复制代码 代码如下:

 //php 不同系统的换行 
//不同系统之间换行的实现是不一样的 
//linux 与unix中用 \n 
//MAC 用 \r 
//window 为了体现与linux不同 则是 \r\n 
//所以在不同平台上 实现方法就不一样 
//php 有三种方法来解决 

//1、使用str_replace 来替换换行 
$str = str_replace(array("\r\n", "\r", "\n"), "", $str);  

//2、使用正则替换 
$str = preg_replace('//s*/', '', $str); 

//3、使用php定义好的变量 (建议使用) 
$str = str_replace(PHP_EOL, '', $str);  
?>
