Regular Expressions

[kiwi_uk]

is there a way or function to populate an array using Regular expressions? e.g

$my_array = array([A-z]);

At the moment I have writen my own function to do it:

function makeAZ() {
$pool = "";
for($i = 48; $i <= 57; $i++) {
$pool .= chr($i);
// return($pool);
}
for($i = 65; $i <= 90; $i++) {
$pool .= chr($i);
// return($pool);
}
for($i = 97; $i <= 122; $i++) {
$pool .= chr($i);
// return($pool);
}
return($pool);
}

for($i=0;$i<=strlen(makeAZ()) - 1; $i++) {
$array1[] = substr(makeAZ(),$i,1);
}

for($i=0; $i<=20; $i++) {
mt_srand((double)microtime()*1000000);
$ranNum = mt_rand(0,count($array1) - 1);
$custID .= $array1[$ranNum];
}

What is the purpose for creating this array of characters?

To generate a userId for seeesions. It may not be a good way but it works. I was wondering if this can be done as Perl can do it.

if you want to generate a unique identifier, the uniqid() function will create one based on the current time in microseconds. This may be a better solution for you:
