Question

I can not get a < to go into a an array or echo out. If I use echo "From: <[e-mail]>"; the result is From:.

If I use

$mailheader[] = "From: ".$current_user->display_name." <".$current_user->user_email.">\r\n"; 
$mailheader[] = "Reply-To: ".$current_user->display_name." <".$current_user->user_email.">\r\n"; 

$mailheader[] = "Content-type: text/html; charset=iso-8859-1\r\n"; 

var_dump($mailheader);

The result is

array(3) 
{ 
    [0]=> string(37) "From: REMOVED " 
    [1]=> string(41) "Reply-To: REMOVED " 
    [2]=> string(46) "Content-type: text/html; charset=iso-8859-1 "
}

It does not show anything starting with the < I have searched but I can’t see why this is. I have tried different ways including adding a \ before < but still it ignores everything past the <.

Answer 1

That’s because < and > have special meaning in HTML: the browser thinks that you are starting an HTML tag.

If you want to see what the real contents of the variable are, either view source or use htmlspecialchars on the output.
