why my shuffle not working please.

 

debugged every think nothing wrong.

<?php

function user_password(){

$passwords[]="0123456789abcdefghijklmnopqurstuvwxyz";


shuffle($passwords);


$password=substr($passwords[0],0,7);


return $password;

}

echo user_password($password);

?>

shuffle is for arrays....you have an array with one element...you want to shuffle a string...use this instead:

 

<?php

function user_password(){

   $passwords = "0123456789abcdefghijklmnopqurstuvwxyz";


   $password=substr(str_shuffle($passwords),0,7);


   return $password;

}

echo user_password($password);

?>

Shuffle randomizes the elements in the array.  You only have 1.  There's nothing else to shuffle...

[printf]

shuffle takes an array of key names => key values, you're giving it a single key_name => key_value, so there is nothing to shuffle... Also I really hope you are not planing to generate passwords that way!

printf makes a good point....this isn't a good way to make a password. limiting the possible lets to only 1 of each letter reduces the number of possibilities
