integer field

[ketvin]

Dear lists,

Simple question for geniuses outthere: 

my database has an integer field where i created with CREATE table test (first 
int(10));

so when i use php to grab the "first" field and read it in $myrow["first"] , then try 
to make the number increase by doing a 

$increase = $myrow["first"] + 1;

but the $increase is still holding the same number. 



is anything wrong with my mysql db configuration or php scripts? 


thanks
