How to pass a NULL Value in PHP/MySQL

[MayPh]

Can someone please help me on how can I pass a NULL Value in PHP/MySQL, cause everytime I pass a blank data field, it saved as 1 character space on the MySQL table.

If you want to store NULL in MySQL, make sure the field in the MySQL DB can take a NULL value, and if it can, use,

myfield = NULL

Notice no quote marks.

Hope this helps.
