I have just updated to PHP7 via Homebrew. I now get the following error message when doing a php -v:

PHP Deprecated:  PHP Startup: memcached.sess_lock_wait and memcached.sess_lock_max_wait are deprecated. Please update your configuration to use memcached.sess_lock_wait_min, memcached.sess_lock_wait_max and memcached.sess_lock_retries in Unknown on line 0

Can anyone suggest where I'm going wrong?

I have the following packages listed and installed via Homebrew.

memcached php56-memcached php70-memcached

Thanks.

    I suppose you should uninstall the older memcached packages. Maybe [this](http://stackoverflow.com/questions/11966640/uninstall-memcached-and-or-force-install-with-homebrew-mac-os-x) could help to do that. – trincot Feb 01 '16 at 12:43

I had to comment out the following entries in /usr/local/etc/php/7.0/conf.d/ext-memcached.ini.

;memcached.sess_lock_wait = 150000
;memcached.sess_lock_max_wait = 0;

The numbers are in microseconds (see http://php.net/manual/en/memcached.configuration.php)

The new settings in PHP 7.0+ are:

; The minimum time, in milliseconds, to wait between session lock attempts.
; This value is double on each lock retry until memcached.sess_lock_wait_max
; is reached, after which any further retries will take sess_lock_wait_max seconds.
; Default is 1000.

memcached.sess_lock_wait_min = 1000;

; The maximum time, in milliseconds, to wait between session lock attempts.
; Default is 2000.

memcached.sess_lock_wait_max = 2000;

; The number of times to retry locking the session lock, not including
; the first attempt.
; Default is 5.

memcached.sess_lock_retries = 5;

    Don't forget to replace these rather than just remove them. The warning says: `Please update your configuration to use memcached.sess_lock_wait_min, memcached.sess_lock_wait_max and memcached.sess_lock_retries in Unknown on line 0` – Oliver Tappin Aug 14 '16 at 15:06

The memcached.sess_lock_wait and memcached.sess_lock_max_wait values have been replaced by memcached.sess_lock_wait_min and memcached.sess_lock_wait_max (note "max" is now at the end of the variable name). Change these variable names and set to 0 (for default) or other values as desired. If using defaults, simply commenting out the declarations does the trick.

Same issue here. But as far as I know there is no stable release yet. See: https://github.com/php-memcached-dev/php-memcached/issues/213#issuecomment-178613213
