Question
MySQL, PHP does table exist
I need a way to determin if a table exists in a MySQL database prior to creating it.
This function needs to work in PHP
Ex
if (!tablename exists)
{
CREATE TABLE tablename (field 1, etc....)
}
else
{
echo "Table existss already!"
}
I need the function that determines if the tablename exists.
Thanks,
Keith

You could always catch the error when the table does exist:
i.e.:
mysql> create table item(myrow INT);
ERROR 1050: Table 'item' already exists
Use the mysql_errno() function in PHP after calling the create table and if you get error 1050 tell the user the table already existed. In this situation I would do an error catch so as to not slow your code down with checks for existing tables that may not necesscarily need to be done.
That being said, you could parse the output of SHOW TABLES to see if the tablename is amoung the tables listed.
