Hello all,

I'm stuck in a serious problem, I need a code of Email validator in php. It will check whether there is a real email address or not, i.e it should not be "abcd@xyz.com" that means it will check the domain(yahoo.com, gmail.com, aol.com etc..) as well as the user id.....

PLZzzzzzzzzzzzzz help me it's realy very urgent.............

plzzzzzzzzzzz reply..................

this is the code:

var m = document.form1.emailid.value
	var cnt=0,spc=0,dot=0;
	for(var i=1;i<=m.length;i++)
	{
		if(m.charAt(i)=="@") cnt++;
		if(m.charAt(i)==" ") spc++;
		if(m.charAt(i)==".") dot++;
	}
	lnm=m.length
	if(cnt==0||cnt>1||spc!=0||dot==0 ||lnm<=2 )	{alert("Please Enter Valid E-mail Id ");document.form1.emailid.focus();return false;	}

I've done this way but its not working....
