Error in your SQL syntax while Inserting to table

Question

I am receiving an error

error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'all (Abonent, Opponent, Type, Data, Duration, idBase, IMEI, Direction) value' at line 1

while trying to run this code:

$sql = "SELECT * from table";
$res = mysqli_query($conn, $sql);

while ($row = mysqli_fetch_row($res)){
if ($row[2]=='Передача данных'){$type = 'Интернет';}else {$type = NULL;}
$date = date_create_from_format ( 'd.m.Y H:i:s', $row[3]);
$da=  date_format($date, 'Y-m-d H:i:s');

$mysql = "INSERT INTO all (Abonent, Opponent, Type, Data, Duration, idBase,         IMEI, Direction) 
  values ('$row[0]', '$row[1]','$type', '$da', '$row[4]', '$row[5]',     '$row[6]', '$row[7]')";
$result = mysqli_query($conn, $mysql);
  }

I've checked similar questions here: none of the attribute names are seem to be keywords, neither is in the use of backticks. Types of my table attributes:

Abonent bigint(12)  (key)
Opponent    bigint(12)  
Type    text    
Data    datetime    
Duration    bigint(20)  
idBase  bigint(10)  (key)   
IMEI    bigint(16)      
Direction   varchar(15)

Answer 1

All is a keyword. Do not use it as table name or escape it using backticks.
