY SIZE*/ 
    ini_set('xdebug.var_display_max_depth', -1); 
    ini_set('xdebug.var_display_max_children', -1); 
    ini_set('xdebug.var_display_max_data', -1); 


    $myArray=array("genename"=>array(array("xkr4"=>array(
    array("TA11MEAN"=>"974.25","TA11STD"=>"99.0085223605"), 
    array("TA21MEAN"=>"710.75","TA21STD"=>"115.79831605"), 
    array("TA22MEAN"=>"736.5","TA22STD"=>"115.79831605"), 
    array("TA23MEAN"=>"903.75","TA23STD"=>"107.283211641"), 
    array("TB11MEAN"=>"799.25","TB11STD"=>"97.2660655111"), 
    array("TB21MEAN"=>"658","TB21STD"=>"91.7959694104"), 
    array("TB22MEAN"=>"592.75","TB22STD"=>"70.9379129944"), 
    array("TB23MEAN"=>"864","TB23STD"=>"92.7280971443"), 

)))); 
$jsonData=json_encode($myArray,JSON_PRETTY_PRINT); 

var_dump($jsonData);

This is how your data looks like from database it is a array of rows row is a object

我解决了它：

<?php 

$search_value=$_POST["search"]; 
$mysqli = new mysqli('localhost','root','password','mydb'); 
$myArray = array(); 
if ($result = $mysqli->query("SELECT * FROM transcriptome WHERE genename LIKE '%$search_value%'")) { 


    while($row = $result->fetch_array(MYSQL_ASSOC)) { 
    $myArray = $row; 
    } 
    //file_put_contents('jsonoutput.json', json_encode($myArray)); 
    $json = json_encode($myArray); 
    $array = json_decode($json, true); 

    $new_array = array(); 
    foreach($array as $key => $value){ 
    $newarray[] = array($key=>$value); 
    } 

echo json_encode($newarray); 
file_put_contents('jsonoutput.json', json_encode($newarray)); 



} 


$result->close(); 
$mysqli->close(); 
?>
