Password geenrator script

We can use this to develop a password generator script where we will create random passwords by using different types of chars. We used substr string function to get short string by taking out first 8 chars of the string only.
Here is the code



$string1="abcdefghijklmnopqrstuvwxyz";

$string2="1234567890";

$string3="!@#$%^&*()_+";

$string=$string1.$string2.$string3;

$string= str_shuffle($string);

echo substr($string,0,8);

we will get 8 char random string to use as password

In above case we have used three stings and added them before shuffling to generate password string. You can add more strings like all uppercase alphabets etc to generate desired password. We can take user inputs also to use the combination of strings to generate random password.
