libldap-2.4.2.dylib not loaded after switch php version – PHP Versions

I get this error dyld: Library not loaded: /usr/local/opt/openldap/lib/libldap-2.4.2.dylib when switch php verison back to 8.0.

I can fix it by brew reinstall [email protected], but it will happend again when switch verison.

I am using MacOS Big Sur 11.4, but Mojave also got this problem.

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/[email protected]/lib/httpd/modules/libphp7.so

    <FilesMatch .php$>
        SetHandler application/x-httpd-php

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.4/

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.


To have launchd start [email protected] now and restart at login:
  brew services start [email protected]
Or, if you don't want/need a background service you can just run:
  php-fpm

Required: [email protected] ✔
==> Caveats
openldap is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have openldap first in your PATH, run:
  echo 'export PATH="/usr/local/opt/openldap/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/openldap/sbin:$PATH"' >> ~/.zshrc

For compilers to find openldap you may need to set:
  export LDFLAGS="-L/usr/local/opt/openldap/lib"
  export CPPFLAGS="-I/usr/local/opt/openldap/include"

For pkg-config to find openldap you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openldap/lib/pkgconfig"
