I have a problem with loooong urls submitted in my guestbook/blog.
I would like to replace the loong urls entered into the form with something like:
<a href="{real url}">{short url}</a>
I would like the short url to be ended with “…” if it’s longer than X characters. I’ve tried to use preg_replace but that will simply cut the link based on the regular expression.
$urlPattern = "/(https?:\/\/)?(www.)?([-a-z0-9]*[a-z0-9]\.)(\bcom\b|\bbiz\b|\bgov\b|\bmil\b|\bnet\b|\borg\ b|[a-z][a-z]\.[a-z][a-z])\/?([a-zA-Z0-9]*)?([a-zA-Z0-9\.\?=\/&]*)?/";
$textNew = preg_replace($urlPattern,"<a href=\"$1$2$3$4/$5$6\" >$2$3$4/$5</a>", $textOriginal);
This results in (example):
<a href="http://www.example1.com">www.example1.com</a>
<a href="http://www.example2.com/folder/function.php?variable=value&boolean=true">www.example2.com/folder</a>
I would like it to result in:
<a href="http://www.example1.com">www.example1.com</a>
<a href="http://www.example2.com/folder/function.php?variable=value&boolean=true">www.example2.c....oolean=true</a>
Anyone has an idea of how this could be done?
PS. I’m a noob when it comes to regular expressions

Hello,
You could use preg_replace_callback function - http://php.net/manual/en/function.preg-replace-callback.php . It allows you to use any formatting you want constructed from elements matched by pattern.
I’ve played with code below - it provides good result for your example. shortenUrl() is function from your post, shortenUrlNew() is new function.
function shortenUrl($textOriginal)
{
$urlPattern = "/(https?:\/\/)?(www.)?([-a-z0-9]*[a-z0-9]\.)(\bcom\b|\bbiz\b|\bgov\b|\bmil\b|\bnet\b|\borg\ b|[a-z][a-z]\.[a-z][a-z])\/?([a-zA-Z0-9]*)?([a-zA-Z0-9\.\?=\/&]*)?/";
$textNew = preg_replace($urlPattern, "<a href=\"$1$2$3$4/$5$6\" >$2$3$4/$5</a>", $textOriginal);
return $textNew;
}
function shortenUrlNew($textOriginal)
{
$urlPattern = "/(https?:\/\/)?(www.)?([-a-z0-9]*[a-z0-9]\.)(\bcom\b|\bbiz\b|\bgov\b|\bmil\b|\bnet\b|\borg\ b|[a-z][a-z]\.[a-z][a-z])\/?([a-zA-Z0-9]*)?([a-zA-Z0-9\.\?=\/&]*)?/";
$textNew = preg_replace_callback($urlPattern, "replaceLinkParts", $textOriginal);
return $textNew;
}
function replaceLinkParts($matches)
{
$howMuchSymbolsShouldBeLeft = 11;
return
'<a href="' . $matches[1]. $matches[2] . $matches[3] . $matches[4] . '/' . $matches[5] . $matches[6] . '">
' . $matches[2] . $matches[3] . substr($matches[4], 0, 1) . '....' .
substr($matches[6], (strlen($matches[6]) - $howMuchSymbolsShouldBeLeft), $howMuchSymbolsShouldBeLeft).
'</a>';
}
echo shortenUrl('http://www.example2.com/folder/function.php?variable=value&boolean=true');
echo '
<br><br>
';
echo shortenUrlNew('http://www.example2.com/folder/function.php?variable=value&boolean=true');
If you have any questions, don’t hesitate to ask.

Try something like this:
function shortenUrlNew($textOriginal)
{
$urlPattern = "/(https?:\/\/)?(www.)?([-a-z0-9]*[a-z0-9]\.)(\bcom\b|\bbiz\b|\bgov\b|\bmil\b|\bnet\b|\borg\ b|[a-z][a-z]\.[a-z][a-z])\/?([a-zA-Z0-9]*)?([a-zA-Z0-9\.\?=\/&-_]*)?/";
$textNew = preg_replace_callback($urlPattern, "replaceLinkParts", $textOriginal);
return $textNew;
}
function replaceLinkParts($matches)
{
$howMuchSymbolsShouldBeLeft = 15;
return
'<a href="' . $matches[1]. $matches[2] . $matches[3] . $matches[4] . '/' . $matches[5] . $matches[6] . '">
' . $matches[2] . $matches[3] . substr($matches[4], 0, 1) . '....' .
substr($matches[6], (strlen($matches[6]) - $howMuchSymbolsShouldBeLeft), $howMuchSymbolsShouldBeLeft).
'</a>';
}
echo shortenUrlNew('http://www.yiiframework.com/forum/index.php/topic/38181-shorten-urls-in-blog-using-preg-replace/page__p__183810');
