Dynamic Variables

[Dronealone]

Hello,

I am trying to dynamically build a variable name and then access the value that is in the variable, which has been posted by a form. My code is:

$var = "HTTP_POST_VARS[industry" . "_" . $db_row[name] . "]";

$val = $$var;

echo $val;

This doesn't give me any value. If I echo the variable name, which is being constructed correctly, I get the value. Does anybody know what I'm doing wrong?

Thanks!

Why not just say:

$var = $HTTP_POST_VARS["industry_" . $db_row[name]]; Want the best answers? Ask the best questions:
