[PHP] Converting variables to integer

[drparker]

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

function str2int($str)
{
$str = str_replace(',', $str);  //
http://www.php.net/manual/en/function.str-replace.php

settype($str, integer);  //
http://www.php.net/manual/en/function.settype.php

if (is_int($str))  // http://www.php.net/manual/en/function.is-int.php
return $str;
else
return false;
}

Loop through your form variables and call this function.  Good luck,
-Kevin

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)) {
   $var[$k]=convert2int($v);
   } else {
   $var[$k]=str_replace(',',$v);
   }
   }
   return $var;
}

$_POST=convert2int($_POST);

Ooops my str_replace() function needs one more parameter.
str_replace(',', '', $str);
