www.php.bet to look up those two functions =)

www.php.bet? i think its .net anyways i have no clue what you just said after all im a total php newbie

---

lol, you aint gonna learn if i give you the code are you?

code:

---

<?php
$dir    = '/tmp';
$files1 = scandir($dir);

print_r($files1);
?>

---

that code gets and displays all contents of a folder.

code:

---

echo substr('abcdef', -1, 1); // f

---

prints f.

so you could go.

code:

---

$dir    = '/images';
$files1 = scandir($dir);

for ($x=0;$x<count($files1);$x++){
if (substr($files1[$x], -1, 3) == 'jpg') {
$images[] = $files1[$x];
print_r ($images);
}
}

---

now all the images in the folder are in the $images array.

now we get a random number.

code:

---

$num = rand(0, count($files1));

---

all code.

code:

---

$dir    = '/images';
$files1 = scandir($dir);

for ($x=0;$x<count($files1);$x++){
if (substr($files1[$x], -1, 3) == 'jpg') {
$images[] = $files1[$x];
print_r ($images);
}
}
$num = rand(0, count($files1));
echo "<img src='$dir/$images[$num]' />

---

its not the cleanest way to write it but i should work (not at home at the moment)
