How to fix Drush 8 / PHP 7.2 Warning "count(): Parameter must be an array..."

Question

I am running LAMP on Ubuntu 16.04. I have a drupal 7 installation and I have installed drush 8.1.3 via Composer version 1.5.2. I believe there is bug in php7.2 causing the error as discussed on Github, however even after I applied the recommended fix which is to update the pear/console_table to the latest version instructed here, the problem still remains. I also followed the instructions on Super User to be absolutely sure that I have the most up to date version of pear installed as well (did not install PHPunit). And, FYI in accordance with the drush installation documentation found here, I also made the proper changes to my .bashrc file as well (below).

Whenever I run drush status I receive the following error:

count(): Parameter must be an array or an object that implements     [warning]
Countable Table.php:789

The contents of my ~/.bashrc file, are as follows:

export PATH="$HOME/.composer/vendor/bin:$PATH"

export PATH=/bin:/usr/local/bin:/usr/local/mysql/bin:$PATH

# Include Drush bash customizations.
if [ -f "/home/webdevusr/.drush/drush.bashrc" ] ; then
source /home/webdevusr/.drush/drush.bashrc
fi

# Include Drush completion.

if [ -f "/home/webdevusr/.drush/drush.complete.sh" ] ; then
source /home/webdevusr/.drush/drush.complete.sh
fi

# Include Drush prompt customizations.

if [ -f "/home/webdevusr/.drush/drush.prompt.sh" ] ; then
source /home/webdevusr/.drush/drush.prompt.sh
fi

The result of drush cc all executed from within my drupal installation folder is:

No Drupal site found, only 'drush' cache was cleared.

Anyone know how to get drush to working for my local (LAMP) Drupal 7 installations?

In the file .config/composer/vendor/pear/console_table/Table.php, we can see that the involved function _updateRowsCols($rowdata = null) has a wrong signature, its argument being assigned null as default - not countable.

Rather than using the @ operator as it could mute more error/warning than intended, it is preferable to fix the function signature :

function _updateRowsCols($rowdata = []) {...}

... and/or to use the Null Coalescing Operator ?? to safely fallback to an empty (but countable) array right in the function call :

$this->_max_cols = max($this->_max_cols, count($rowdata ?? []));

[Edit] It's worth noting that the fix for this issue was committed to pear/Console_Table in October 2017 while the question was asked on 2018.. so just use the latest version... Anyway, just for information here is the code fix which use a ternary operator probably for backward compatibility :

function _updateRowsCols($rowdata = null)
    {
        // Update maximum columns.
        $this->_max_cols = max($this->_max_cols, is_array($rowdata) ? count($rowdata) : 0);

        ...
    }

You can edit .config/composer/vendor/pear/console_table/Table.php or look for that file first in your system. Open it with your favorite editor and in edit line 789. Silence it like this:

@$this->_max_cols = max($this->_max_cols, count($rowdata));

You're good to go.
