[Resolved] Drop a specific array key.

[Kudose]

Hello all, I feel kinda dumb for having to ask, so please don't make it any worse on me.

How do you drop / remove a specific kay from an array.

ie. I have a 10 key array, and I want to drop key 5.

TIA.

Use :
unset

Welp...this just wiped my column completely and updated it with "Array".

Can you help?

$id = $_GET['id'];
$images = explode(",", $images);
unset($images[$id]);
$images = implode(",", $images);

$images is an string delimited by comma. When I update my database with the $images variable righ tafter the implode, it inputs Array.

Thanks.

Using this:

$images = $myDb->dbFetch("SELECT img1 FROM ".$prefix."inventory WHERE uid='".$id."'");
		$images = explode(",", $images[0]['img1']);
		$image_del = $images[$id];
		unset($image_del);
		$images = implode(",", $images);

I can get the array to implode and print, but it doesn't drop the key, in this case 1. It seems to do nothing.

TIA.

ok - well the logic is flawed in the second example:

  $images = explode(",", $images[0]['img1']);
        $image_del = $images[$id];
        unset($image_del);
        $images = implode(",", $images);

Doesn't do anything because it just unsets $image_del - which you don't use - you repack up images - which you haven't changed!

Try putting some debugging in so you understand what is going on!:

$id = $_GET['id'];
echo('ID (array Column to be unset): '.$id.'<br />');
$images = explode(",", $images);
echo('Images in array format : <br />');
print_r($images);
unset($images[$id]);
echo('<br /> Images after unset:: <br />');
print_r($images);
$images = implode(",", $images);
echo('<br />Images in list format: <br />');
print_r($images);

See what that tells you...

That wasn't the problem, but thanks.

I was trying to unset the wrong array key value.

[RossC0]

so its sorted now? 🙂

To an extent, it will allow me to delete every key other than 0.

if(($_GET['del']) && ($_GET['del'] != "")){
		$_GET['action'] = "edit";
		$id = $_GET['id'];
		$del_img = $_GET['del'];
		$images = $myDb->dbFetch("SELECT img1 FROM ".$prefix."inventory WHERE uid='".$id."'");
		$images = explode(",", $images[0]['img1']);
		$image_del = $images[$del];
		unset($images[$del]);
		$images = implode(",", $images);
		if(($myDb->dbQuery("UPDATE ".$prefix."inventory SET img1='".$images."' WHERE uid='".$id."'")) !== FALSE){
			if(file_exists($tb_config[0]['dir']."imgs/".$image_del)){
				@unlink($tb_config[0]['dir']."imgs/".$image_del);
				@unlink($tb_config[0]['dir']."imgs/thumb_".$image_del);
				echo 'Image removed.';
			} else {
				echo 'Could not find file to delete.';
			}
		} else {
			echo 'Could not remove image from database.';
		}		

}

You totally rock for the unset solution for the array keys, btw.
