The each function in Magento with PHP 7.2

[luigifab]

Hello world

I have created a "pseudo fix" for the deprecated each function used in Magento.
I'm working on it since 20 minutes, but now I can browse my Magento 1.4.1.0, 1.5.0.1, 1.6.0.0, 1.7.0.0, 1.8.0.0, 1.9.0.0, 1.9.0.0, 1.9.3.9 (frontend and backend) with PHP 7.2.9 (with the v3 of Inchoo/PHP7 module).

First, in all files where I found = each(, I used some regular expressions:

while \(list\s*\(\$([a-z0-9A-Z_]+), \$([a-z0-9A-Z_]+)\) = each\(\$([a-z0-9A-Z_\[\]']+)\)\)
foreach ($\3 as $\1 => $\2)

while \(list\s*\(,\s*\$([a-z0-9A-Z_]+)\) = each\(\$([a-z0-9A-Z_\[\]']+)\)\)
foreach ($\2 as $\1)

while \(list\s*\(\$([a-z0-9A-Z_]+),\s*\) = each\(\$([a-z0-9A-Z_\[\]']+)\)\)
foreach ($\2 as $\1 => $abcdefg)

 list\s*\(\$([a-z0-9A-Z_]+), \$([a-z0-9A-Z_]+)\) = each\(\$([a-z0-9A-Z_\[\]']+)\);
 foreach ($\3 as $\1 => $\2) { break; }

Secondly, I make some manual change.
