PHP如何將JSON轉(zhuǎn)換為XML？

首先使用“file_get_content()”函數(shù)將JSON數(shù)據(jù)讀取出來；

$json = file_get_contents('./data.js');

然后使用函數(shù)“json_decode()”將數(shù)據(jù)進(jìn)行解碼；

$data = json_decode($json, true);

接著循環(huán)數(shù)據(jù)拼接成XML字符串；最后寫入文件中即可。

$string=""; 
foreach($data as $k=>$v){ 
    $string .="<".$k.">"; 
    //取得標(biāo)簽數(shù)據(jù) 
        $string .=$v; 
    $string .="";  
}

封裝示例

addtypes = false; // type="string|int|float|array|null|bool"
    public function export($data)
    {
        $data = array($this->root => $data);
        echo '';
        $this->recurse($data, 0);
        echo PHP_EOL;
    }
    private function recurse($data, $level)
    {
        $indent = str_repeat($this->indentation, $level);
        foreach ($data as $key => $value) {
            echo PHP_EOL . $indent . '<' . $key;
            if ($value === null) {
                echo ' />';
            } else {
                echo '>';
                if (is_array($value)) {
                    if ($value) {
                        $temporary = $this->getArrayName($key);
                        foreach ($value as $entry) {
                            $this->recurse(array($temporary => $entry), $level + 1);
                        }
                        echo PHP_EOL . $indent;
                    }
                } else if (is_object($value)) {
                    if ($value) {
                        $this->recurse($value, $level + 1);
                        echo PHP_EOL . $indent;
                    }
                } else {
                    if (is_bool($value)) {
                        $value = $value ? 'true' : 'false';
                    }
                    echo $this->escape($value);
                }
                echo '';
            }
        }
    }
    private function escape($value)
    {
        // TODO:
        return $value;
    }
    private function getArrayName($parentName)
    {
        // TODO: special namding for tag names within arrays
        return $parentName;
    }}$exporter = new Exporter();$exporter->export($data);
