Little preg_replace trouble.

[strago]

$titleurl = preg_replace('/[^a-zA-Z0-9_ -%]/', '-', $d);
$titleurl = preg_replace('/[ ]/', '-', $titleurl);

 

How do you add to this to replace

 

---- with -

--- with -

-- with -

 

and remove quotes?

 

How do you remove a - if it's at the very end of $titleurl. For example, replace My-iPhone- with My-iPhone

You can have a simple pattern match one or more hyphens and replace with a single hyphen:

 

$str = preg_replace('/-+/', '-', $str);

 

Then to remove any leading or trailing hyphens, just run it through trim:

 

$str = trim($str, '-');

Sorry, missed "adapt this" -

 

$titleurl = preg_replace('/[^a-zA-Z0-9_ -%]/', '-', $d);
$titleurl = preg_replace('/-+/', '-', $titleurl);
$titleurl = trim($titleurl, '-');
