Are you sure have installed opcache.so?
ls $(php-config --extension-dir)

Output of ls $(php-config --extension-dir)
opcache.so

dlopen failed: library "/data/data/com.termux/files/usr/lib/php/opcache.so.so" not found

It seems to be looking for opache.so.so now, maybe your php.ini should contain

zend_extension = opcache

instead of

zend_extension = opcache.so

?

Php finding libs with ".so" and without ".so", i think that is optional.
The problem goes here

PHP Warning: Failed loading Zend extension 'opcache.so' (tried: /data/data/com.termux/files/usr/lib/php/opcache.so (dlopen failed: cannot locate symbol "PHP_MD5Update" referenced by "/data/data/com.termux/files/usr/lib/php/opcache.so"...),

@Cvar1984 you are right, thanks.

So this is essentially the same issue as #2479 so I'll close this in favour of that one so that we are tracking this in a single issue. One workaround is to export LD_PRELOAD=$PREFIX/libexec/apache2/library-with-PHP_MD5Update.so before starting httpd.

I am using a termux-services script for httpd containing

#!/data/data/com.termux/files/usr/bin/sh
export LD_PRELOAD=$PREFIX/libexec/apache2/mod_proxy.so
exec httpd -f $HOME/apache2/httpd.conf -DNO_DETACH 2>&1

to workaround a similar issue.
