Forming Columns

[Disturbed One]

Hello,

 

I have an array I want to put into three equal columns (each one starting with <ul> and ending with </ul>).

 

The array is dynamic, and can have anywhere from a few entries to 30.

 

$array = array(
'item1' => 'Item 1',
'item2' => 'Item 2',
'item3' => 'Item 3',
'item4' => 'Item 4',
'item5' => 'Item 5',
'item6' => 'Item 6',
'item7' => 'Item 7',
'item4' => 'Item 8',
'item5' => 'Item 9',
'item6' => 'Item 10',
'item7' => 'Item 11',
);

 

Should output

<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
<ul>
<li>Item 5</li>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
</ul>
<ul>
<li>Item 9</li>
<li>Item 10</li>
<li>Item 11</li>
</ul>

 

$array = array(
'item1' => 'Item 1',
'item2' => 'Item 2',
'item3' => 'Item 3',
'item4' => 'Item 4',
);

 

Should output

<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
<ul>
<li>Item 3</li>
</ul>
<ul>
<li>Item 4</li>
</ul>

 

And so on.

 

How can I accomplish this?

 

Thanks!

First, get the sizeof the array, then do a loop where that size is divided by 3.

How do I divide the loop by three? I know how to count the number of values in the array.

I've almost got something sorted. I'm off to bed now though but I'll get back to you once it's finished.

try

<?php
$array = array('item1' => 'Item 1', 'item2' => 'Item 2', 'item3' => 'Item 3',
			'item4' => 'Item 4', 'item5' => 'Item 5', 'item6' => 'Item 6',
			'item7' => 'Item 7', 'item8' => 'Item 8', 'item9' => 'Item 9',
			'item10' => 'Item 10', 'item11' => 'Item 11');
$num_of_list = 3;
$total_item = count($array);
$ends = array(0);
while ($num_of_list > 0) {
$a = ceil($total_item / $num_of_list);
$ends[] = $a + max($ends);
$total_item -= $a;
$num_of_list--;
}
$i = 0;
foreach ($array as $item){
if (in_array($i, $ends)) echo "<ul>\n";
$i++;
echo "<li>$item</li>\n";
if (in_array($i, $ends)) echo "</ul>\n";
}
?>

Damn looks like someone beat me to it. This is what I managed to cook up anyway if you're interested:

 

<?php
$n = count($array);
$r = $n % 3;
$colsize = floor($n / 3);
$newcol = false;
$tmp = $colsize;
echo "<ul>\n";
foreach($array as $item) {
	if($tmp < 1) {
		if($r > 0 && $tmp > -1) $r--;
		else {
			$newcol = true;
			$tmp = $colsize;
		}
	} else $newcol = false;
	if($newcol) echo "</ul>\n<ul>\n";
	echo "\t<li>$item</li>\n";
	$tmp--;
}
echo '</ul>';
?>

 

Should work for any number of columns and array lengths, just change both the 3s up at the top to however many columns you need.
