Replace number and email with XXXX in a sentence using jQuery - php

Question

I'd like to replace the numbers and email from the sentences.
Example
$message = "Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com".
Output:
Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com
I want the Output to be like this:
Output:
Hi this is john, my personal no is XXXXXXX789 and my email address is XXXX#gmail.com
But I'm currently getting like this :
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX#gmail.com
function which I'm using now
function numbers1($str)
{
if(($until = strpos($str, '#')) !== false)
{
$str = str_repeat('X', $until) . substr($str, $until);
}
}
Thanks in advance.

Answer 1

try preg_replace()
$str = "Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com";
$replacements[1] = 'X';
$replacements[0] = 'XXXX#';
echo preg_replace(array('/[0-6]/', '/[ a-z]{0,4}+#/'), $replacements, $str);
output :- Hi this is john, my personal no is XXXXXXX789 and my email address is XXXX#gmail.com

Answer 2

$message = "Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com";
$arr = explode(" ", $message);
foreach($arr as $key=>$val)
{
if(!preg_match ("/[^0-9]/", $val))
{
$val_new = "XXXXXXX".substr($val, -3);
$arr[$key] = $val_new;
}
else if(strpos($val, "#")>0)
{
$arr_email = explode("#", $val);
$arr_email[0] = "XXXX";
$val_new = implode("#", $arr_email);
$arr[$key] = $val_new;
}
}
$new_msg = implode(" ", $arr);
echo $new_msg;
UPDATE 2 :
$message = "Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com";
$arr = explode(" ", $message);
foreach($arr as $key=>$val)
{
if(!preg_match ("/[^0-9]/", $val))
{
$val_new = "XXXXXXX".substr($val, -3);
$arr[$key] = $val_new;
}
else if(preg_match ("/^[a-z0-9_\+-]+(\.[a-z0-9_\+-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*\.([a-z]{2,4})$/", $val))
{
$arr_email = explode("#", $val);
$arr_email[0] = "XXXX";
$val_new = implode("#", $arr_email);
$arr[$key] = $val_new;
}
}
$new_msg = implode(" ", $arr);
echo $new_msg;

Answer 3

You're asking how to do this using jQuery, however your sample code is written in PHP. I'll answer your question with a PHP snippet as well.
The reason why your function isn't working is because you're replacing pretty much everything from the beginning of the string up to the position where the first '#' is found. Then you're adding as many 'X' as characters are until that position, followed by the rest of the string. To complicate things more, this won't work if two or more email addresses are found in your string.
This should do. You might need to tweak the regexes for both the phone numbers and the email addresses, though:
$message = "Hi this is john, my personal no is 1213456789 and my email address is john#gmail.com";
// get all phone numbers
preg_match('/\d{3,}/s', $message, $phones);
// get all email addresses
preg_match('/[a-z.-]+#[a-z.-]+/s', $message, $emails);
foreach ($phones as $phone)
{
$message = str_replace($phone, str_repeat('X', strlen($phone) - 3) . substr($phone, -3), $message);
}
foreach ($emails as $email)
{
$parts = explode('#', $email);
$message = str_replace($email, str_repeat('X', strlen($parts[0])) . '#' . $parts[1], $message);
}
// Hi this is john, my personal no is XXXXXXX789 and my email address is XXXX#gmail.com
echo $message;
