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

tnx,

but this one will gove more easiest way (i hope)...
[code=php]
if(!(mysql_quer y("select * from table")))
{
echo "table not found";
}
else
{
echo "table found";
}
[/code]

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:
[code=mysql]
SHOW TABLES LIKE 'myTableName';
[/code]
Which would return an empty set if the table doesn't exists, or a single row if it does.

P.S.
