PHP - Check Order Of Array From 1 Through 9 Only

Hello all,

I need to make a rotating banner system for a client. They want about 5 banners to rotate with Javascript. However they want the visitor to sort of step through each one on each refresh.

So if I have 5 banners and I go to the site, I see banner 1 and then the javascript rotates through each one.

When I go back to the site, they want it to start with banner 2 and then the javascript will rotate through each one. Then on and on. Go back and see banner 3, then step through again.

I have a nice Javascript image slider I'd like to use. It basically just requires the images in order. Like:

<img src="1.jpg"/>
<img src="2.jpg"/>
<img src="3.jpg"/>
<img src="4.jpg"/>
<img src="5.jpg"/>

I've thought about it and I think the best way to do this would just be using PHP and a cookie. So when the viewer first goes to the site, PHP checks for the cookie. If it exists, it pulls the starting image #. If it doesn't, it starts at 0 and sets the cookie.

As for the images part, I figured an associate array would work well. The key would be what the cookie logic is based on, and then the image HTML would be in the array.

So you visit the site without a cookie it would be...

0 => <img src="1.jpg"/>
1 => <img src="2.jpg"/>
2 => <img src="3.jpg"/>
3 => <img src="4.jpg"/>
4 => <img src="5.jpg"/>

Then when you go back to the site, I need the array to be re-ordered like this:

0 => <img src="2.jpg"/>
1 => <img src="3.jpg"/>
2 => <img src="4.jpg"/>
3 => <img src="5.jpg"/>
4 => <img src="1.jpg"/>

What's the best way to go about this array logic? My experience with manipulating data inside arrays is rather limited. Basically I need it to say "Start with key # and then reorder array based on that"

Hi guys,

I'm trying to sort an array. The array has information about listings. ID, name, info etc.

An unrelated set of data also contains the listing ID's and I have made a function to sort this array and show an new order for the ID's. I now need to sort the original array by this new ID order...

This snippet shows that the original listings array can be sorted by link_id:
sort($this->links, $this->link->link_id); //This works. It sorts links by link ID!

In a foeach loop I have created this:
$sleeps_array[] = array("ID" => $link->link_id, "Sleeps" => $sleeps); // Makes an array of arrays of a custom field with listing ID.

It makes this:
array ( 0 => array ( 'ID' => '9', 'Sleeps' => '2', ), 1 => array ( 'ID' => '3', 'Sleeps' => '4', ), 2 => array ( 'ID' => '6', 'Sleeps' => '6', ), )

I can then sort this array of arrays with this function:

function compare_sleeps($a, $b){
return strnatcmp($a['Sleeps'], $b['Sleeps']);
} # sort alphabetically by name
usort($sleeps_array, 'compare_sleeps');

It then gives me a sorted array according to "Sleeps" (as in, the number of people a property can cater for). It has the correct order of ID to then output but how do I organise the original array by ID with this new array?

Sounds complicated, I hope you got that!

Hi, I've been trying to re-order an array and I can't seem to even do it let alone neatly. I've ran out of time and would appreciate any help!


$array = array(
  '0' => array(
    'filepath' => 'files/image_site1.png',
    'title' => 'Website',
  ),
  '1' => array(
    'filepath' => 'files/image_id.png',
    'title' => 'Identitity',
  ),
  '2' => array(
    'filepath' => 'files/image_site2.png',
    'title' => 'Website',
  )
)

I'm looking to re-order the arrays within the parent array depending on whether the 'filepath's contain a sub string of '_id' or '_site'.

I've been using:
$type = '_site';
foreach ($array as $item){
  if (preg_match("/$type/i", $item['filename'])){
    //add this $item to the top of array, somehow...
  }
}

So with $type set to '_site', I'd like to re-arrange the array so both arrays containing _site1.png and _site2.png appear at the top of the parent array. I.e:
$array('0' = array(...), '2' => array(...), '1' => array(...));

I hope I've explained it well enough.

Thanks,

i have checkboxes in a form with the name="array[]" and in the php i use the implode function to separate all the values of all that was checked with a comma....my question is... how can i set the order of the array a certain way... i'd like to ultimately have a field where if you check a box you can enter into the field 1, 2, 3, 4 and so on and when you submit the form it will set the order according to what was entered

thanks

Hi, I have this php code to display the url of the files and it works fine, it just has a weird order when it is echoed out.
Here is the code: Code: [Select]
<?php
$date = date("Y-m-d");
$picarray = array();
        $handle = opendir ('pqimages/'.$date.'/');
        while (false !== ($file = readdir($handle))) {
            if($file != "." && $file != "..") {
                $picarray[] = "http://randomaydesigns.com/pqimages/".$date."/".$file."";
            }
        }
$json_array = json_encode($picarray); 
echo $json_array;  
?>There are three files in the folder and they are 33,34,35.jpg it displays them like 33,35,34.jpg

Any Recommendations?
Thanks,
GEORGE
