The log also shows you are using the Xcode command line tools version 15.3. This problem is caused by using Xcode or CLT version 15.3 or later because those versions consider implicit int to be an error. Previous compilers allowed implicit int with just a warning. For reasons of laziness we still use Xcode and CLT 15.2 on our macOS 14 build machines and this is able to build PHP without problems.
PHP cleaned up its code for implicit int issues in version 8.0, for example in this commit. I need to either backport that commit, and probably others, or downgrade the error back to a warning to allow php74 and earlier to build again with the latest Xcode and CLT.
If you are able to use a newer version of PHP for your project, try php80 or newer. They shouldn't have this problem.
If you require php74 or older, with the understanding that those versions have reached end of life, you can work around the problem by running:
sudo port clean php74-apache2handler
sudo port install php74-apache2handler configure.cflags="-Os -Wno-error=implicit-int"
