Question

I have a multi-dimensional array which contains ten thousands of data. A lot… The array is structured like this:

Array (  

  [0] => Array ( [0] => city [1] => code [2] => country )  

  [1] => Array ( [0] => city [1] => code [2] => country )     

  )

What I am trying to do is to insert the array values city, code and country into a table in a mysql database. I found posts that match exactly what I want to do, but for some reason it is not working with me. When I say it is not working I mean that the php doesn’t even start. If I remove the here below code, the file runs normaly. So the problem really comes from that code portion. Hope someone will not mind helping me. Thank you in advance. Cheers. Marc.

//some code to build the array
//db_connect code

$sql = array(); 
foreach( $myarray as $row ) 
    {
    $sql[] = '("'.$row[0].'", "'.$row[1]).'","'.$row[2].'")';
    }

mysql_query('INSERT INTO test (t_city, t_code, t_country) VALUES '.implode(',', $sql));

Answer 1

As said before, the error in building the sql array, is a surplus bracket. Change

$sql[] = '("'.$row[0].'", "'.$row[1]).'","'.$row[2].'")';

to

$sql[] = '("'.$row[0].'", "'.$row[1].'","'.$row[2].'")';

As ashein noted in comments, the query length is limited by the “max_allowed_paket” variable. If the query is larger than this, an error is raised and connection gets closed.
