PHP Tidy class not found, error
htmltidy, php, php-ini, tidy
Solution
Your php.ini contains a list of "extension=somefile.so" lines. You are missing the correct line for your tidy extension. It should be included but commented in your file. Just remove the ; character in front of the one line for the tidy extension and restart your webserver.
Sample for windows:
extension=php_tidy.dll
Sample for Linux:
extension=tidy.so
On some Linux distribution, it has to be installed if you can't find the extension file `tidy.so` in your extensions folder. Execute the correct line depending on your distribution. You have to be root or use sudo:
CentOS/RedHat (replace with correct lib as found via `yum search php-tidy`:
yum install rh-php56-php-tidy.x86_64
Debian/Ubuntu:
apt-get install php5-tidy
Problem
I was writing some code for repair html string. I read some nice solutions which work with the Tidy PHP class but I had some troubles with it. What in this post is written, is exactly what I want but I need to install / load the PHP Tidy class. Close tags from a truncated HTML string I'm working on `PHP 5.5.4`. I tried to install tidy following some tutorials but nothing has append. When I call the tidy class `$tidi = new \tidy();`, NetBeans suggests me the class and clicking on it (Ctrl + click) I see it but refreshing the page I obtain the error `Class 'tidy' not found in ... /myfile.php line ...` I used in the same way the class `$myVar = new \DomDocument();` but it works perfectly. Checking whether the Tidy extension is loaded like below, I get "NOT LOADED". ``` echo extension_loaded('tidy') ? "LOADED" : "NOT LOADED"; ``` Please, can someone explain me how Tidy works and how can I set it up? My Ubuntu's version is 13.10.
