TABLES AND ARRAYS

[davo666]

hi,

i would like to put an array in a table,but heres the catch - the table has to be square! not just a list down the page

im think a foreach looop but any ideas are welcome

thanks in advance

Well, you could just use the foreach() to output a table then use CSS to format it. Ex:

print('<table style="width:300px; height:300px;">');

foreach ($rows as $row) {
    print('  <tr>');

foreach ($row as $col) {
    print('    <td>' . $col . '</td>');
}

print('  </tr>');
}

print('</table>');

Not the best way of doing it but it'll work.

When you say square, do you mean that the size of the array will always be a square number (1, 4, 9, 16, etc.)? If so, this is a fairly simple exercise.

yes i do mean that and ive been working on it for ages i hope for my iq's sake it isnt...

Here you go:

<?php

$myArray = array('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i');     

// figure out how many rows and columns are needed
$colsAndRows = sqrt( count( $myArray ) );

$col = 0;  // column counter
echo "<table cellspacing=\"0\" cellpadding=\"7\" border=\"1\">\n";
foreach ( $myArray as $val ) {
  if ( !$col ) {
    echo "<tr>\n";  // this is the first cell in a row
  }
  echo "<td>$val</td>\n";  // output array value
  $col++;  // increment array counter

  if ( $col % $colsAndRows == 0 ) {
    echo "</tr>\n";  // this is the last cell in a row
    $col = 0;
  }
}
echo "</table>\n";

?>

I also tested it here:

Hope this helps. It was a fun little problem. And don't worry about not figuring it out. That will come with experience.

thats easy??!?!?!?

well heres was my stab (a little to my credit)

<?php
echo "<table width=\"100%\" border=\"1\">";

//echo "<tr>";
$col = 0;
foreach(array_chunk($files,1)as $file){

if ($col >= 2) {
echo "<tr>";
$col = 0;
} else {
$col++;
}
echo"<td>";

echo $file[0] . "<br />";

echo "</td>";
if ($col >= 2) {
echo "</tr>";
}
}
//echo "</tr>";
echo "</table>";

?>

but the 3rd col 1st row is not there

eg

FILE FILE

FILE FILE FILE

FILE FILE FILE

etc.

also what if count($array) = an odd number

[davo666]

you see, but i dont necessalily need it to be a square, just, well, just like my source code, but with col3row1 showing something!

<table>
<?php
$testData = range(1,9);  // array with 9 elements, values 1 - 9
$rowData = array_chunk($testData, 3);  // 3 columns
foreach($rowData as $row)
{
   echo "<tr>";
   foreach($row as $cell)
   {
      echo "<td>$cell</td>";
   }
   echo "</tr>\n";
}
?>
</table>

yer that worked, how come mine didnt

@: Hey, great solution. I'd say that's simpler and more elegant than mine. I'll have to add array_chunk() to my bag of tricks. Thanks!

Ah, touchet... I'll give you props for knowing about that function too. 😉

Would've been easier to spot if the code had been in &#91;php]...[/code] tags.
