PHP Random image 3 images in a row

[fastrod]

I have a random image script.
But I want so that 3 different photos you can see in a row.

I have therefore tried

Code:

<?
$ folder = ". / screens / '/ / The directory of the images a. for the same folder where this file.

$ dir = opendir ($ folder);
/ / Get the data dir
while (false! == ($ file = readdir ($ dir)))
(
if (($ file! == ".") & & ($ file! == ".."))
(
list ($ filename, $ ext) = explode (".", $ file);
$ ext = strtolower ($ ext);
if (($ ext == "jpg") | | ($ ext == "png") | | ($ ext == "poison"))
(
$ image [] = $ file;
)
(
$ afbeelding2 [] = $ file;
)
(
$ afbeelding3 [] = $ file;
)
)
)
closedir ($ dir);

/ / Counts number of images in folder and creates a random number from that number.
$ number = count ($ image) - 1;
$ rand = mt_rand (0, $ number);
echo "<img src=\"".$map. $afbeelding[$rand]."\" width=136 height=111>;
echo '';
echo "";
echo "<img src=\"".$map. $afbeelding2[$rand]."\" width=136 height=111>;
echo '';
echo "";
echo "<img src=\"".$map. $afbeelding3[$rand]."\" width=136 height=111>;
>

but that does not work: (I still get 3 the same pictures in a row.

I would also like to have them clickable so that if there is a popup with the photo.

Do you love that you see the same photo 3x ..? Then you something better to look at your code.

You take in 3x the same random value from a 'copy' of the same array. When you first check whether the extension matches (and that is probably in your case always) and in the other arrays, all files (in your case the same as array 1).

Instead of the 3 arrays can better address 3x a random number and compare with the numbers that you already had it

[MindSpace]

Clickable images, for example, :


php:

<?
echo "<a href=\"" . $afbeelding [ $rand ]. "\"><img src=\"" . $map . $afbeelding [ $rand ]. "\" width=136 height=111></a>" ;
?>

Keeping the picture you have already used. And in this case you would the photo from the array may flicker.

For the same topic to a conclusion:
After the folder is selected, place the following code:

php:

<?
$ number = count ($ image) - 1;
$ i = 0;
$ selected = array (), / / array to create images which are
while ($ i <3) (
$ rand = mt_rand (0, $ number);
if (in_array ($ rand, $ selected)) (
/ / do nothing graphic is selected
) else (
/ / Add image to $ selected images
$ selected images [] = $ rand;
$ i + +;
)
)
/ / ok 3 selected still image display
foreach ($ selected images as $ value) (
echo "<a href=\"". $map. $value. "\"> <img src=\"". $map. $value. "\" width=136 height=111> </ a>";
)
