How can I validate an email address using a regular expression?
(79 answers)
Closed 6 years ago.
I have a html context that has usernames, mails and passwords in plain text format. There are two line breaks between information groups.
nickname
mail#example.com
pass
nickname2
mail2#example.com
pass2
I want to get all mails with a comma seperator and set them to a big string variable.
I tried many regexes but could not resolve the problem. Any suggestion to find the true regex will be appreciated.
The pattern:
.+#.+.\.\w+
Example:

If .txt file is not too big (if you have enough memory and time):
$lines = file('mails.txt',FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
function get_emails($val)
{
if (filter_var($val, FILTER_VALIDATE_EMAIL)) {
return $val;
}
}
$emails=array_filter($lines,"get_emails");
//print_r($emails);
$emails_var=join(",",$emails);
//echo $emails_var;
'mails.txt' -> path to your file, of course.

Is there a more efficient way to get email suffix than explode? (PHP)

Closed 3 years ago.
I'm trying to code a PHP script that is given a string with an email address that extracts the username and domain.
For example: username#domain.com -> username | domain.com
I want to take off the "#".
I've tried using trim() but that only works at the start and at the end of a string.
<?php
$email = 'username#domain.com';
$getArray = explode("#",$email);
echo "<pre>";
print_r($getArray);
echo $getArray[0].'<br/>';
echo $getArray[1];
?>

Partially hide email address in PHP

Good Morning Guys! I need to get an e-mail from my database, but I'd like to show it like that:
some*******#hotmail.com
I'd like to show the beginning of my e-mail and then everything after #.
I'm using the following code:
$user_email= "********".substr($linha3['user_email'], -8);
It's working, but sometimes It doesn't appear in a nice way:
********mail.com
May you help me with any solution?
Use RegEx to always match the e-mail username :
echo preg_replace('/.*#/', '***#', 'some_mail#somewhere.net');
$email = $linha3['user_email'];
$email= substr($email, 0, 3).'****'.substr($email, strpos($email, "#"));

How to validate an email address in PHP
(15 answers)
Closed 7 years ago.
I have a php regular expression for email formatting. I used this code below
if ( !(preg_match('/^\w+#[\w.\-]+\.[A-Za-z]{2,3}$/', $email)) ) :
$err_email1 = "<div class = 'error'>Sorry, the email is not formatted properly</div>";
$formerrors = true;
However, it doesn't work when there is a period in the email. i.e. John.Smith#mydomain.com. It works fine with JohnSmith#mydomain.com so I know it's the second period.
How can I modify the code so it works with 2 period? I tried a number of variations but didn't have success.
If you have a good php regular expression site, I am all eyes.
Thanks
Try this
/^([a-z0-9_.-]+)#([\da-z.-]+).([a-z.]{2,6})$/

How can I convert ereg expressions to preg in PHP?
(4 answers)
Closed 3 years ago.
I know there are a lot of questions related to this subject, but after some days of research I didn't find something that could help this particular case, so here it is:
I have replaced the deprecated eregi with preg_match in 2 files of my website, and now the capcha code gives an error on the registration page, even if the code is absolutely correct
On the registration page I have replaced this
function is_valid_username($username) {
if(!eregi("^[a-z0-9]*$", trim(str_replace(" ","",$username)))) {
return 0;
}
with this
if(!preg_match("^[a-z0-9]*$^", trim(str_replace(" ","",$username)))) {
return 0;
}
And in my second file I have replaced this:
if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email)) {
$result = 0;
}
with this
if(!preg_match("^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$^", $email)) {
$result = 0;
}
How can I resolve this issue?
eregi is case-insensitive, so you would need to add the i modifier to the end of your preg_match expression.
Also, ^ denotes the start of the input and you have used it as the delimiter.
So this should be more like the original:
#^[a-z0-9]*$#i
and
#^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$#i
By the way, I don't know what your captcha code requires exactly, but there are easier ways to verify an email address using filter_var().

PHP email validation
I'm working on this website, where I have to make a register form. I made it work, but then my friend told me, that some email domain names does have hyphens in them, like;
test#test-tester.com
Right now my code look like this:
preg_match("/^[a-zA-Z0-9._\-]\w+(\.\w+)*\#\w+(\.[a-zA-Z0-9._-]+)*\.[a-zA-Z.]{2,6}$/", $_POST["email"]
What I can see, this should work, but it still does not allow the hyphen.
Anyone know why?
Regex is always useful, but I prefer to use filter_var to validate emails
http://www.php.net/manual/en/filter.filters.validate.php
if(filter_var($email, FILTER_VALIDATE_EMAIL))
{
print('valid Email!');
}
else
{
print('invalid-email =(');
}
