Not PHP, but in js, I use this:
function emailCheck(str) {
var at="@"
var dot="."
var lat=str.indexOf(at)
var lstr=str.length
var ldot=str.indexOf(dot)
if (str.indexOf(at)==-1){
return false
}
if (str.indexOf(at)==-1 || str.indexOf(at)==0 ||
str.indexOf(at)==lstr){
return false
}
if (str.indexOf(dot)==-1 || str.indexOf(dot)==0 ||
str.indexOf(dot)==lstr){
return false
}
if (str.indexOf(at,(lat+1))!=-1){
return false
}
if (str.substring(lat-1,lat)==dot ||
str.substring(lat+1,lat+2)==dot){
return false
}
if (str.indexOf(dot,(lat+2))==-1){
return false
}
if (str.indexOf(" ")!=-1){
return false
}
return true
}
