I have an email address that could either be
$email = "x#example.com"; or $email="Johnny <x#example.com>"
I want to get
$handle = "x"; for either version of the $email.
How can this be done in PHP (assuming regex). I'm not so good at regex.
Thanks in advance
Use the regex <?([^<]+?)# then get the result from $matches[1].
Here's what it does:
<? matches an optional <.
[^<]+? does a non-greedy match of one or more characters that are not ^ or <.
# matches the # in the email address.
A non-greedy match makes the resulting match the shortest necessary for the regex to match. This prevents running past the #.

Here is a complete PHP solution based on marcog's answer
function extract_email($email_string) {
preg_match("/<?([^<]+?)#([^>]+?)>?$/", $email_string, $matches);
return $matches[1] . "#" . $matches[2];
}
echo extract_email("ice.cream.bob#gmail.com"); // outputs ice.cream.bob#gmail.com
echo extract_email("Ice Cream Bob <ice.cream.bob#gmail.com>"); // outputs ice.cream.bob#gmail.com
Just search the string using this basic email-finding regex: \b[A-Z0-9._%+-]+#[A-Z0-9.-]+.[A-Z]{2,4}\b
It will match any email in any text, and in your first string it will match the whole string, and in the second, only the part of the string that is e-mail.
To quickly learn regexp this is the best place: http://www.regular-expressions.info
$email = 'x#gmail.com';
preg_match('/([a-zA-Z0-9\-\._\+]+#[a-z0-9A-Z\-\._]+\.[a-zA-Z]+)/', $email, $regex);
$handle = array_shift(explode('#', $regex[1]));
Try that (Not tested)

i want to make regex to detect this format image(numeric, string). ex: image(100, 'test').
i have tried this one, but just detect the image(numeric)
/image\((\d+)\)/
Any help with second parameter and the ,?
Also how i can get the second parameter?
You can try the following pattern:
/image\(\d+,\s*'.+?'\)/
I removed the capture group since it would be not needed if using the regex for validation only.
Demo
If you want to capture the number and text, then use capture groups:
$input = "code image(123, 'meh') more code";
if (preg_match("/image\((\d+),\s*'(.+?)'\)/", $input, $m)) {
echo "match";
}
$number = $m[1];
$text = $m[2];
Try this:
image\((\d+), '(.+?)'\)
The . matches anything and the rest is pretty much self-explanatory. Group 1 is your number, group 2 is the string.
You can try this one:
image\(\s*\d+\s*\,\s*'.*'\s*\)
I'm trying to replace the domain name of email addresses, between # and . with ***
For example:
$email1 = info#mytestdomain.com
$email2 = info#mytestdomain.net
Need to be become
$email1 = info#***.com
$email2 = info#***.net
I know I can use the PHP preg_replace function but I'm not sure what regex I need to use in my case. So my question is, which regex should I use in my case to replace everything between # and . with ***?
Thanks
You can use this assertion based regex.
$eml = preg_replace('/#\K[^.]+/', '***', $eml);
Live Demo
Live demo
$email1 = "info#mytestdomain.com";
echo preg_replace("/(.*#)([^\.]+)(\..*)/","$1***$3",$email1);
Output:
info#***.com
You could use a positive lookahead also.
$email1 = "info#mytestdomain.com";
echo preg_replace("/[^#]+(?=\.)/","***",$email1);
Pattern Explanation:
[^#]+(?=\.) Matches any character but not of # one or more times only if the characters are followed by a literal dot.
I have a string as
$email_string='Aslam Doctor <aslam.doctor#gmail.com>';
From which I want to extract Name & Email using PHP? so that I can get
$email='aslam.doctor#gmail.com';
$name='Aslam Doctor'
Thanks in advance.
As much as people will probably recommend regular expression I'd say use explode().
Explode splits the string up in several substrings using any delimiter.
In this case I use ' <' as a delimiter to immediately strip the whitespace between the name and e-mail.
$split = explode(' <', $email_string);
$name = $split[0];
$email = rtrim($split[1], '>');
rtrim() will trim the '>' character from the end of the string.
Using explode + list:
$email_string = 'Aslam Doctor <aslam.doctor#gmail.com>';
list($name, $email) = explode(' <', trim($email_string, '> '));
If you can use the IMAP extension, the imap_rfc822_parse_adrlist function is all you need.

text variable have one paragraph. two emails are included there. using extract_emails_from_string() function we extracts those mails from that paragraph.
preg_match_all function will return all matching strings with the regular expression from inputs.
function extract_emails_from_string($string){
preg_match_all("/[\._a-zA-Z0-9-]+#[\._a-zA-Z0-9-]+/i", $string, $matches);
return $matches[0];
}
$text = "Please be sure to answer the Please arun1#email.com be sure to answer the Please be sure to answer the Please be sure to answer the Please be sure to answer the Please be sure to answer the Please be sure to answer the arun#email.com";
$emails = extract_emails_from_string($text);
print(implode("\n", $emails));
This is what I use - works for email addresses with and without the angle bracket formatting. Because we are searching from right to left, this also works for those weird instances where the name segment actually contains the < character:
$email = 'Aslam Doctor <aslam.doctor#gmail.com>';
$address = trim(substr($email, strrpos($email, '<')), '<>');
I have a regex email pattern and would like to strip all but pattern-matched characters from the string, in a short I want to sanitize string...
I'm not a regex guru, so what I'm missing in regex?
<?php
$pattern = "/^([\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+\.)*[\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+#((((([a-z0-9]{1}[a-z0-9\-]{0,62}[a-z0-9]{1})|[a-z])\.)+[a-z]{2,6})|(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?)$/i";
$email = 'contact<>#domain.com'; // wrong email
$sanitized_email = preg_replace($pattern, NULL, $email);
echo $sanitized_email; // Should be contact#domain.com
?>
Pattern taken from: http://fightingforalostcause.net/misc/2006/compare-email-regex.php (the very first one...)
You cannot filter and match at the same time. You'll need to break it up into a character class for stripping invalid characters and a matching regular expression which verifies a valid address.
$email = preg_replace($filter, "", $email);
if (preg_match($verify, $email)) {
// ok, sanitized
return $email;
}
For the first case, you want to use a negated character class /[^allowedchars]/.
For the second part you use the structure /^...#...$/.
Have a look at PHPs filter extension. It uses const unsigned char allowed_list[] = LOWALPHA HIALPHA DIGIT "!#$%&'*+-=?^_\{|}~#.[]";` for cleansing.
And there is the monster for validation: line 525 in http://gcov.php.net/PHP_5_3/lcov_html/filter/logical_filters.c.gcov.php - but check out http://www.regular-expressions.info/email.html for a more common and shorter variant.
i guess filter_var php function can also do this functionality, and in a cleaner way.
Have a look at:
http://www.php.net/manual/en/function.filter-var.php
example:
$email = "chris#exam\\ple.com";
$cleanEmail = filter_var($email, FILTER_SANITIZE_EMAIL); // chris#example.com
I have such text:
<Neednt#email.com> If you do so, please include this problem report.
<Anotherneednt#email.com> You can delete your
own
text from the attached returned message.
The mail system
<Some#Mail.net>: connect to *.net[82.*.86.*]: Connection timed
out
I have to parse email from it. Could you help me with this job?
upd
There could be another email addresses in <%here%>. There should be connection between 'The mail system' text. I need in email which goes after that text.
Considering this text is stored in $text, what about this :
$matches = array();
if (preg_match('/<([^>]+)>/', $text, $matches)) {
var_dump($matches[1]);
}
Which gives me :
string 'Some#Mail.net' (length=13)
Basically, I used a pretty simple regex, that matches :
a < character
anything that's not a > character : [^>]
at least one time : [^>]+
capturing it : ([^>]+)
a > character
So, it captures anything that's between < and >.
Edit after comments+edit of the OP :
If you only want the e-mail address that's after The mail system, you could use this :
$matches = array();
if (preg_match('/The mail system\s*<([^>]+)>/', $text, $matches)) {
var_dump($matches[1]);
}
In addition to what I posted before, this expects :
The string The mail system
Any number of white-characters : \s*
You want to use preg_match() and looking at this input it should be simple:
<?php
if (preg_match('/<([^>]*?#[^>]*>/', $data, $matches)) {
var_dump($matches); // specifically look at $matches[1]
}
There are other patterns that would match it, you don't have to stick to that same pattern. The '<' and '>' in your input are helpful here.
