I'm not real clear on what this is...
Choose a string at random from an array?
$possibles = array('ross', 'andrea');
shuffle($possibles);
echo $possibles[0];
Or are you trying to compose a new string of randomly-selected
characters of a bunch of other strings?
Some combination of these functions might be in the recipe:
http://php.net/mt_rand
http://php.net/shuffle
http://php.net/explode

[PHP] Random String Generation
Hello: What I am trying to do is to create a email verification routine with PHP. When people register on the site they will get an email sent to them with a link such as http://mysite.com/activation.php?ID=ghjghjg367ghjlkj9hjlkjhn0 That way when they click on the link it will verify the code against the database and activate their account. Does anyone know an easy way to create this string? Thank you, Mike Walth CinoFusion -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Random String Generation
Mike,
This is can be simple or complex depending on how complex you get.
Here is an example that should work.
function getRandString()
{
$NumOfElements = 5; // Chooses that number of elements from the
Element Array
$ElementArray =
array(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z);
$Total = count($ElementArray);
$String = ;
for ($C=0; $C$NumOfElements; $C++)
{
$RNum = rand(0, $Total);
$String .= $ElementArray[$RNum];
}
return $String;
}
With the settings this functions loops through and creates a string
that is 5 elements in length. You can tell it to add or subtract
numbers by changing the value of NumOfElements or change the elements
that are returned by changing the value of ElementArray.
I hope this helped.

Re: [PHP] Random String Generation
The method I use is to take their user_id or email and create an HMAC (hashed message authentication code) by hashing it with a secret key on my end. This way the activation link looks like the following: http://mysite.com/activation.php?user_id=petejID=ghjghjg367ghjlkj9hjlkj THe activation script takes the user_id they passed in and hashes it with the secret key again. The result should match the ID they passed. Easy and pretty secure. HTH. Pete. Mike Walth wrote: Hello: What I am trying to do is to create a email verification routine with PHP.

what you want to do is use the random string as a verifying of an id... so
their email address gets added to the db, with an id and a random value.
your table may look like this:
id
email
stamp
confirm
Then you send an email out with a link. For the fourth email address you
add, it may look like this:
http://site.com/confirm.php?id=4c=182648
confirm.php grabs the id, checks the confirm code, and if all is well,
resets the confirm code to 1 (true), or yes, or whatever you choose.
To get the random value, include this function that I just wrote for someone
else in a different thread:
?
function randNumber($min=1000,$max=9)
{
// build a seed
list($usec, $sec) = explode(' ', microtime());
$seed = (float) $sec + ((float) $usec * 10);
// seed random generator
srand($seed);
// return random number
return rand($min,$max);
}
?
Since the min is 1000, it will never be '1'.
Hope this helps,
Justin

[PHP] Random string (was Header sent problem)
I found that the Header already sent problem was caused by the Random Password Generator I'm using, even if I place this function on the bottom of the same file I'm trying to open an just call for the result. So, to avoid this issue, I need another method of generating a random number or string of some sort like using the actual time which I can place inside the setcookie function directly... anyone knows what can I use?

If the function is the problem, then stop echoing or printing anything in the function, before it, or after it. Make sure there is nothing outside of the ? And ? tags, especially an extra line break after the closing ? of the file if it's an include file.
