Change code with 2 for loop in PHP - php

Question

I tried many hours to simplify this code:
<?
echo '<div class="eme3-left">'."\n".'<table>'."\n";
for ($n=1,$i=10; $n<=100,$i<=100;$n+=10,$i+=10)
{
echo '<tr>
<td class="dick-grau">'.$n.' → '.$i.'</td>
<td>'.$n.' = '.decbin($n).'<sub>2</sub></td>
<td>'.($n+1).' = '.decbin($n+1).'<sub>2</sub></td>
<td>'.($n+2).' = '.decbin($n+2).'<sub>2</sub></td>
<td>'.($n+3).' = '.decbin($n+3).'<sub>2</sub></td>
<td>'.($n+4).' = '.decbin($n+4).'<sub>2</sub></td>
<td>'.($n+5).' = '.decbin($n+5).'<sub>2</sub></td>
<td>'.($n+6).' = '.decbin($n+6).'<sub>2</sub></td>
<td>'.($n+7).' = '.decbin($n+7).'<sub>2</sub></td>
<td>'.($n+8).' = '.decbin($n+8).'<sub>2</sub></td>
<td>'.($n+9).' = '.decbin($n+9).'<sub>2</sub></td>';
};
echo '</tr></table>'."\n".'</div>';
?>
How to add the if condition from the third code for the second for loop ?
<?php
echo '<div class="eme3-left">'."\n".'<table>'."\n";
for ($n=1,$i=10; $n<=100,$i<=100; $n+=10, $i+=10) {
echo '<TR>'."\n".'<td class="dick-grau">'.$n.' → '.$i.'</td>';
for ($t = 1; $t<=10; $t++) {
echo '<td>'.$t.' = '.decbin($t).'<sub>2</sub></td>'."\n";
}
echo "</tr>";
}
echo '</table>'."\n".'</div>';
?>
In another version the following loop works perfectly, but when I add it to the code above, the if-condition don't work.
for($i=1;$i<=100;$i++){
echo '<td>'.$i.' = '.decbin($i).'<sub>2</sub></td>'."\n";
if($i%10 == 0)
echo '</tr>'."\n";
}
Maybe their are more suggestions for improvements.

Answer 1

This is not a complete example but should get you there.
<?php
$ints = range(1,100);
$ints_grouped_by_10 = array_chunk($ints,10);
foreach($ints_grouped_by_10 as $int_group){
echo "<tr>";
echo '<td class="dick-grau">'.reset($int_group).' → '.end($int_group).'</td>';
foreach($int_group as $int){
echo "<td>{$int} = ".decbin($int)."</td>";
}
echo "</tr>";
}
?>
[Edit] added the legend (1 -> 10, 11 -> 20)

Answer 2

echo '<div class="eme3-left">'."\n".'<table>'."\n";
for ( $n=1 ; $n <= 100 ; $n+=10 )
{
echo '<tr>
<td class="dick-grau">'.$n.' → '.($n+9).'</td>';
for ( $j = 0 ; $j < 10 ; $j++ )
echo '<td>'.($n + $j).' = '.decbin($n+$j).'<sub>2</sub></td>';
echo '<tr>';
}
echo '</table>'."\n".'</div>';
