This should work for you, this recursive function loops the array,
if it gets array again, calls itself

function convert2int($var) {
   foreach($var as $k => $v ) {
       if(is_array($v)) {
       } else {
   return $var;



I have a bunch of form variables that I need to process as integers.
The problem is that some users are writing in values with commas - e.g.
100,000, and that isn't read as an integer. There's more than one
variable so I don't want to have to do a string replace for each one.
Is there a general way to curb this problem?

Thanks, Doug
