使用PHP从JSON文件中提取键值对输出

时间：2019-02-05 10:30:11

标签： php json

我想使用PHP从JSON格式的文件中提取键值对输出，并将其放入具有精确键列的html表和数据库中。我尝试了Extract JSON ouput to get line by line key pair values using PHP中提到的代码，但是它不适用于多行，并且由于第二个键中有多行，所以第二行本身输出错误。

正如我们在那讨论过的那样，请提交单独的问题以避免混乱同一问题。

尝试输入的代码：

    $resultFile = fopen($resultURL, "r");
    #$lines = file($resultURL, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
    #print_r ($lines);
    #exit;

    while (!feof($resultFile)) {
        $line = trim(fgets ($resultFile));
        $line = str_replace("\\\"", "", $line);
        $line = stripslashes($line);
        $lineArray = json_decode($line, true);

        parseData($lineArray);
        echo "</tr>";

    fclose ($resultFile);

function parseData($array) {

   foreach ($array as $key => $value) {
     if (is_bool($value)) {

您的JSON似乎格式不正确。您错过了逗号和方括号。

这是一个非常基本的解决方案，但是您可以按照以下方法更正JSON：

添加逗号

$json = str_replace("} {", "}, {", $original_json);

清理一些代码（这很粗糙。适合您的情况，但根本不是最好的！）

$json = str_replace("\[", "[", $json);
$json = str_replace("\]", "]", $json);

将其包装在[]

内 
$your_json_string = "[" . $json . "]";

然后您就可以使用

$json_parsed = json_decode($your_json_string);

和

echo "<table class='table create-release-note-table'>
<thead>
<tr>
<th>#</th>
<th>Ticket ID</th>
<th>Status</th>
<th>Components</th>
<th>Affected Versions</th>
<th>Fix Versions</th>
<th>Description</th>
</tr>
</thead>
<tbody>";

foreach($json_parsed as $json_object){
   echo "<tr>";
   echo "<td></td>";
   echo "<td>" . $json_object->key . "</td>";
   echo "<td>" . $json_object->status. "</td>";
   echo "<td>" . $json_object->components. "</td>";
   echo "<td>" . $json_object->affectedVersions. "</td>";
   echo "<td>" . $json_object->fixVersions . "</td>";
   echo "<td>" . $json_object->customerFacingInfo . "</td>";
   echo "</tr>";
}
echo "</tbody>
</table>";

就这样

恐怕问题出在json文件方面。

如果我理解正确，那么您的问题中公开的JSON文件内容应该是单个json文件。

如果是这样，则json的格式似乎不正确。

您的json的结构如下（我删除了内容的某些部分以帮助阐明我的观点）：

{"key":"SEM-5765"} 
{"key":"SEM-3325"} 
{"key":"SEM-2755"}

不是单个json，而是单个文件中的3个不同的json。

正确的json结构应该是：

[
{"key":"SEM-5765"}, 
{"key":"SEM-3325"}, 
{"key":"SEM-2755"},
]

哪个是json数组和正确的json结构。

所以我认为您有两种可能：

  1. 您可以更正json结构
  2. 您可以通过将每一行分开并将每行特征化为一个json来读取文件

无论哪种方式，您都必须在代码中添加一个步骤，以遍历每个line / json实体

答案 2 :(得分：1)

根据您的情况，您可以使用explode和implode php函数来获取所需的输出。 我添加了几行代码：

$lineExplode = explode('}',$line);
$line = implode(',',$lineExplode);
$lineArray = json_decode("[".$line."]", true);

所有其他代码与您的示例相同：

<?php

echo "<table class='table create-release-note-table'>
                <thead>
                    <tr><th>#</th><th>Ticket ID</th><th>Status</th><th>Components</th><th>Affected Versions</th><th>Fix Versions</th><th>Description</th></tr>
                </thead>
            <tbody>";
    $i = 0;

    $resultFile = fopen($resultURL, "r");
    #$lines = file($resultURL, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
    #print_r ($lines);
    #exit;

    while (!feof($resultFile)) {
        $line = trim(fgets ($resultFile));
        $line = str_replace("\\\"", "", $line);
        $line = stripslashes($line);
        $lineExplode = explode('}',$line);
        $line = implode(',',$lineExplode);
        $lineArray = json_decode("[".$line."]", true);
        echo "<tr><td>" . ++$i . "</td>";
        parseData($lineArray);
        echo "</tr>";
    }
    echo "</tbody></table>";
    fclose ($resultFile);


// Parse release note data

function parseData($array) {
   $value = str_replace(",", ";", $value);
   foreach ($array as $key => $value) {
     if (is_bool($value)) {
        echo ("<td>" . $value? 'true' : '') . "</td>";
     } else {
        echo "<td>" . $value . "</td>";
     }
  }
}

?>
