Variable substitution in a cell?

Question

PHP

I have php code

<?php
# Путь к файлу
$file_name = "set.txt";

# Считываем информацию по строкам
$data = file( $file_name );
$i = 1;


echo '<table border="1">';
echo	   ' <tr>
        <th>№</th>
        <th>Название</th>
        <th>Уровень</th>
        <th>Очки</th>
        <th>Очки</th>
        <th>Очки</th>
        <th>Очки</th>
        <th>Очки</th>
         <th>Очки</th>
        </tr>';


# В цикле обходим массив данных
foreach( $data as $value ):

# Разбиваем строку по |
$value = explode( "|", $value );

echo '<tr>';


{
echo '<td>' . $i++ . '</td>';
echo '<td>' . $value[0] . '</td>';
echo '<td>' . $value[1] . '</td>';
echo '<td>' . $value[2] . '</td>';
echo '<td>' . $value[3] . '</td>';
echo '<td>' . $value[4] . '</td>';
echo '<td>' . $value[5] . '</td>';
echo '<td>' . $value[6] . '</td>';
echo '<td>' . $value[7] . '</td>';
echo '</tr>';
}

endforeach;

echo '</table>';
?>

how can I insert the result of such an operation into a specific cell

<?php $host="192.168.1..1"; exec("ping -c 1 " . $host, $output, $result); if ($result == 0)       echo "<img src='/set/img/ok.png'  width='40' height='40'  >"; else echo "<img src='/set/img/no.png'  width='40' height='40' ";?>

It's just that the problem is that the table construction is taken from the data from the .txt file

Answer 1

$custom_data = '';
$host="192.168.1..1"; 
exec("ping -c 1 " . $host, $output, $result);
if ($result == 0) $custom_data =  "<img src='/set/img/ok.png'  width='40' height='40'  >"; else $custom_data = "<img src='/set/img/no.png'  width='40' height='40' ";

foreach( $data as $value ):

# Разбиваем строку по |
$value = explode( "|", $value );

echo '<tr>';


{
echo '<td>' . $i++ . '</td>';
echo '<td>' . $value[0] . '</td>';
echo '<td>' . $value[1] . '</td>';
echo '<td>' . $value[2] . '</td>';
if($i == 4 /* 4 строка*/) $value[3] = $custom_data;
echo '<td>' . $value[3] . '</td>';
