Try:
for($i=0;$i<$count;$i++)
{
// in the global array, print the variable with the name: "item$i"
print $GLOBALS["item$i"];
}
or even:
for($i=0;$i<$count;$i++)
{
// in the post vars array, print the variable with the name: "item$i"
// this one is probably more secure.
print $HTTP_POST_VARS["item$i"];
}
Also, as an aside, unlike concatenation in vbscript (blech) you don't have
to break out of quotes all the time. That's because like in perl, php
variables within double quotes are interpolated.
So instead of writing:
print("<input type=text name=item" . $i . ">");
you may write:
print ("<input type=text name=item$i>");
Further, you don't need parenthesis with the print statement so you can
write:
print "<input type=text name=item$i>";
It's just a matter of preference, but I think it looks cleaner.
When concatenating several variables together into a string this can save a
ton of keystrokes and is easier to read and maintain.

Matt.
