Trying to make a url generator from a title

Hi there,

I have been trying to make a generator that will take a title and strip out all the special characters like !"£$ etc...

I have used strtolower and str_replace in a chain with each character but it is inconsistent and will not strip everything like ~.

Is there anything out there that can help with something like this,  I have had a bit of a search but nothing had turned up yet.



Try using the url_title from the url helper: https://www.codeigniter.com/user_guide/h...#url_title

I don't know which version Codeigniter you are using but if you're using 3.x, you can try URL helper function: url_title. You can reach the references with the link below.


Hope this helps

First of all we need to strip all special characters and punctuation away. 
This is easily accomplished with something like:

function toAscii($str) {
$clean = preg_replace("/[^a-zA-Z0-9/_|+ -]/", '', $str);
$clean = strtolower(trim($clean, '-'));
$clean = preg_replace("/[/_|+ -]+/", '-', $clean);

return $clean;

Second option
setlocale(LC_ALL, 'en_US.UTF8');
function toAscii($str) {
$clean = iconv('UTF-8', 'ASCII//TRANSLIT', $str);
$clean = preg_replace("/[^a-zA-Z0-9/_| -]/", '', $clean);
$clean = strtolower(trim($clean, '-'));
$clean = preg_replace("/[/_| -]+/", '-', $clean);

return $clean;
