Deprecated: The each() function is deprecated в PHP 7.2

При переносе кода из PHP 5.4 на PHP 7.2 в libmail.php словил следующую ошибку:

Deprecated: The each() function is deprecated.

1	Deprecated: The each() function is deprecated.

Код:

while (list ($hdr, $value) = each($this->xheaders)) {

}

while (list ($hdr, $value) = each($this->xheaders)) {

...

}

foreach ($this->xheaders as $hdr=>$value){
}

1 2	foreach ($this->xheaders as $hdr=>$value){ }

while (list (, $line) = each($lines)) {

на

foreach ($lines as $line) {

1	foreach ($lines as $line) {
