Since I ve Seen a lot of methods here but I ve found a simplest method for myself Maybe it will help someone    slug   strtolower preg replace     a-zA-Z0-9 -        preg replace    s      -    string

Since gTLDs and IDNs are becoming more and more used I cannot see why URL shouldn t contain Andr  s   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    lt  php function slugify  url         url   trim  url         url   str replace      -   url        url   str replace      -slash-   url        url   rawurlencode  url       gt    Url as encoded  http   www hurtta com RU  D0 9F D1 80 D0 BE D0 B4 D1 83 D0 BA D1 82 D1 8B   Url as written http   www hurtta com RU

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   amp  -  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   quot            quot  will become  quot ---------- quot   all hyphens  instead of  quot     -      quot   valid URL slug   Original Answer How about     slug   strtolower trim preg replace     A-Za-z0-9-       -    string

If you have intl extension installed  you can use Transliterator  transliterate function to create a slug easily    lt  php  string    Namnet p   bildt  vlingen    slug    Transliterator  createFromRules          Any-Latin             NFD               Nonspacing Mark   Remove             NFC               Punctuation   Remove             Lower              Separator    gt    -          - gt transliterate   string    echo  slug     namnet-pa-bildtavlingen   gt

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

User · Answer

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    lt  php use Behat Transliterator Transliterator   class Urlizer extends Transliterator       And then  just use it    text    Master   piu    urlizer   new Urlizer     slug    urlizer- gt 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
