Internal Link Building not working in PHP8? [The solution]

The Internal Link Plugin breaks when updating to PHP 8, and here is the fix I made (using ChatGPT):

You have to edit the file: internal_link_building.php

You’ll find it here:

/wp-content/plugins/internal-link-building-plugin/internal_link_building.php

Line 454 find this:

while (list($name, $ops) = each($keywords)) {

				if($name == 'keywords_time')
					continue;

				$case = '';
				if($ops['case'] == 1)
					$case = ' checked="checked" ';
				$nofollow = '';
				if($ops['nofollow'] == 1)
					$nofollow = ' checked="checked" ';
				$newwindow = '';
				if($ops['newwindow'] == 1)
					$newwindow = ' checked="checked" ';

				$name = str_replace("'","'",stripslashes($name));

				echo "
					<tr>
						<td><input type='text' style='width:90%;' value='$name' name='internal_link_building[$x][name]' /></td>
						<td><input type='text' style='width:90%;' value='$ops[url]' name='internal_link_building[$x][url]' /></td>
						<td><input type='text' value='$ops[times]' name='internal_link_building[$x][times]' size='4' /></td>
						<td><input type='text' value='$ops[between]' name='internal_link_building[$x][between]' size='4' /></td>
						<td><input type='text' value='$ops[before]' name='internal_link_building[$x][before]' size='4' /></td>
						<td><input type='text' value='$ops[after]' name='internal_link_building[$x][after]' size='4' /></td>
						<td><input type='checkbox' $case value='1' name='internal_link_building[$x][case]' /></td>
						<td><input type='checkbox' $nofollow value='1' name='internal_link_building[$x][nofollow]' /></td>
						<td><input type='checkbox' $newwindow value='1' name='internal_link_building[$x][newwindow]' /></td>
					</tr>
					";
				$x++;
			}

Replace that code with this:

foreach ($keywords as $name => $ops) {

    if($name == 'keywords_time')
        continue;

    $case = '';
    if($ops['case'] == 1)
        $case = ' checked="checked" ';
    $nofollow = '';
    if($ops['nofollow'] == 1)
        $nofollow = ' checked="checked" ';
    $newwindow = '';
    if($ops['newwindow'] == 1)
        $newwindow = ' checked="checked" ';

    $name = str_replace("'","'",stripslashes($name));

    echo "
        <tr>
            <td><input type='text' style='width:90%;' value='$name' name='internal_link_building[$x][name]' /></td>
            <td><input type='text' style='width:90%;' value='{$ops['url']}' name='internal_link_building[$x][url]' /></td>
            <td><input type='text' value='{$ops['times']}' name='internal_link_building[$x][times]' size='4' /></td>
            <td><input type='text' value='{$ops['between']}' name='internal_link_building[$x][between]' size='4' /></td>
            <td><input type='text' value='{$ops['before']}' name='internal_link_building[$x][before]' size='4' /></td>
            <td><input type='text' value='{$ops['after']}' name='internal_link_building[$x][after]' size='4' /></td>
            <td><input type='checkbox' $case value='1' name='internal_link_building[$x][case]' /></td>
            <td><input type='checkbox' $nofollow value='1' name='internal_link_building[$x][nofollow]' /></td>
            <td><input type='checkbox' $newwindow value='1' name='internal_link_building[$x][newwindow]' /></td>
        </tr>
        ";
    $x++;
}

Then save. And it should work again ??
