PHP mb_ereg_replace not replacing while preg_replace works as intended
I am trying to replace in a string all non word characters with empty string expect for spaces and the put together all multiple spaces as one single space.
Following code does this.
$cleanedString = preg_replace('/[^\w]/', ' ', $name);
$cleanedString = preg_replace('/\s+/', ' '开发者_运维问答, $cleanedString);
But when I am trying to use mb_ereg_replace nothing happens.
$cleanedString = mb_ereg_replace('/[^\w]/', ' ', $name);
$cleanedString = mb_ereg_replace('/\s+/', ' ', $cleanedString);
$cleanedString is same as of that if $name in the above case. What am I doing wrong?
mb_ereg_replace
doesn't use separators. You may or may not also have to specify the encoding before.
mb_regex_encoding("UTF-8");
//regex could also be \W
$cleanedString = mb_ereg_replace('[^\w]', ' ', $name);
$cleanedString = mb_ereg_replace('\s+', ' ', $cleanedString);
function create_slug_html($string, $ext='.html'){
$replace = '-';
$string=strtolower($string);
$string=trim($string);
mb_regex_encoding("UTF-8");
//regex could also be \W
$string= mb_ereg_replace('[^\w]', ' ', $string);
$string= mb_ereg_replace('\s+', ' ', $string);
//remove query string
if(preg_match("#^http(s)?://[a-z0-9-_.]+\.[a-z]{2,4}#i",$string)){
$parsed_url = parse_url($string);
$string = $parsed_url['host'].' '.$parsed_url['path'];
//if want to add scheme eg. http, https than uncomment next line
//$string = $parsed_url['scheme'].' '.$string;
}
//replace / and . with white space
$string = preg_replace("/[\/\.]/", " ", $string);
// $string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
//remove multiple dashes or whitespaces
$string = preg_replace("/[\s-]+/", " ", $string);
//convert whitespaces and underscore to $replace
$string = preg_replace("/[\s_]/", $replace, $string);
//limit the slug size
$string = substr($string, 0, 200);
//slug is generated
return ($ext) ? $string.$ext : $string;
}
please check is it ok and support english and unicode
The input is not Multi-Byte hence the mb
function fails.
