Using Php to Populate a Drop Down List Box From a Mysql Database Table
5 Nov
Often develop if you create Web pages or applications, it is necessary to establish a combo box that contains entries of a table of database. You could always hard code the items in the dropdown list, but it's not very elegant, and can lead to problems if the entries in the change database table at a later date. It's much better to extract directly from entries in the database table data and then fill the dropdown list box with entries.

insert into years (yearID, year) values ('1 ', '2007-2008') INSERT INTO years (yearID, year) values ('2 ', '2008-2009') INSERT INTO years (yearID, year) values ( '3 ', '2009-2010') INSERT INTO years (yearID, year) values ('4 ', '2010-2011') INSERT INTO years (yearID, year) values ('5 ', '2011 -2012') insert into years (yearID, year) values ('6 ', "2012-2013");
The following PHP script populate list. (Php) which would constitute a form to extract all entries in the table 'years of database and use it to fill the combo box.
