how do i grab and print on page in date order all .jpg files in a folder ?

Hello


I have a simple question about file handling...


Is it possible to list all files in directories / subdirectories, and then read ALL files in those dirs,
and put the content of their file into an array?

Like this:

array:
[SomePath/test.php] = "All In this php file is being read by a new smart function!";
[SomePath/Weird/hello.txt = "Hello world. This is me and im just trying to get some help!";

and so on, until no further files exists in that rootdir.

All my attempts went totally crazy and none of them works... therefore i need to ask you for help.


Do you have any ideas how to do this?
If so, how can I be able to do it?


Thanks in Advance, pros

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!
