如何使用file_put_contents从数组中添加制表符和换行符 - How to add Tabs and Line Breaks from Array using file_put_contents

How to add Tabs and Line Breaks from Array using file_put_contents

我正在连接到SQLite数据库。我使用以下查询来获取结果:

$db = new SQLite3('sshTunnel.sqlite');
$results = $db->query('SELECT * FROM TUNNEL');

现在，我想在PHP中使用file_put_contents从行数组中添加制表符和换行符:

while ($row = $results->fetchArray(SQLITE3_ASSOC))
{
    file_put_contents($file, $row, FILE_APPEND).PHP_EOL;
}

结果以不格式化的方式显示在一行中:

TestTestTest   Test   Test   Test

我希望有这样的结构:

Test   Test   Test
Test   Test   Test

错误在哪里?

while ($row = mysqli_fetch_row($results))
{
   foreach($row as $value)
   {
     $value .= '|';//use what ever char you what to append
     file_put_contents($file, $value, FILE_APPEND | LOCK_EX);
   }
   file_put_contents($file, ''n', FILE_APPEND | LOCK_EX);
}

我解决了这个问题。trim()成功了

while ($row = $results->fetchArray(SQLITE3_ASSOC))
{
    foreach ($row as $value)
    {
        file_put_contents($file, trim($value) . ", ", FILE_APPEND | LOCK_EX);
    }
    file_put_contents($file, "'n", FILE_APPEND | LOCK_EX);
}
