Question

I guess my question is very simple, but I am new to php so I’m lost with this. Basically I would like to replace blanks (” “) by dashes (“-“) and let the anchor text in lowercase, since it will be used as part of the url.

Ex: the anchor text “William Shakespeare” will be converted to “william-shakespeare” to be inserted as part of the url.

<a href="http://site.com/biography/william-shakespeare">William Shakespeare</a>

If the text has only one word will be transformed to lowercase
Ex: “Shakespeare” will just be converted to “shakespeare”.

<a href="http://site.com/tag/shakespeare">Shakespeare</a>

Note: Text translated from the Portuguese language using GoogleTranslate.

Answer 1

No need for a regex. Just use str_replace & strtolower:

strtolower(str_replace(' ', '-', $string));

You should probably also urlencode it, in case you have some wonky characters in there:

urlencode( strtolower(str_replace(' ', '-', $string)) );
