Fedora 20 is from 2013 which means 8 years which means you are an idiot given that you for sure not
capable to compile *everything* at your own
your gcc, glibc and other low level stuff are a joke in 2021

Hmm, you didn't tell me that is was a c function. Just from looking at the name I can't
determine that. Anyway, we got the proper output from phpinfo().
I haven't found it in LD_LIBRARY_PATH. I'm running Fedora 20 and haven't updated any
yum packages for more than 4 years, because I compile everything myself anyway. And I do know that I
haven't installed nor compilled 1.1.3 ever.
I really have no idea where this should be coming from. I'll try to replace the config.m4 with
the one from 7.3. Let's see if that works.

zlibVersion() is a C function. :)
> The output from pkgconfig looks ok:
Yes. However, I assume that the old zlib version is somewhere in
your LD_LIBRARY_PATH, or so. Sorry, I'm usually working on
Windows, so I can't help any further, but I don't think this is a
PHP bug.

Hmmm, still not working, but we got the output from phpinfo anyway.
php > echo zlibVersion();
PHP Warning: Uncaught Error: Call to undefined function zlibVersion() in php shell code:1
The output from pkgconfig looks ok:
# pkg-config --print-provides zlib
zlib = 1.2.8

Oh indeed, the proper spelling is zlibVersion(), and that function
is used to retrieve the linked version[1]. To my knowlege, PHP does
not (and never did) bundle zlib, so this old version must be somewhere
on your system. I assume that the difference between PHP 7.3 and 7.4
is due to build system changes; 7.4 uses pkg-config to detect zlib[2]
while 7.3 manually searched for the lib in the usual places[3].
Anyhow, what does
pkg-config --print-provides zlib
report?

zlib_version() tells me undefined function in the php shell. But:
php > echo ZLIB_VERSION;
1.2.8
But then I looked at the phpinfo() output and found something very strange:
ZLib Support => enabled
Stream Wrapper => compress.zlib://
Stream Filter => zlib.inflate, zlib.deflate
Compiled Version => 1.2.8
Linked Version => 1.1.3
My zlib version on the system is 1.2.8. There is nowhere a 1.1.3 in any of my lib directories.
And on PHP 7.3 both match and say 1.2.8.
I can assure you that there is no 1.1.3 of zlib on my system and I have no idea where this is coming
from. ldd for my php 7.4 binary shows:
libz.so.1 => /usr/lib64/libz.so.1 (0x00000036d3200000)
and ls -la /usr/lib64/libz.so.1 shows: /usr/lib64/libz.so.1 -> libz.so.1.2.8
I just compiled 7.3 again and all works. I compile 7.4 and same problem. It's very puzzling,
since I certainly haven't installed libz 1.1.3, nor is it present in any of my lib paths. (Why
would I install an older version?) Also, in that case 7.3, would pick it up too.
We have a mystery on our hands.
The only logical explanation would be that PHP 7.4 bundles 1.1.3 and statically links it.
