Mcrypt module is installed, but missing in phpinfo

[ikurnosov]

Hi, currently trying to setup a project using PHP 7.4 on macOS Big Sur. The project requires mcrypt library.
So I followed all the instructions and set up PHP 7.4.27:

brew install shivammathur/php/php@7.4
echo 'export PATH="/usr/local/opt/php@7.4/bin:$PATH"' >> /Users/test/.bash_profile
echo 'export PATH="/usr/local/opt/php@7.4/sbin:$PATH"' >> /Users/test/.bash_profile
export LDFLAGS="-L/usr/local/opt/php@7.4/lib"
export CPPFLAGS="-I/usr/local/opt/php@7.4/include"
brew link --overwrite --force shivammathur/php/php@7.4

Thereafter installed mcrypt:

brew install mcrypt
/usr/local/opt/php\@7.4/bin/pecl install mcrypt-1.0.4
pecl config-get ext_dir | pbcopy
mkdir -p /usr/local/lib/php/pecl/20190902
/usr/local/opt/php\@7.4/bin/pecl install mcrypt-1.0.4

Created conf.d/mcrypt.ini:

[mcrypt]
extension="/usr/local/opt/php@7.4/lib/php/20190902/mcrypt.so"

Restarted Apache, however phpinfo() shows all info from php.ini correctly except missing mcrypt module.
At the same time, CLI shows different result:

$ php -i | grep mcrypt
/usr/local/etc/php/7.4/conf.d/mcrypt.ini
Registered Stream Filters => zlib.*, bzip2.*, convert.iconv.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

$ php -m | grep mcrypt
mcrypt

Checked CLI ini:

$ php --ini
Configuration File (php.ini) Path: /usr/local/etc/php/7.4
Loaded Configuration File:         /usr/local/etc/php/7.4/php.ini
Scan for additional .ini files in: /usr/local/etc/php/7.4/conf.d
Additional .ini files parsed:      /usr/local/etc/php/7.4/conf.d/ext-opcache.ini,
/usr/local/etc/php/7.4/conf.d/mcrypt.ini

It is the same as in phpinfo():

I'm stuck 😢 Any help would be appreciated.
Could there be any issue due to built-in extensions and use pkg config?

UPD: extension_dir = "/usr/local/Cellar/php@7.4/7.4.27/pecl/20190902" Changing the extension_dir didn't help as well.

As per your output of php -i | grep mcrypt, It seems to be installed correctly. In phpinfo() you should have a mcrypt heading.

[ikurnosov]

Btw, which version of PHP do you use?

[shivammathur]

I used the same shivammathur/php/php@7.4, but could not reproduce the issue.

[ikurnosov]

Is there any reasons for phpinfo() to ignore modules? Like apache caching modules set or whatever..
Do you use Apache or anything else?
How did you install mcrypt module?

[shivammathur]

I used Apache using brew package httpd.

[ikurnosov]

Unfortunately, I don't.

Also, I've checked CLI with explicit INI file set:

$ php -c /usr/local/etc/php/7.4/php.ini -i | grep mcrypt
Registered Stream Filters => zlib.*, bzip2.*, convert.iconv.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

But it still doesn't appear on phpinfo() webpage.

[shivammathur]

Did you restart php-fpm and httpd after installing mcrypt using pecl.
If not, please do this and check phpinfo() again

brew services restart php@7.4
brew services restart httpd

[ikurnosov]

Yes, many times. I'm using built-in apache, so I did it with sudo apachectl -k restart, also tried sudo apachectl -k graceful.
Even rebooted my machine several times.

[shivammathur]

Try using the brew httpd instead of system one.

[ikurnosov]

Thanks a lot! Brew's httpd fixed the issue, now I can use mcrypt.

So, my guess is there is kind of caching modules within built-in apache.
