使用 PHP 将 JSON 转换为 CSV 格式
我正在尝试使用php脚本将json文件转换为csv格式。代码如下:
if (empty($argv[1])) die("The json file name or URL is missed\n");
$jsonFilename = $argv[1];
$json = file_get_contents($jsonFilename);
$array = json_decode($json, true);
$f = fopen('output.csv', 'w');
$firstLineKeys = false;
foreach ($array as $line)
{
if (empty($firstLineKeys))
{
$firstLineKeys = array_keys($line);
fputcsv($f, $firstLineKeys);
$firstLineKeys = array_flip($firstLineKeys);
}
fputcsv($f, array_merge($firstLineKeys, $line));
}
这种工作,但只返回JSON文件的外部变量,并且我收到“数组到字符串转换”警告
JSON 数据如下所示:
{"type":"NON_ATTRIBUTED","conversion":{,"value_1":"000000100355321","value_3":"XXXX","value_4":"12667","value_5":"6"},"stream_type":"COOKIE"}
{"type":"ATTRIBUTED","conversion":{,"value_1":"000000167865321","value_3":"YYYY","value_4":"12668","value_5":"0"},"stream_type":"COOKIE"}
{"type":"NON_ATTRIBUTED","conversion":{,"value_1":"000000134535321","value_3":"AAAA","value_4":"12669","value_5":"9"},"stream_type":"COOKIE"}
{"type":"NON_ATTRIBUTED","conversion":{,"value_1":"000000100357651","value_3":"WWWW","value_4":"12670","value_5":"2"},"stream_type":"COOKIE"}
我得到的输出是:类型,转换,stream_type NON_ATTRIBUTED,数组,COOKIE NON_ATTRIBUTED,数组,COOKIE
我期望的输出是:类型,转换,value_1,value_3,value_4,value_5,stream_type NON_ATTRIBUTED,000000100355321,XXXX,1267,6,COOKIE..
感谢帮助,因为这对我来说非常新
