解析PHP处理换行符的问题 /r/n

复制代码 代码如下:

int main ()
{
cout << "hahaha" << "/r" << "xixi" ;
}

复制代码 代码如下:

int main()
{
cout << "hahaha" << "/n" << "xixi" ;
}

复制代码 代码如下:

//Order of replacement
$str="Line1/nLine2/rLine3/r/nLine4/n";
$order=array("/r/n","/n","/r");
$replace='<br/>';
$newstr=str_replace($order,$replace,$str);
