PHP: Testing whether three variables are equal

Question

I\'ve never come across this before, but how would you test whether three variables are the same? The following, obviously doesn\'t work but I can\'t think of an elegant (and co

Answer 1

I had a unique situation in which I needed to see if the amount of items in three arrays was the same much like this scenario.

This is what I came up with:

(Assume that fields, operators and values are all arrays)

$allfieldscount = array(count($fields), count($operators), count($values)); //store an array of the count of all the arrays.

$same = array_count_values($allfieldscount);//returns an array by values in the array.  We are looking to see only 1 item in the array with a value of 3.

if(count($same) != 1){
    //Then it's not the same
}else{
   //Then it's the same
}

This tactic counts the fields in the different arrays and by using array_count_values if they are all the same then the count of the array it returns will be '1', if it's anything else then it's not the same. Look up array_count_values on php.net to understand more what its doing.
