How to enable Xdebug for MacOS Big Sur? "php -m" show its ok, but "phpinfo();" don't

I just updated my MacOS to Big Sur and my localhost configuration was a mess. After reinstalling PHP and Xdebug, it seems my Xdebug is not working properly. I can see it is installed through php -m, but it is not listed in phpinfo();. Also, If I open a VSCode, start "Listen for XDebug", add a breakpoint to a file and run php -e FILENAME.php, the breakpoint works, but if I do the same using a browser, is doesn't.

Already tried the official tutorial that used homebrew and several other tutorials, since from installing it manually until doing all stuff automated. I'm out of clues here, any help or ideas are welcome. Thanks in advance.

Below follows my config:

  • PHP: 7.4.10
  • Xdebug config in php.ini
[xdebug]
zend_extension="/usr/local/Cellar/php/7.4.10/lib/php/20190902/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.remote_host=localhost
xdebug.remote_handler=dbgp
xdebug.remote_port=9000
  • VSCode launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000,
            "xdebugSettings": {
                "max_data": -1
            }
        }
    ]
}

When I had this issue after upgrading to big sur, it was caused by :

Failed loading /usr/local/lib/php/pecl/20200930/xdebug.so: dlopen(/usr/local/lib/php/pecl/20200930/xdebug.so, 9): no suitable image found. Did find: /usr/local/lib/php/pecl/20200930/xdebug.so: code signature in (/usr/local/lib/php/pecl/20200930/xdebug.so) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

After trying to create/find a signed xdebug.so or to turn off signing verification on my mac for far too long I eventually solved the issue by installing a new httpd with brew.

Here is what I did to make xdebug work under Big Sur

There are two signed files located in /usr/lib/php/extensions/no-debug-non-zts-20180731 - xdebug.so and opcache.so but they will not work with PHP greater than 7.3

If you can downgrade to 7.3 then

  1. Use brew to install php 7.3: brew install php@7.3
  2. Update httpd.conf according to brew instructions
  3. Switch to 7.3 if you under different version: brew unlink php && brew link --force --overwrite php@7.3
  4. Add this section at the end of 7.3 php.ini:
    [xdebug]
    zend_extension = "/usr/lib/php/extensions/no-debug-non-zts-20180731/xdebug.so"
    xdebug.remote_enable = 1
    xdebug.remote_autostart = 1

  1. Restart Apache server

  2. Check is Xdebug is enabled: php -i | grep "xdebug support"
