前言：
而今咱们对“php代码换行”大约比较注意，咱们都需要剖析一些“php代码换行”的相关内容。那么小编同时在网络上网罗了一些对于“php代码换行””的相关知识，希望姐妹们能喜欢，同学们一起来学习一下吧！客户需求是把Excel的分数和年龄对应的Excel数据展示在结果页面
解决思路分析：
纵坐标分数1-72， 横坐标年龄5.5-64
数据不具有连续性，写if、else判断要72x23个，有一些可以合并，大概还是100+个if else
换个思路，横竖就是二维数组，把excel的数据解析为二维数组即可，直接粘贴复制到记事本，用\n 换行分割为一层，用空格分割为二层数组
代码如下：
$str = "54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <6255 54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <54 <6256 55 54 <54

if($age <= 5.5){ $age_key=0; }elseif($age <= 6.5){ $age_key=1; }elseif($age <= 7.5){ $age_key=2; }elseif($age <= 8.5){ $age_key=3; }elseif($age <= 9.5){ $age_key=4; }elseif($age <= 10.5){ $age_key=5; }elseif($age <= 11.5){ $age_key=6; }elseif($age <= 12.5){ $age_key=7; }elseif($age <= 13.5){ $age_key=8; }elseif($age <= 14.5){ $age_key=9; }elseif($age <= 15.5){ $age_key=10; }elseif($age <= 16.5){ $age_key=11; }elseif($age <= 17.5){ $age_key=12; }elseif($age <= 18.5){ $age_key=13; }elseif($age > 18.5 &&$age <= 24){ $age_key=14; }elseif($age >= 25 &&$age <= 29){ $age_key=15; }elseif($age >= 30 &&$age <= 34){ $age_key=16; }elseif($age >= 35 &&$age <= 39){ $age_key=17; }elseif($age >= 40 &&$age <= 44){ $age_key=18; }elseif($age >= 45 &&$age <= 49){ $age_key=19; }elseif($age >= 50 &&$age <= 54){ $age_key=20; }elseif($age >= 55 &&$age <= 59){ $age_key=21; }else{ //if($age >= 60 &&$age <= 64) $age_key=22; }最后测试和检查一下，score是有可能大于72的，key越界，所以限制一下
$score > 72 ? $score=72:"";
