[SOLVED] Illegal offset when using an array

[cheesycarrion]

I'll post the entire script since I don't know exactly what the problem is. the error I get is "Warning: Illegal offset type in /home/cheebac8/public_html/videostest.php on line 72." I marked line 72 with a note below:

 

<?php

$mediadir = @scandir("cc08/media");
$i = 0;
foreach ($mediadir as $foldername)
{
if ($foldername=="."||$foldername==".."||$foldername=="error_log"||$foldername==".htaccess")
	{
	// do nothing
	}
else
	{
	$itemlist = @scandir("cc08/media/" . $foldername);
		foreach ($itemlist as $itemname)
		{
		if ($itemname=="."||$itemname==".."||$itemname=="error_log"||$itemname==".htaccess")
			{
			// do nothing
			}
		else
			{
			$catarray[$i] = $itemname;
			$i++;
			}
		}
	}
}
// print_r($catarray);    // all games and videos displayed in a list
foreach($catarray as $key => $val)
{
$explosion[$key] = explode("-",$val);
}
// print_r($explosion);    // all media files in an array showing name, uploader and tag
////////////////////////////////////////////////////////////////////////////////////////////////////////////
echo "<hr />";
foreach($explosion as $item)
{
if (isset($item[2]))
	{
	// tagged
	$tagname = $item[1];
	$num_other_taggeds = count($tags[$tagname]);
	$tags[$tagname][$num_other_taggeds][0] = $item[0];
	$tags[$tagname][$num_other_taggeds][1] = $item[1];
	$tags[$tagname][$num_other_taggeds][2] = $item[2];
	}
else
	{
	//$tagname = "untagged";
	//$num_other_taggeds = count($tags[$tagname]);
	//$tags[$tagname][$num_other_taggeds][0] = $item[0];
	//$tags[$tagname][$num_other_taggeds][1] = $item[1];
	}
}
// print_r($tags);    // organizes items by tag category
function tagged_video_section($tags)
{
foreach ($tags as $category)
	{
?>

<div class="object">
<div class="object_head">
<a name="<?php
	echo $tags[$category][0][1] . "\">" . $tags[$category][0][1];
	?></a>
</div>
<div class="object_cont">
<ul>
<?php
	$i = 0;
	while (isset($tags[$category][$i][0]))  // line 72
		{
		echo "<li><a href=\"" . $items[0] . "-" . $items[1] . "-" . $items[2] . "\">" . preg_replace("/_/"," ",$items[0]) . "</a></li>\n";
		$i++;
		}

	//$catitems = $tags[$category];
	//foreach ($catitems as $items)
	//	{
	//	echo "<li><a href=\"" . $items[0] . "-" . $items[1] . "-" . $items[2] . "\">" . preg_replace("/_/"," ",$items[0]) . "</a></li>\n";
	//	}
?>
</ul>
</div>
</div>

<?php
	}
}
tagged_video_section($tags);
?>

(the code from line 78 to 82 was my first attempt, which got me the same error. I just decided to try a different approach but it didn't help me.)

 

any help is appreciated.

also, while I'm here, I get this other error "Warning: Invalid argument supplied for foreach() in /home/cheebac8/public_html/videostest.php on line 14" but that's nothing to worry about since it doesn't mess up the script. I'll find a way to hide it later.

line 72 has me beat i got a similar error a while back and i can't remember how i fixed it but i think i can help you on line 14 i believe the error comes form $itemlist not being an array. you could add a line like this before it

if(is_array($itemlist)){

the close the if the other side of the for each

well $tags is a 3d array so in your foreach ($tags as $category) {...} $category is an array also and you're trying to use an array as an element position.

[ratcateme]

from what Crayon Violent said i would think it should be

function tagged_video_section($tags)
{
foreach ($tags as $key => $category)
	{

and

$i = 0;
	while (isset($tags[$key][$i][0]))  // line 72
		{
		echo "<li><a href=\"" . $items[0] . "-" . $items[1] . "-" . $items[2] . "\">" . preg_replace("/_/"," ",$items[0]) . "</a></li>\n";
		$i++;
		}

Ok, thank's ratcateme. you're fix for line 14 also worked, and now I get what Crayon Violent meant. It works now. I also fixed some other instances where I made the same mistake.
