JonnoTheDev Posted August 21, 2008 Share Posted August 21, 2008 Mail headers are part of the message construct so that a mail agent can display where the message has come from, what type of content it is, the reply address, etc (you must have seen an email in Microsoft Outlooks inbox). Without the headers you may get errors when using the mail() function.

uniflare Posted August 21, 2008 Share Posted August 21, 2008 Also certain headers are required when sending to servers like hotmail, otherwise your email could end up in Junk or Spam even if it is completely clean.

Prismatic Posted August 21, 2008 Share Posted August 21, 2008 You can append a variable using .= For example, $var = "hello "; $var = "world"; echo $var; Will output "world" However, using .= $var = "hello "; $var .= "world"; echo $var; Will output "hello world" Link to comment https://forums.phpfreaks.com/topic/120729-what-is-the-use-of-headers-here/#findComment-622160 Share on other sites More sharing options...
stbalaji2u Posted August 22, 2008 Author Share Posted August 22, 2008 Wow thanks guys for your excellent replies. . well i think now i clearly understand the use of headers now but just storing the values in header variable makes what difference at all ?? because the header is not used in anywhere of the code.is there any other code that needs to append with this code?
