PHP mail（）从不工作[关闭]

Question

I am using mail() on my site, and the function is working, but the from address is not showing my email address, it is showing [e-mail]

$ito_email = "$inameuser";
$ifrom_email = "[e-mail]";
$isubject = "My subject";
$icomment =  "Hello $inameuser,

"
. " 
"
. "Subject: $isubjectnote"
. " 
"
. "Notice: $inote"
. " 
"
. "
"
. "Many thanks";

//send email
mail($ito_email, "$isubject", $icomment, "From: Support " . $ifrom_email);

Answer 1

Changing

mail($ito_email, "$isubject", $icomment, "From: Support " . $ifrom_email);

to

mail($ito_email, "$isubject", $icomment, "From: Support <" . $ifrom_email . ">");

Should allow you to include a readable name as well as the FROM e-mail address.
