Hi i'm new to php and mysql.
I'm wondering how can i use PHP to check if a table in my mysql database contains a ROW which have the specific ID and if not add the data to the table .
For example,
Table structure:(Table name : record) ID , DATA
i have ID=123 and DATA=hello stored in a variable in the php code , how can i use php sql query to find out whether the data exist by checking using its ID in the table , if not , INSERT the ID and DATA into the table.
I hope you understand.
p/s i have connected the php script to the database
