Max, Min function

[Anon]

What is wrong ?
echo "MAX: ".max($data1)." : ";
echo "MIN: ".min($data1)." : ";
$max_in = "max($data1)";
$min_in = "min($data1)";
echo "$max_in";
echo "$min_in";
The first two echo good, the second two not.
Result: MAX: 6623.58 : MIN: 5670.98 : max(Array) min(Array)

Umm.. yes? What did you expect to get
when you put an array in a string?

Or did you perhaps not see that you typed
those quotes, and you intended to type
something like $max_in = max($data1);
instead?

Thank you very much. I am a beginner.
