The described situation sounds barely as a PHP issue. With the given ICU configuration, any chroot'ing program would have an issue. PHP is also available with other SAPIs like Apache module, etc. that don't require chroot'ing. The suggestion to extra mount data directory is plausible. The check for an erroneous function output needs to be done in the application, adding a check in a single function for an unusual use case is IMO an overkill. Changing the type to the documentation issue therefore.

@shalom at starltd dot net, your issue seems to be ICU data and version dependent and thus not related to this ticket.

Thanks

Hello
also for php7.1.13
I try to use:
echo idn_to_ascii('täst.de'); 
and it's work and show: xn--tst-qla.de
but, when I try to use:
echo idn_to_ascii('בדיקה123.co.il'); 

it's show empty blank page, no error and no value

Regards

But I agree with "If idn_to_ascii() is empty, show or save in errorlog some E_NOTICE or similar"
It's too hard to find the problematic function without any error/notice messages.

/usr/local/share/icu should be mounted into chrooted environment to make idn_to_ascii() working
