/*
This function should be changed...

 When i check if a value is in array I would expect it to behave like the equal $var1 == $var2, or $var1 === $var2 to check the types if they are equal in the strict mode.. 

The in_array function should be changed if you ask me... 
*/

$status = "on";

function is_valid(&$status) {
   $valids = array(0, 1);

   if (in_array($status, $valids)) {
       return true;
   }
   else if ( $status == "on") {
       $status = 1;
       return true;
   }
   return false;
}

var_dump(is_valid($status));// => true;
var_dump($status); // => it is a striung "on"; Meaning it was validated from the first part of the function where somehow it is found in the array with valid stings(int) ... 

/*

this returns true...

I guess i didn't expect it.. Maybe this is the way it should be?

When you use strings in the array ( => $valids = array("0", "1"); it returns the expected results. 

One of the notes on your page: 
Note: If needle  is a string, the comparison is done in a case-sensitive manner. I don't understand how this can be used for any purpose but to foll developers in getting wrong results from in_array check..

Reproduce code:
---------------
$status = "on";

function is_valid(&$status) {
   $valids = array(0, 1);

   if (in_array($status, $valids)) {
       return true;
   }
   else if ( $status == "on") {
       $status = 1;
       return true;
   }
   return false;
}

var_dump(is_valid($status));// => true;
var_dump($status); // => it is a striung "on"; Meaning it was validated from the first part of the function where somehow it is found in the array with valid stings(int) ...

Just thought to report it.

Expected result:
----------------
The expected result is to get the string validated by the second part... and get it converted to 1 based to the reference call.. 


I read the documentation... 

And i see nowhere that if you use 0 or one in the array it returns true...

This is illogical.. 

And very very confusing... and reasonless.
