variable problem

[Anon]

hi!
i have a big prob. to explain it to you i did this tiny prog.

i want to make a loop

for ($i=0; $i<5; $i++) {
echo $field ?????? ;
}

and i got variables:

$field0
$field1
$field2
$field3
$field4

the prob. is where the ???? marks are.
how i have to combine the "$field"
and the "$i" to get the results of
variables??

thanx a lot krys

do:

echo ${"field".$i};

alternatively, you could use "real" arrays. for this, have a look at the arrays section in the manual.

You need to add a couple of quotes viz:

echo "$field ?????";

or

echo $field."?????";

See matto's reply for the other problem.
