Different results for json_encode in Wordpress with php compiled with same configuration and libmbfl version

  • 772

I have an older Debian server and a local install of Wordpress; I'm trying to track down why calling:

echo json_encode('?');

on the Debian server results in "\ud83dde00" but on my local install, calling the same json_encode line results in "\ud83d\ude00" (which is what I'd expect to see on the Debian server too)...

Both versions of php are compiled with mbstring=all enabled, and both use libmbfl version 1.3.2

    Facepalm. Because I had --disable-all the json module wasn't being compiled in, so adding --enable-json and recompiling then means that echo json_encode('?'); now returns "\ud83d\ude00"
