Question

In PHP, I need something like this:

1) if('out of space' == mysql_error($link))
2) if(10 == mysql_error($link))
3) if(true == mysql_error('out of space'))
4) if(... whatever ....)
5) if(1024 == mysql_errno($link))
{
   echo 'DB is out of space';
}

Answer 1

You’re probably looking for errno code 1021 (ER_DISK_FULL) and/or 1041 (ER_OUT_OF_RESOURCES)

switch( mysql_errno($link) ) {
case 1021:
  // handle ER_DISK_FULL
  break;
case 1041:
  // handle ER_OUT_OF_RESOURCES
  break
