To enable intl extension follow the instructions below.

You need enable extension by uncommenting the following line extension=php_intl.dll in the C:\xampp\php\php.ini file. Once you uncomment the extension=php_intl.dll, then you must restart apache server using XAMPP control panel.

//about line 998
;extension=php_intl.dll 
change as
extension=php_intl.dll

(Note: php.ini file mostly in the following directory C:\xampp\php)

Restart xampp

PHP uses a different php ini for command line php than for the web apache php  So you see the intl extension in phpinfo   in the browser  but if you run php -m in the command line you might see that the list of extensions there does not include intl  You can check using php -i on top of the output it should tell you where the ini file is loaded from  Make sure you enable the intl extension in that ini file and you should be good to go  For php ini 5 6 version  check version using php -v   extension php intl dll    remove semicolon extension php intl dll  For php ini 7   version  extension intl   remove semicolon extension intl

If You have got this error while running composer install command  don t worry  Steps to be followed and requirements    Step1  Go to server folder such as xampp or  wampp etc  Step2  open php folder inside that and go to ext folder  Step3  If you find a file named as php intl dll no problem    Just go to php ini file and uncomment the line  From    extension php intl dll   To   extension php intl dll    Step4  restart xampp  thats it   Note  If you don t find any of the file named as php intl dll  then you need to upgrade the PHP version

For php ini 5 6 version  check version using php -v    extension php intl dll    remove semicolon and keep like this extension php intl dll  For php ini 7   version   extension intl   remove semicolon and keep like this extension intl  Note - After That Make Sure to Restart Your Xampp Wamp Server in you Local Machine

just remove them    ext-intl          from your composer json file   Because sometimes for some helper functions  the IDE complains that the extension is missing from the composer json file  Immediately press Alt Enter to add it to the composer  But that doesn t mean that composer will count them in  The composer will complain next time while doing some operations  So that  we should not blindly type Alt Enter rather than installing them manually in composer by doing composer install  lt package-name gt    As I think you have entered it manually  you should remove it  then install it in proper procedure composer install  lt package-name gt   Or else you can run composer update to count that added dependencies in
