Array help please

[atokatim]

I am attempting to get a form to send back a group of numbers and have these numbers put into an array. After they are put into an array I need to have a script that will automatically find the number that is repeated the most and display it.

example : array(1, 2, 2, 3, 3, 1, 2);
Result : 2

any suggestions?

Something like this maybe...

$arrArray = array(1, 2, 2, 3, 3, 1, 2, 3, 3, 2, 2, 2, 2);
$arrSums = array();
$intMax = 0;
foreach($arrArray as $intValue) {
    if(!isset($arrSums[$intValue])) {
        $arrSums[$intValue] = 0;
    }
    $arrSums[$intValue]++;
    if($intMax < $arrSums[$intValue]) {
        $intMax = $intValue;
    }
}
printf('The most repeated value is : %s<br />', $intMax);

Not optimized, untested...

hmmm....it worked on the first test, but after i tested it again on some different numbers, it picked the lowest number

this is what i got :

Array ( [93] => 1 [91] => 2 [92] => 1 )
The most repeated value is : 93

the answer should be 91

My mistake was with the setting of $intMax...

 $arrArray = array(93, 91, 91, 92);
$arrSums = array();
$intMax = 0;
$intMaxWho = 0;
foreach($arrArray as $intValue) {
    if(!isset($arrSums[$intValue])) {
        $arrSums[$intValue] = 0;
    }
    $arrSums[$intValue]++;
    if($arrSums[$intValue] > $intMax) {
        $intMax = $arrSums[$intValue];
        $intMaxWho = $intValue;
    }
}
printf('The most repeated value is %s with %s repetitions<br />', $intMaxWho, $intMax);

i think i got it....testing it out now.

// Array ( [93] => 1 [91] => 2 [92] => 1 ) 

$array2 = array_count_values($array);
echo "<br>";
$count = 0;
$result = 0;
foreach($array as $ar){
	if($count < $array2[$ar]){
		$count=$array2[$ar];
		$result=$ar;
	}
}
echo $result;  // = 91
