[PHP] What's a good regex to validate an email address? ;)

[Daevid Vincent]

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                                    
}
