$lesujet = "testing ...";
$letexts = "a bunch of text   

there is a return break here

another return break as you see";

mail("myemail@gmail.com",$lesujet,$letexts,$headers);

我希望能够删除返回中断并仅保留 1，我尝试过：

 $letexts = str_replace("\r","",$letexts);
 $letexts = str_replace("\n","",$letexts);

它不起作用。我期望它输出格式如您在上面看到的文本，而不是它返回的内容（每个返回中断加倍，这很烦人）：

    a bunch of text   


    there is a return break here


    another return break as you see

像这样使用修剪功能 修剪 ：

$letexts = trim($letexts);

尝试这个：

$letexts = preg_replace("/\r\n\s*\r\n/", "\r\n", $letexts);
