Looping through Array in multiple <td> cells - php

Question

Lets say I have an array
$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");
Now displaying one array value in one table row is easy like this
echo "<table>";
foreach ($aSomeArray as $iSomeArrayKey => $iSomeArrayValue)
{
echo "<tr>";
echo "<td>".$iSomeArrayValue."</td>";
echo "</tr>";
}
echo "</table>";
But I want to display the values in table format like this
1 2 3 4
5 6 7 8
9 10 11 12
How can I achieve this ?

Answer 1

Edited, this works:
$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");
$i = 0;
echo "<table>\r\n";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{
if (($i % 4) == 0) echo "\t<tr>\r\n";
echo "\t\t<td>" . $aSomeArrayValue . "</td>\r\n";
if (($i % 4) == 3) echo "\t</tr>\r\n";
$i++;
}
echo "</table>\r\n";

Answer 2

Just a thought which seems nicer IMHO.
<?php
$aSomeArray = array("1","2","3","4","5","6","7","8","9","10","11","12");
function createMatrix($width, $array)
{
$newArray = array();
$temp = array();
$count = 1;
foreach($array as $key => $value)
{
$temp[] = $value;
if(($count++ % $width) == 0)
{
$newArray[] = $temp;
$temp = array();
}
}
if( count($temp) > 0)
{
$newArray[] = $temp;
}
return $newArray;
}
will create a matrix array of variable $width
You can then use that data as a double for-each like this:
$matrix = createMatrix(2, $aSomeArray );
foreach($matrix as $row)
{
echo "<tr>\n";
foreach($row as $td)
{
echo "\t<td>{$td}</td>\n";
}
echo "</tr>\n";
}
Which produces:
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>8</td>
</tr>
<tr>
<td>9</td>
<td>10</td>
</tr>
<tr>
<td>11</td>
<td>12</td>
</tr>

Answer 3

Just do a running count. So before the foreach set $i = 1 and every fourth result, reset the count to $i = 1 and then end the row and re-open a new row.

Answer 4

$aSomeArray = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13");
$columns = 4; // The number of columns to shown
echo "<table>";
$i = 0;
$trOpen = false; // just a flag if <tr> has been closed (paired with </tr>) or not.
foreach ($aSomeArray as $item) {
if ($i % $columns == 0) {
echo "<tr>";
$trOpen = true;
}
echo "<td>" . $item . "</td>";
if (($i + 1) % $columns == 0) {
echo "</tr>";
$trOpen = false;
}
$i++;
}
if ($trOpen) {
echo "</tr>"; // add '</tr>' if it is not yet added.
}
echo "</table>";

Answer 5

$i=1;
echo "<tr>";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{
echo "<td>".$aSomeArrayValue."</td>";
$i++;
if($i%4==0){
echo "<tr></tr>";
}
}
echo "</tr>";
It will also work for the indivisible by 4 number of elements.

Answer 6

echo "<table>";
echo "<tr>";
foreach ($aSomeArray as $aSomeArrayKey => $aSomeArrayValue)
{
echo "<td>".$aSomeArrayValue."</td>";
if($aSomeArrayValue % 4 == 0)
echo "</tr><tr>";
}
echo "</tr>";
echo "</table>";

Answer 7

Try this code
<?php
$i=0;
echo"<table>";
echo"<tr>";
foreach($aSomeArrayas as $val)
{
if($i %4 ==0)
{
echo"</tr><tr> <td> $val</td>";
}
else
{
echo"<td> $val </td>";
}
$i++;
}
echo"</tr>";
echo"</table>";
?>
