PHP Fatal error: Uncaught Error: Call to undefined function idn_to_ascii() on PHP 7.2.13

I'm trying to use idn_to_ascii() on PHP version 7.2.13 but I'm receiving:

Uncaught Error: Call to undefined function idn_to_ascii()

I don't have the PECL intl extension installed, but according to the top user contributed note on the documentation, I don't need it:

"...if you have >=5.4 you will not require the PECL extensions. "

Is the user note wrong? If not, then what am I doing wrong?

Solution

  • You probably need to activate the "intl" php module.

    You can do it by cPanel Select PHP Version configuration by checking the "intl" module and save.
