php - How to add Tabs and Line Breaks from Array using file_put_contents -

i connecting sqlite database. use following query results:

$db = new sqlite3('sshtunnel.sqlite'); $results = $db->query('select * tunnel'); 

now, want add tabs , line breaks row array using file_put_contents in php:

while ($row = $results->fetcharray(sqlite3_assoc)) {     file_put_contents($file, $row, file_append).php_eol; } 

the results displayed unformatted in 1 line:

testtesttest   test   test   test 

i wish have structure:

test   test   test test   test   test 

where mistake?

while ($row = mysqli_fetch_row($results)) {    foreach($row $value)    {      $value .= '|';//use ever char append      file_put_contents($file, $value, file_append | lock_ex);    }    file_put_contents($file, '\n', file_append | lock_ex); }
