<p>How can I generate a (pseudo)random alpha-numeric string, something like: 'd79jd8c' in PHP?</p>

First make a string with all your possible characters:
```
```
$characters = 'abcdefghijklmnopqrstuvwxyz0123456789';
```
```
You could also use
range()
to do this more quickly.
Then, in a loop, choose a random number and use it as the index to the
```
$characters
```
string to get a random character, and append it to your string:
```
```
$string = '';
 $max = strlen($characters) - 1;
 for ($i = 0; $i < $random_string_length; $i++) {
      $string .= $characters[mt_rand(0, $max)];
 }
```
```
```
$random_string_length
```
is the length of the random string.
