[PHP] Verify E-Mail Address

[Jeff Grossman]

Hello,

I have a page which is a form for people to fill in.  There is one input 
line where the user enters in an e-mail address.  Currently the page is 
using java to verify that e-mail address.  It looks like the java code 
is only checking for an "@" side, but I want it to also check for a "." 
and the end of the domain type.  Somebody else wrote this code for me, 
and I don't know anything about java.  Could somebody show me what I 
need to do to change this java code to PHP?  If that is even possible?  
And, to do the additional verify that I would like to do on the e-mail 
address.

Here is the code:

function validate(){

form = document.subscribe;

if ( form.email.value == ""){
   alert("Please enter your email address in the \"Email Address\" and 
\"Verify Email Address\" boxes");
   form.email.focus();
   return false;
   }
   else {
   if ( form.email.value != form.vemail.value ){
     alert("Please verify you have entered the correct email address in 
the \"Email Address\" and \"Verify Email Address\" boxes");
      form.email.focus();
      return false;
      }
   }


if( form.email.length != 0)
  {
   txt = form.email.value;
   if (txt.indexOf("@")<3)
   {
   alert("This email address seems wrong. Please check the prefix and 
\"@\" sign.");
   form.email.focus();
   return false;
   }
}

if( form.vemail.length != 0)
  {
   txt = form.vemail.value;
   if (txt.indexOf("@")<3)
   {
   alert("This email address seems wrong. Please check the prefix and 
\"@\" sign.");
   form.vemail.focus();
   return false;
   }
}

}

Thanks,
Jeff
