For loop

[harkly]

I have this code that generates a random string of numbers & letters. It works just fine but I need help with taking the variable $newPassword out of the for loop. I ultimately want to be able to email the $newPassword.

 

Code that works ...

<?php 
for ($i=0; $i<7; $i++) { 
    $d=rand(1,9)%2; 
    $newPassword= $d ? chr(rand(65,90)) : chr(rand(48,57)); 
echo $newPassword; 
} 
?>

 

 

Would like to be able to echo it outside of the for loop, right now it just echos 1 number or letter....

<?php 
for ($i=0; $i<7; $i++) { 
    $d=rand(1,9)%2; 
    $newPassword= $d ? chr(rand(65,90)) : chr(rand(48,57)); 
} 

echo $newPassword; 

?>

something like this:

<?php 
for ($i=0; $i<7; $i++) { 
    $d=rand(1,9)%2; 
    $newPassword= $newPassword.$d ? chr(rand(65,90)) : chr(rand(48,57)); 
    // OR us .=  like so....   $newPassword.= $d ? chr(rand(65,90)) : chr(rand(48,57)); 
} 

?>

How about something like:

<?php
$numslets = array_merge(range(0,9),range('a','z'),range('A','Z'));
shuffle($numslets);
$newPassword = implode('',array_slice($numslets,0,7));
echo $newPassword;
?>

kenrbnsn your idea works great! I didn't think I really needed a for loop

 

Thanks!
