To finish installing blackfire for PHP 5.6:

* /usr/local/etc/php/5.6/conf.d/ext-blackfire.ini was created,

* Validate installation via one of the following methods:

  Using PHP from a webserver:

  - Restart your webserver or PHP-fpm.
  - Write a PHP page that calls "phpinfo();"
  - Load it in a browser and look for the info on the "blackfire" module.
  - If you see it, you have been successful!

  Using PHP from the command line:

  - Run php --ri blackfire
  - If the "blackfire" configuration is displayed, you have been successful!

Dear @kix , how have you installed the blackfire extension?

It seems you're using a ZTS extension with a non-ZTS PHP, or opposite.

[kix]

@romainneutron: trying blackfire from Homebrew against PHP 5.6 --with-thread-safety, let's see where this leads me. Also, inspecting brew options blackfire-php56, I don't see a way to choose whether I want a thread safe or non-safe extension, so there's no way to know which version I have installed.

[romainneutron]

I now understand the issue. The Homebrew formula does not detect thread safety correctly. Please brew uninstall --force blackfire-php56 and install the appropriate extension manually using the "Manual" tab at this page https://blackfire.io/docs/up-and-running/installation#installation-instructions

[romainneutron]

My bad @kix, I forgot this : you can use blackfire homebrew tap to install. Forget the manual install, just:

brew uninstall --force blackfire-php56
brew install  blackfire-php56-zts

[kix]

@romainneutron, thanks, the last suggestion worked as a charm!

[f3l1x]

I've had some problem, using PHP 7.2. Solved by installing blackfire NON-ZTS.

[d8vjork]

PHP 8.1 having the same problem here.

I don't have PHP with thread safety, but still have this problem, tried thousand things but no luck
