I'm not sure if this is the right place to post these kind of questions, if it's not so, please (politely) let me know... :-)
I need to save files greater than 16MB on a mysql database from a php site...
I've already changed the c:\xampp\mysql\bin\my.cnf
and set max_allowed_packet to 16 MB, and everything worked fine
then I set it to 32 MB but there´s no way I can handle a file bigger than 16 MB
I get the following error:
'MySQL server has gone away'
(the same error I had when max_allowed_packet was set to 1MB)
there must be some other setting that doesn´t allow me to handle files bigger than 16MB
maybe the php client, I guess, but I don't know where to edit it
this is the code I'm running
when file.txt is smaller than 16.776.192 bytes long, it works fine, but
if file.txt has 16.777.216 bytes i get the aforementioned error
oh, and the field download.content is a longblob...
$file = 'file.txt';
$file_handle = fopen( $file, 'r' );
$content = fread( $file_handle, filesize( $file ) );
fclose( $file_handle );
db_execute( 'truncate table download', true );
$sql =
"insert into download(
code, title, name, description, original_name,
mime_type, size, content,
user_insert_id, date_insert, user_update_id, date_update )
values (
'new file', 'new file', 'sas.jpg', 'new file', '$file',
'mime', " . filesize( $file ) . ", '" . addslashes( $content ) . "',
0, " . db_char_to_sql( now_char(), 'datetime' ) . ", 0, " . db_char_to_sql( now_char(), 'datetime' ) . " )";
db_execute( $sql, true );
(the db_execute funcion just opens the connections and executes the sql stuff)
