Unable to display the exact HTML code with PHP for loop - php

Question

for ($i = 0; $i < count($item); $i++) {
echo '<ul class="list1">';
if ($i <= 1) {
echo '<li>'.$item[$i].'</li>';
}
echo '</ul>';
echo '<ul class="list2">';
if ($i >= 2 && $i <= 7) {
echo '<li>'.$item[$i].'</li>';
}
echo '</ul>';
}
I tried to display the following HTML with only php(above code) however, it seems like it's not working as expected. How can I display the exact same thing with php?
<ul class="list1">
<li>
<? echo $item[0];?>
</li>
<li>
<? echo $item[1];?>
</li>
</ul>
<ul class="list2">
<li>
<? echo $item[2];?>
</li>
<li>
<? echo $item[3];?>
</li>
<li>
<? echo $item[4];?>
</li>
<li>
<? echo $item[5];?>
</li>
<li>
<? echo $item[6];?>
</li>
<li>
<? echo $item[7];?>
</li>
</ul>

Answer 1

do something like this,
<?php
$item = ['1','2','3','4','5','6','7','8'];
for ($i = 0; $i < count($item); $i++) {
if ($i < 1) {
echo '<ul class="list1">';
}
if ($i <= 1) {
echo '<li>'.$item[$i].'</li>';
}
if ($i == 1) {
echo '</ul>';
}
if ($i == 2) {
echo '<ul class="list2">';
}
if ($i >= 2 && $i <= 7) {
echo '<li>'.$item[$i].'</li>';
}
if ($i == 7) {
echo '</ul>';
}
}
?>

Answer 2

this is the simplified syntax for the expected output
echo '<ul class="list1">';
for ($i = 0; $i < count($item); $i++) {
echo '<li>'.$item[$i].'</li>';
if ($i == 1) {
echo '</ul><ul class="list2">'';
}
}
echo '</ul>';

Answer 3

Try use two for loop, first loop items from 0 to 1 in "list1", second loop items form 2 to 7 in "list 2"
echo '<ul class="list1">'
for ($i = 0; $i <= 1; $i++) {
echo '<li>'.$item[$i].'</li>'
}
echo '</ul>';
echo '<ul class="list2">'
for ($i = 2; $i <= 7; $i++) {
echo '<li>'.$item[$i].'</li>'
}
echo '</ul>';
