Newbie email from web page

Copy linkTweet thisAlerts:

Hello!

I’m new to php and have a question about sending mail from a webbpage.

I know that I can use syntax like:

<?php
.
.
.
$headers=”From: $emailfrom”;
mail($to, $subject, $message, $headers);
?>

to send mail but this syntax doesnt take care about “fake emailadresses” so you can write what you want as $emailfrom

I have tried to do like
<?php
if(mail($to, $subject, $message, $headers)?…
?>

but this doesnt either work….

Is there a way to control that $emailfrom is a working emailadress?

@LiLcRaZyFuZzYJan 26.2006 — you'd have to check the $emailfrom variable and test it against a RegEx ([B]Reg[/B]ular [B]Ex[/B]pression)

something like that:
[CODE]/^[-^!#$%&'*+/=?{|}~.w]+@[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*(.[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*)+$/[/CODE]</CODE>

in PHP:
<CODE lang="php">[code=php]<i>
</i> $pattern = "/^[-^!#$%&amp;'*+/=?{|}~.w]+@[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*(.[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*)+$/";
if(preg_match($pattern, $emailfrom)){
# e-mail address should be valid
}else{
# e-mail address will most probably not be valid
}
[/code]

i've read somewhere that this pattern would cover all e-mail addresses according to some specifications, but i'm not sure of that..

Your example covers the "syntax" but is there a way to control if given emailadress is existing? When you write an invalid http url you get an error message that says that current url doesnt exist. Is there a way to control if an email is existing?
