Check the refmanual for the create table syntax and read about the IF NOT EXISTS clause.

but this one will gove more easiest way (i hope)...
Expand|Select|Wrap|Line Numbers
  1. if(!(mysql_query("select * from table")))
  2. {
  3. echo "table not found";
  4. }
  5. else
  6. {
  7. echo "table found";
  8. }

That is an extremely wasteful method. You would in fact be fetching ALL the data from that table, just to see if it exists.

A far better way would be to use the SHOW TABLES command, like:
Expand|Select|Wrap|Line Numbers
  1. SHOW TABLES LIKE 'myTableName';
Which would return an empty set if the table doesn't exists, or a single row if it does.
