Email header question

Jazzy_Girl

Hi, can you use the same header variable $header to call on several facets of a header? For example below are several header strings. Will one $header variable in the mail( function use them all? I tried it but couldn't tell. Some of the fields are hidden. Thanks a lot.

$eol="\r\n";
$header .= 'From: MyName<'.$fromaddress.'>'.$eol;
$header .= 'Reply-To: MyName<'.$fromaddress.'>'.$eol;
$header .= "X-Mailer: PHP v".phpversion().$eol;

mail($emailaddress, $emailsubject, $msg, $header);

Yes you can however in your example you should get into the habit of having a variable initiated before trying to concatenate, as PHP is loosely typed you can get away with it but going into C for example you couldn't.

$eol="\r\n";
$header = 'From: MyName<'.$fromaddress.'>'.$eol;
$header .= 'Reply-To: MyName<'.$fromaddress.'>'.$eol;
$header .= "X-Mailer: PHP v".phpversion().$eol;
mail($emailaddress, $emailsubject, $msg, $header);

Thanks much, thats very good news, not sure what you mean though. Should one of those be placed before the other?

Well you are using .= this is string concatenation. To properly concatenate a string the variable must be initiated e.g.

$header = "";

or in the above

$header = 'From: MyName<'.$fromaddress.'>'.$eol;

A bit on string concatenation from the manual http://www.php.net/manual/en/language.operators.string.php

And if you have your php switched to E_ALL, you'll notice taht even php doesn't like it at all..
