PHP function to make slug (URL string)
PhpInternationalizationSlugPhp Problem Overview
I want to have a function to create slugs from Unicode strings, e.g. gen_slug('Andrés Cortez') should return andres-cortez. How should I do that?
Php Solutions
Solution 1 - Php
Instead of a lengthy replace, try this one:
public static function slugify($text, string $divider = '-')
{
// replace non letter or digits by divider
$text = preg_replace('~[^\pL\d]+~u', $divider, $text);
// transliterate
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
// remove unwanted characters
$text = preg_replace('~[^-\w]+~', '', $text);
// trim
$text = trim($text, $divider);
// remove duplicate divider
$text = preg_replace('~-+~', $divider, $text);
// lowercase
$text = strtolower($text);
if (empty($text)) {
return 'n-a';
}
return $text;
}
This was based off the one in Symfony's Jobeet tutorial.

Update
Since this answer is getting some attention, I'm adding some explanation.
The solution provided will essentially replace everything except A-Z, a-z, 0-9, & - (hyphen) with - (hyphen). So, it won't work properly with other unicode characters (which are valid characters for a URL slug/string). A common scenario is when the input string contains non-English characters.
Only use this solution if you're confident that the input string won't have unicode characters which you might want to be a part of output/slug.
Eg. "नारी शक्ति" will become "----------" (all hyphens) instead of "नारी-शक्ति" (valid URL slug).
Original Answer
How about...
$slug = strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $string)));
?
Solution 3 - Php
If you have intl extension installed, you can use Transliterator::transliterate function to create a slug easily.
$string = 'Namnet på bildtävlingen';
$rules = <<<'RULES'
:: Any-Latin;
:: NFD;
:: [:Nonspacing Mark:] Remove;
:: NFC;
:: [^-[:^Punctuation:]] Remove;
:: Lower();
[:^L:] { [-] > ;
[-] } [:^L:] > ;
[-[:Separator:]]+ > '-';
RULES;
$slug = \Transliterator::createFromRules($rules)
->transliterate( $string );
echo $slug; // namnet-pa-bildtavlingen
Note that this solution works whatever the alphabet and is highly flexible.
Solution 4 - Php
Note: I have taken this from wordpress and it works!!
Use it like this:
echo sanitize('testing this link');
Code
//taken from wordpress
function utf8_uri_encode( $utf8_string, $length = 0 ) {
$unicode = '';
$values = array();
$num_octets = 1;
$unicode_length = 0;
$string_length = strlen( $utf8_string );
for ($i = 0; $i < $string_length; $i++ ) {
$value = ord( $utf8_string[ $i ] );
if ( $value < 128 ) {
if ( $length && ( $unicode_length >= $length ) )
break;
$unicode .= chr($value);
$unicode_length++;
} else {
if ( count( $values ) == 0 ) $num_octets = ( $value < 224 ) ? 2 : 3;
$values[] = $value;
if ( $length && ( $unicode_length + ($num_octets * 3) ) > $length )
break;
if ( count( $values ) == $num_octets ) {
if ($num_octets == 3) {
$unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]) . '%' . dechex($values[2]);
$unicode_length += 9;
} else {
$unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]);
$unicode_length += 6;
}
$values = array();
$num_octets = 1;
}
}
}
return $unicode;
}
//taken from wordpress
function seems_utf8($str) {
$length = strlen($str);
for ($i=0; $i < $length; $i++) {
$c = ord($str[$i]);
if ($c < 0x80) $n = 0; # 0bbbbbbb
elseif (($c & 0xE0) == 0xC0) $n=1; # 110bbbbb
elseif (($c & 0xF0) == 0xE0) $n=2; # 1110bbbb
elseif (($c & 0xF8) == 0xF0) $n=3; # 11110bbb
elseif (($c & 0xFC) == 0xF8) $n=4; # 111110bb
elseif (($c & 0xFE) == 0xFC) $n=5; # 1111110b
else return false; # Does not match any model
for ($j=0; $j<$n; $j++) { # n bytes matching 10bbbbbb follow ?
if ((++$i == $length) || ((ord($str[$i]) & 0xC0) != 0x80))
return false;
}
}
return true;
}
//function sanitize_title_with_dashes taken from wordpress
function sanitize($title) {
$title = strip_tags($title);
// Preserve escaped octets.
$title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
// Remove percent signs that are not part of an octet.
$title = str_replace('%', '', $title);
// Restore octets.
$title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);
if (seems_utf8($title)) {
if (function_exists('mb_strtolower')) {
$title = mb_strtolower($title, 'UTF-8');
}
$title = utf8_uri_encode($title, 200);
}
$title = strtolower($title);
$title = preg_replace('/&.+?;/', '', $title); // kill entities
$title = str_replace('.', '-', $title);
$title = preg_replace('/[^%a-z0-9 _-]/', '', $title);
$title = preg_replace('/\s+/', '-', $title);
$title = preg_replace('|-+|', '-', $title);
$title = trim($title, '-');
return $title;
}
Solution 5 - Php
It is always a good idea to use existing solutions that are being supported by a lot of high-level developers. The most popular one is https://github.com/cocur/slugify. First of all, it supports more than one language, and it is being updated.
If you do not want to use the whole package, you can copy the part that you need.
Solution 6 - Php
Here is an other one, for example " Title with strange characters ééé A X Z" becomes "title-with-strange-characters-eee-a-x-z".
/**

*
* @param string $string the string to transform.
*
* @return string the resulting slug.
*/
public static function createSlug($string) {
$table = array(
'Š'=>'S', 'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',

// -- Remove duplicated spaces
$stripped = preg_replace(array('/\s{2,}/', '/[\t\n]/'), ' ', $string);
// -- Returns the slug
return strtolower(strtr($string, $table));
}
Solution 7 - Php
Don't use preg_replace for this. There's a php function built just for the task: strtr() http://php.net/manual/en/function.strtr.php
Taken from the comments in the above link (and I tested it myself; it works:
function normalize ($string) {
$table = array(
'Š'=>'S', 'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',
'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o',
'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b',
'ÿ'=>'y', 'Ŕ'=>'R', 'ŕ'=>'r',
);
return strtr($string, $table);

Solution 10 - Php
There are already many answers here, so I almost don't want to add another one, but none of the functions did everything I needed.
The best basis for me was function number 3 where their speed was compared. I added/fixed some replacements so
'is just deleted,.is replaced by-,αis replaced bya,ẞis replaced byb,Ł(and similar) is replaced byLinstead ofK, and€and$signs are replaced witheurandusdrespectively (add more on necessity).
Optionally you can add '&' => '-and-', but SEO advises against usage of conjunctions (#8), so I left it out for my use-case. (this function doesn't strip existing ands and ors from the string though)
I also added a line of code to fix double dash in this weird string I came up with, as well as an optional parameter to limit slug's length.
Code
<?php
function slugify($text, $length = null)

It also works for OP's case for converting 'Andrés Cortez' to 'andres-cortez' and all other examples I have found in this thread, except this character which is beyond me: 𐐷.

Solution 12 - Php
I am using:
function slugify($text)
{
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
return strtolower(preg_replace('/[^A-Za-z0-9-]+/', '-', $text));
}
Only fallback is that Cyrillic characters will not be converted, and I am searching now for solution that is not long str_replace for every single Cyrillic character.
Solution 13 - Php
The most elegant way I think is using a Behat\Transliterator\Transliterator.
I need to extends this class by your class because it is an Abstract, some like this:
<?php
use Behat\Transliterator\Transliterator;
class Urlizer extends Transliterator
{
}
And then, just use it:
$text = "Master Ápiu";
$urlizer = new Urlizer();
$slug = $urlizer->transliterate($slug, "-");
echo $slug; // master-apiu
Of course you should put this things in your composer as well.
composer require behat/transliterator
More info here https://github.com/Behat/Transliterator

You could have a look at Normalizer::normalize(), see here. It just needs to load the intl module for PHP
Solution 15 - Php
What about using something that is already implemented in Core?
//Clean non UTF-8 characters
Mage::getHelper('core/string')->cleanString($str)
Or one of the core url/ url rewrite methods..
Solution 16 - Php
I wrote this based on Maerlyn's response. This function will work regardless of the character encoding on the page. It also won't turn single quotes in to dashes :)
function slugify ($string) {
$string = utf8_encode($string);
$string = iconv('UTF-8', 'ASCII//TRANSLIT', $string);
$string = preg_replace('/[^a-z0-9- ]/i', '', $string);
$string = str_replace(' ', '-', $string);
$string = trim($string, '-');
$string = strtolower($string);
if (empty($string)) {
return 'n-a';
}
return $string;
}
Solution 17 - Php
On my localhost everything was ok, but on server it helped me “set_locale” and “utf-8” at “mb_strtolower”.
<?
setlocale( LC_ALL, "en_US.UTF8" );
function slug( $str, $char = "-", $tf = "lowercase" )
{
$str = iconv( "utf-8", "us-ascii//translit//ignore", $str ); // transliterate
$str = str_replace( "'", "", $str ); // remove “'” generated by iconv
$str = preg_replace( "~[^a-z0-9]+~ui", $char, $str ); // replace unwanted by single “-”
$str = trim( $str, $char ); // trim “-”
if( $tf == "lowercase" ) $str = mb_strtolower( $str, "utf-8" ); // lowercase
elseif( $tf == "uppercase" ) $str = mb_strtoupper( $str, "utf-8" );
return $str;
}
?>

This may be a way to do it too. Inspired from these links Experts-exchange and alinalexander
function slugifier($txt){
/* Get rid of accented characters */
$search = explode(",","ç,æ,œ,á,é,í,ó,ú,à,è,ì,ò,ù,ä,ë,ï,ö,ü,ÿ,â,ê,î,ô,û,å,e,i,ø,u");
$replace = explode(",","c,ae,oe,a,e,i,o,u,a,e,i,o,u,a,e,i,o,u,y,a,e,i,o,u,a,e,i,o,u");
$txt = str_replace($search, $replace, $txt);
/* Lowercase all the characters */
$txt = strtolower($txt);
/* Avoid whitespace at the beginning and the ending */
$txt = trim($txt);
/* Replace all the characters that are not in a-z or 0-9 by a hyphen */
$txt = preg_replace("/[^a-z0-9]/", "-", $txt);
/* Remove hyphen anywhere it's more than one */
$txt = preg_replace("/[\-]+/", '-', $txt);
return $txt;
}

For standard alphanumeric english - nothing complicated.
/**
* Update the provided string to a slug-safe format.
*
* @param string $string
* @return string
*/
function slugify($string)
{
return strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $string), '-'));
}

Since gTLDs and IDNs are becoming more and more used I cannot see why URL shouldn't contain Andrés.
Just rawurlencode $URL you want instead. Most browsers show UTF-8 characters in URLs (not some ancient IE6 maybe) and bit.ly / goo.gl can be used to make it short in cases like Russian and Arabic if need may be for ad purposes or just write them in ads like user would write them on browser URL.
Only difference is spaces " " it might be good idea to replace them with "-" and "/" if you don't want to allow those.
<?php
function slugify($url)
{
$url = trim($url);
$url = str_replace(" ","-",$url);
$url = str_replace("/","-slash-",$url);
$url = rawurlencode($url);
}
?>
Url as encoded http://www.hurtta.com/RU/%D0%9F%D1%80%D0%BE%D0%B4%D1%83%D0%BA%D1%82%D1%8B/

For me this variant is perfect, also it change & to and. Here is code:
function dSlug($string) {
return strtolower(trim(preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1',htmlentities(preg_replace('/[&]/', ' and ', $title), ENT_QUOTES, 'UTF-8')), ENT_QUOTES, 'UTF-8')), '-'));
}`

if your slug contain only A-Za-z0-9- then it is ok for you
function sanitize_slug($text)

$text = preg_replace('/[^A-Za-z0-9-]+/', '-', $text);
$text = trim($text, '-');
$text = preg_replace('~-+~', '-', $text);
return $text;
}

$oldLocale = setlocale(LC_ALL, '0');
setlocale(LC_ALL, 'en_US.UTF-8');
$clean = iconv('UTF-8', 'ASCII//TRANSLIT', $string);
$clean = preg_replace("/[^a-zA-Z0-9\/_|+ -]/", '', $clean);
$clean = strtolower($clean);
$clean = preg_replace("/[\/_|+ -]+/", $delimiter, $clean);
$clean = trim($clean, $delimiter);
setlocale(LC_ALL, $oldLocale);
return $clean;
