hello all,
let's say i have this:
$a="varone=hello world|vartwo=2.44|varthree=100|";
now i do this:
$b=explode('|',$a);
$z=count($b);
for ($x=0;$x<$z;$x++) {
$tmp=explode('=',$b[$x]);
....
and i want to find out if $tmp[1] is a string or an integer (that's really
all I need to determine so i can put
together an SQL statement that puts single quotes around strings and none
around integers). Obviously
i won't know at design time all of the variables and their values. Thank
you.
