Create columns in PHP [duplicate]

Transposing multidimensional arrays in PHP (13 answers)

Closed 10 months ago.

I have some values in array like this:

$elm = 'a,b,c';
$elm2 = 'd,e,f';

I would like to create a table out of this data which would look like this:

table:
a d
b e
c f

It seems impossible, since HTML tables are created horizontally, I'm always somehow getting this:

table:
a b c
d e f 

I tried many things for instance:

echo '<table>';

 foreach($html->find($elm) as $m){
   echo '<tr><td>' . $m . '</td>'; 

 foreach($html->find($elm2) as $m2){
        echo '<td>' . $m2 . '</td>';
    }

echo '</tr>';
}

echo '</table>';

Which gives me this:

table:
a d e f
b d e f
c d e f 

So the first column is correct but the other ones are spread out horizontally and duplicated.

Answer 1

Some magic:

$array = [explode(',',$elm), explode(',',$elm2)];
$array = call_user_func_array('array_map', array_merge([NULL], $array));

foreach ($array as $sub) {
    echo implode(' ', $sub) . "\n";
}

Output:

a d
b e
c f

Answer 2

Try -

$elm = 'a,b,c';
$elm2 = 'd,e,f';

$explode1 = explode(',', $elm);
$explode2 = explode(',', $elm2);    

echo "<table>";

for($i=0; $i<sizeof($explode1); $i++)
{
    echo "<tr>";
       echo "<td>".$explode1[$i]."</td>";
       echo "<td>".$explode2[$i]."</td>";
    echo "</tr>";
}

echo "</table>";

OUTPUT

<table>
    <tr>
       <td>a</td>
       <td>d</td>
    </tr>
    <tr>
       <td>b</td>
       <td>e</td>
    </tr>
    <tr>
       <td>c</td>
       <td>f</td>
    </tr>
</table>

Are we playing golf?

foreach(array_combine(explode(',', $elm), explode(',', $elm2)) as $k => $v){
  echo "$k $v\n";
}
