OK, at the moment, my script for free image hosting, renames all files uploaded to completely random numbers.

Here is the code it uses for the random numbers:

{
$number2 = rand(0,100000000) . substr($name, -5, 5);
}
else
{
$number2 = rand(0,100000000) . substr($name, -4, 4);
}

and here is the code for the name that it gathers (something like that)

$name

So, Basically;

User Selects image 'banner.jpg' ($name)
User Presses Upload, and it renames it to something like 287193.jpg

how do I change it so:
User Presses Upload, and it renames it to something like bann282.jpg (or even banner928.jpg)?

I hope I made myself clear

anyone? or am i not making sense?

Something like this:

<?php

$name = "ban";
$number2 = substr($name, -3, 3) .rand(0,1000); 


echo $number2;



?>

For me this outputted ban480

i am still confused

you understand that banner is just an example, yes?

$name is what you want the beginning part to be, you can just get the filename and make that $name instead.
$number2 = substr($name, -3, 3) .rand(0,1000); takes 3 characters off $name and adds a random number from 0-1000.

ok, thanks, i will try that

edit//

ok i replaced the code i put in the first post with:

{
$number2 = substr($name, -3, 3) .rand(0,1000);
}
else
{
$number2 = substr($name, -3, 3) .rand(0,1000);
}

and it renamed it to: png473 , which of course is not right, it has no extention.
Help, plz?

edit again//
i realise now that it took off the first 3 characters, the image was called bg.png and it took off bg. . this is not good:- is there another way to do this that works on all image names?

This is a working example. bannnnwwe.jpg is here the full filename with the extension, and will print out ban and 3 random numbers, and .jpg in this case. I have tested it, and it works.

$name = "bannnnwwe.jpg";
$number2 = substr($name, 0, 4) .rand(0,1000) .substr($name,-4,4); 


echo $number2;

When I ran this example, it printed out

bann219.jpg

 

[themoose]

yup, that works, thanks
I also tested it with an image with a short filename, bg.png, and it came out bg.p456.png, which works.
Thanks
