<?php //Find Minimum and Maximum Values $min = 20.55;//Minimum Price $max = 10000.89;//Maximum Price $numofRanges = 5; //Split the numbers in to 5 price ranges /*For eg Price 20$ -----------200$ 200$-----------400$ 400$-----------600$ */ $value = (float)($max/$numofRanges); //Find the value to increment $range = array(); $min_temp = $min; for($i=1;$i<=$numofRanges;$i++) { $temp = $min + $value; if($temp > $max) { $temp = $max; } if($min_temp != $min) { $min_temp = round($min_temp); } if($temp != $max) { $temp = round($temp); } $range["$min_temp"] = $temp; $min_temp = $temp; $min_temp += 1; $min = $temp; } $str = ''; foreach($range as $min=>$max) { $str .= $min."\$--------------".$max."\$"; $str .= "<br/>"; } echo "<h3>Price Ranges</h3>"; echo $str; ?>
