I need to get the headline of a story and run it through the URL. To do this, I want to search the title in the database and replace each blank space between a word and another with a hyphen. For example: "Newstest" would be "Newstest".

I tried to: 

$titulo_novo = preg_replace('<\W+>', "-", $titulo); 

//$titulo é o titulo vindo do banco de dados

    I got it. It only generated one error: accented characters (ã, ó, etc.) need to be normal, for example, will be replaced by ; ion by cao...

The solution is very simple using preg_replace. If you just wanted to put the title as URL by converting spaces to hyphens, just add:

$titulo_novo = preg_replace('/[ -]+/' , '-' , $titulo);

But if you want something complete that also removes and converts the accents, you can use:

$titulo = "Notícia Com Ácêntös";
$titulo_novo = strtolower( preg_replace("[^a-zA-Z0-9-]", "-", 
strtr(utf8_decode(trim($titulo)), utf8_decode("áàãâéêíóôõúüñçÁÀÃÂÉÊÍÓÔÕÚÜÑÇ"),
"aaaaeeiooouuncAAAAEEIOOOUUNC-")) );

echo $titulo_novo; //pode remover essa linha, é só pra mostrar como ficou.

    It worked perfectly! Thank you Victor Gomes!

  • The ereg_* was depreciated, traded there for preg_replace() :P

  • Thanks @rray, corrected ;)
