php在范围中取值并使和为100

<?php $n = array(
		&#39;0&#39; => '1.1-4.6',
		'1' => '1.2-33.7',
		'2' => '1.3',
		'3' => '1.4-30',
		'4' => '15-44',
		'5' => '1.1-4.6',
		'6' => '1.2-33.7',
		'7' => '1.3',
		'8' => '1.4-43.9',
		'9' => '9.5-44',
	);
	$nn = check_zifu($n);
	for ($ii=0; $ii  1) {		//判断是否是范围，若不是，左边界值和右边界值相同
			$nnn[$ii]['min'] = ceil($nn[$ii][0]); 
			$nnn[$ii]['max'] = floor($nn[$ii][1]);
		}else{
			$nnn[$ii]['min'] = $nn[$ii][0];
			$nnn[$ii]['max'] = $nn[$ii][0];
		}
	}
	$nnnn = getNum($nnn);
	echo "<pre class="brush:php;toolbar:false">";
	print_r($nnnn);

function check_zifu($a){
	$c = array();
	for ($i=0; $i  100){	//若左边界值和大于100或右边界值和小于100，不成立
		for ($iii=0; $iii  100) {
					$c['min'][$iii] = $c['min'][$iii] - (array_sum($c['min']) - 100);
					return $c['min'];
					break;
				}
			}
		}
	}else if($min_sum == 100){		//若左边界值和为100
		for ($ii=0; $ii
