在我们用textarea时会发现回车与空格是不可看到的,所以我们利用str_replace函数将php中的\n替换成br就可以了哦。有需要的朋友可以参考。  

 代码如下 复制代码

function htmtocode($content) {
    $content = str_replace("n", "
", str_replace(" ", " ", $content));
    return $content;
}


先替换掉空格,再替换回车。
相当于:

 代码如下 复制代码
function htmtocode($content) {
    $content = str_replace(" ", " ", $content);
    $content = str_replace("n", "
",$content);  
    return $content;
}
