Need a string of random numbers

[TristaSD]

Hi,

Need a string of random numbers from 1 to 6 generated by php, none of
the numbers repeat, e.g. 142635, and NOT 114255.

Thanks.

str_shuffle(imp lode('', range(1, 6)));

Subtle hint? :)

echo str_shuffle('12 3456');
print_r(range(1 , 6));
echo implode('', range(1, 6));

All work and no fun makes Jack a dull boy.

I think Trista would have figured it out, once looking in the manual.

Thanks, all. Here's how I used this. If I weren't so lazy, I'd count
the number of pics in a folder so that a user can just upload a pic and
not mess with the $total_number variable in the code :)

<?
$total_number = 6; // Total number of pics

for ($i = 1; $i <= $total_number; $i++) {
$string_to_shuf fle = $string_to_shuf fle . $i;
}

$string_to_shuf fle = str_shuffle ($string_to_shu ffle);

for ($counter = 0; $counter <= strlen ($string_to_shu ffle) - 1;
$counter++) {
echo ("<img src='images/gaslogo_");
echo (substr ($string_to_shu ffle, $counter, 1));
echo (".jpg' alt='some ALT text' ");
echo (substr ($string_to_shu ffle, $counter, 1));
echo ("' /><br />\n");
}
?>

Also, is it a good practice to break echo's like that, or should I
write them as one echo statement (sorry for the drift) ?

If you do it the first way you will go blind. If you do it the second
way, the leprechauns will get you.
