The regular expression
[a-zA-Z0-9_-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+
does not compile.
When a dash is used in a character class it indicates a range.
_-. is not a valid range.
A corrected version could be
[.+a-zA-Z0-9_-]+@[a-zA-Z0-9-]+.[a-zA-Z]+
or
[-a-zA-Z0-9_.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+
When the dash is moved to the beginning or end of the character class it is automatically not part of a range and instead does a literal match on the dash character.
Here are my sample scripts:
email_bad.php:
!/usr/bin/php
email_fixed.php:
!/usr/bin/php
Doesn't seem to allow PHP tags. Here's another try on those sample scripts:
Here are my sample scripts:
email_bad.php:
errorreporting( EALL );
function isvalidemail( $email ) { if( pregmatch( "/[a-zA-Z0-9-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+/", $email ) > 0 ) return true; else return false; }
$emails = array( 'br0k3n', 'fred_dred@aol.com', 'fred-dred@aol.com', 'fred.dred@aol.com', 'fred+dred@aol.com' );
foreach( $emails as $email ) { echo $email . ' is' . ( isvalidemail( $email ) ? '' : ' not' ) . " valid\n"; }
email_fixed.php:
errorreporting( EALL );
function isvalidemail( $email ) { return pregmatch( '/[.+a-zA-Z0-9-]+@[a-zA-Z0-9-]+.[a-zA-Z]+/', $email ); }
$emails = array( 'br0k3n', 'fred_dred@aol.com', 'fred-dred@aol.com', 'fred.dred@aol.com', 'fred+dred@aol.com' );
foreach( $emails as $email ) { echo $email . ' is' . ( isvalidemail( $email ) ? '' : ' not' ) . " valid\n"; }
Simplest way. PHP5 only
http://www.w3schools.com/php/filtervalidateemail.asp
http://snipplr.com/view/8844/rfc822-compliant-email-address-validator/
http://snipplr.com/view/11616/rfccompliant-email-address-validator/
And check out a head-to-head of free validators here: http://www.dominicsayers.com/isemail/
From w3schools - http://www.w3schools.com/php/filtervalidateemail.asp
To check whether an email address actually exists on the mailserver, use the [PHP SMTP Email Validation][1] class.
[1] http://code.google.com/p/php-smtp-email-validation/ "PHP SMTP Email Validation"
The correct link:
To check whether an email address actually exists on the mailserver, use the PHP SMTP Email Validation class.
Simplified reg ex for this: /\S+@\S+.\D+/
Try this: validemail.org
Here is another SMTP mail validation function in php: http://snipplr.com/view/25505/validate-emails-with-smtp-and-php/
You can try the next: function checkemailaddress($email) { // First, we check that there's one @ symbol, // and that the lengths are right. if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) { // Email invalid because wrong number of characters // in one section or wrong number of @ symbols. return false; } // Split it into sections to make life easier $emailarray = explode("@", $email); $localarray = explode(".", $emailarray[0]); for ($i = 0; $i < sizeof($localarray); $i++) { if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_
{|}~-][A-Za-z0-9!#$%& ↪'*+/=?^_{|}~.-]{0,63})|(\"[^(\|\")]{0,62}\"))$", $local_array[$i])) { return false; } } // Check if domain is IP. If not, // it should be valid domain name if (!ereg("^[?[0-9.]+]?$", $email_array[1])) { $domain_array = explode(".", $email_array[1]); if (sizeof($domain_array) < 2) { return false; // Not enough parts to domain } for ($i = 0; $i < sizeof($domain_array); $i++) { if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])| ↪([A-Za-z0-9]+))$", $domain_array[$i])) { return false; } } } return true; }Also you can search for demo email php form and look a right code
apart from the little typos/errors noted by the others, this is a great snippet. Short, Sweet, and very useful. thanks and good work, dude - keep it up!!

+1 for @jfherring
The code is unnecessarily verbose. There's no need to explicitly return true/false with an if/else. This body will suffice:
return (pregmatch("/[a-zA-Z0-9-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+/", $email) > 0);
Way too much of an overkill. You should be using PHP's filter_var. Example below:
if(!filtervar($email, FILTERVALIDATE_EMAIL)) { // Error message here }
@NaRzY - that code is nearly 3 years old.
there is no reason to use if/else statement you can simply return preg_match(); http://snipplr.com/view/45702/check-for-valid-email-address-rfc/
http://snipplr.com/view/45716/check-for-valid-email-address-rfc/
As many have noted, using custom regular expressions isn't necessary when filter_var options are available.
+1 to housecor as well.
filtervar($email, FILTERVALIDATE_EMAIL);
This either returns the email or false.
http://www.snipplr.com/view/58338/validate-email-and-domain/
http://snipplr.com/view/40841/email-validation-ipv6-version/ && http://snipplr.com/view/40842/email-validation-ipv4-version/
both would do a better job, however, unless you are forced due to legacy reasons, I would use php's built in filtervar() --> http://us.php.net/manual/en/function.filter-var.php ( some people are still running pre 5.2 versions of php )
you should also check for a valid DNS
function validate_email($email){
$exp = "^[a-z\'0-9]+([.-][a-z\'0-9]+)*@([a-z0-9]+([.-][a-z0-9]+))+$";
if(eregi($exp,$email)){
}else{
}
}
