PHP 按换行符拆分字符串不生效
<?php
$str = trim(fgets(STDIN));
$arr = explode("\n",$str);
foreach($arr as $k=>$v){
$workArr = explode(" ",$v);
$result = $workArr[0] + $workArr[1];
echo $result."\n";
$str = trim(fgets(STDIN));
$arr = explode("\n",$str);
foreach($arr as $k=>$v){
$workArr = explode(" ",$v);
$result = $workArr[0] + $workArr[1];
echo $result."\n";
}
以上为代码
拆分的时候 用 "\r","\n","\r\n",都不行
比如 输入
1 2
2 3
拆分后打印,只出现 1 2 后边的没有了
