my PHP validation regex not working and i don't understand why. My code returning: 'Failure'. I checked my regex pattern and it is valid: https://regex101.com/r/2Is2L5/2
Phone value is: +7 (555) 555–55–55
if(preg_match('/^\+?\d{1,3}\s*\(\d{3}\)\s*\d{3}[-–•\s]?\d{2}[-–•\s]?\d{2}$/', $_GET['userPhone'])) {
echo 'Success';
}
else{
echo 'Failure';
}
Please help!
The following works for me:
$ cat a.php
<?php
if(preg_match('/^\+?\d{1,3}\s*\(\d{3}\)\s*\d{3}[-–•\s]?\d{2}[-–•\s]?\d{2}$/u', '+7 (555) 555–55–55')) {
echo 'Success';
}
else{
echo 'Failure';
}
?>
$ php a.php
Success
Notice the /u modifier at the end. According to the documentation:
u (PCRE_UTF8) This modifier turns on additional functionality of PCRE that is incompatible with Perl. Pattern and subject strings are treated as UTF-8. An invalid subject will cause the preg_* function to match nothing; an invalid pattern will trigger an error of level E_WARNING. Five and six octet UTF-8 sequences are regarded as invalid since PHP 5.3.4 (resp. PCRE 7.3 2007-08-28); formerly those have been regarded as valid UTF-8.
