PHP question about adding hyphens to words.

Question

I was wondering if some one enters a tag like ruby on rails is there a way I can add a hyphen to the white spaces between the words for example ruby-on-rails using PHP.

Answer 1

It's as simple as this:

$tag = 'ruby on rails';
$newTag = str_replace(' ', '-', trim($tag));

Answer 2

I suspect you're asking a different question, but lacking more context ...

$string = 'ruby on rails';
$string_with_dashes = str_replace(' ','-',$string);

should get you where you want to go.

Answer 3

$str = 'ruby on rails'; // your entered tag
$myTag = trim($str); // remove extra spaces from beginning and end     
$hyphenTag = str_replace( ' ', '-', $myTag ); // place '-' between words
echo $hyphenTag; // print result

Answer 4

Let me guess

$s = strtolower(trim($s));
$s = str_replace(" ","-",$s);
$s = preg_replace('![^a-z0-9-]!',"",$s);
$s = preg_replace('!\-+!',"-",$s);
