Custom Php Function

1. Php function to generate a unique random number between two range and creates an array with  keys and another for its values.

function uniqueNumber($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
return array_slice($numbers, 0, $quantity);
}

$pageno = array(1,2,3,4,5);
$randomPageno = uniqueNumber(1,5,5);
$mapPage = array_combine($pageno, $randomPageno);
print_r ($mapPage);

Output : Array ( [1] => 5 [2] => 1 [3] => 3 [4] => 2 [5] => 4 )

Where array() will generate new array with initial value pass as parameter,

uniqueNumber(1,5,5) – custom function to generate an array with a unique number between two range.

function rate_round($rating){
$whole = floor($rating);
$fraction = $rating - $whole;

if($fraction >= .75 && $fraction <= .99){ $ratingStar = floor($rating) +1; } elseif ($fraction >= .25 && $fraction <= .74){
$fraction = .5;
$ratingStar = floor($rating) + $fraction;
}
else{
$ratingStar = floor($rating);
}
return $ratingStar;
