shuffle

ThinkGeekness

I am trying to shuffle some images using:
shuffle()

Here is the code I have:

		  <?php
		  $pictures = array('image/image1', 'image/image2', etc);
		  srand ((float)microtime()*1000000);
		  shuffle($pictures);
		  {
		  echo '<div align="right"><img src="';
		  echo $pictures;
		  echo 'width="226" height="103"></div></td>';
		  }
		  ?>

It is giving me a broken image. What needs to be changed?

make sure you have the extensions on the image names?

etc.. image1.gif, image2.jpg

and make sure they exist :-/

yep, they do exist. If I view the image properties, it says the location of the image is:

http://www.site.net/Arraywidth=

So it looks like it is a problem with the coding.

ahh.. i see it now

you have

echo $pictures

but $pictures is an array, not an individual picture

you will have to say:

echo $pictures[0];
or
echo $pictures[1];

etc..

That works, only it doesn't shuffle the pictures. Do you know how to get it to shuffle?

I have been playing with it a bit, and I think you need something like:

for ( $i = 0; $i <1, $i++ )
{
echo $pictures[$i]
}

shuffle shuffles the keys as well so that they stay paired up with their values. So what was $pictures[0] before will still be $pictures[0] afterwards.

You'll want to reindex the array. [man]array_values[/man] is a straightforward way of doing it.
