Here is my regex to exclude special character other then allowing few like (-,%,:,@). I want to allow / also but getting issue
return preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%:@&-]/s', '', $string);
this works fine for listed special character, but
return preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%\\:&-]/s', '', $string);
does not filter l chracter to.
Here is the link to test:
where it does not allow \\ in url. I want to dispaly URL as usual
You're making a mistake in entering http:// by http:\\ also your regex needs to include / in exclusion list. This should work:
function clean($string) {
// Replaces all spaces with hyphens.
$string = str_replace(' ', '-', $string);
// Removes special chars.
return preg_replace('~[^\w %\[\].()%\\:@&/-]~', '', $string);
}
$d = clean("this was http://nice readlly n'ice 'test for@me to") ;
echo $d; // this-was-http://nice-readlly-nice-test-for@me-to
