Fatal error: Class 'IntlDateFormatter' not found
问题 I installed WAMP on my local machine. My PHP version is 5.3.3 in phpinfo() but that extension doesn't exist! :( How can I install this extension without compiling it? Here is just source of it. 回答1: The extension was there! All you need to do is clearing the comment(;) before this line in php.ini file: ;extension=php_intl.dll to extension=php_intl.dll 回答2: if you see this on Debian / other Linux platforms. sudo apt-get install php5-intl - for PHP 5.6 sudo apt-get install php7.0-intl - PHP 7+
