How to generate random password with PHP?

Question

Or is there a software to auto generate random passwords?

Answer 1

I think better way to generate random password is below function, if someone want then you can use these for strong password

public function randPassword($upper = 2, $lower = 3, $numeric = 2, $other = 1) { 

        $pass_order = Array(); 
        $passWord = ''; 

        //Create contents of the password 
        for ($i = 0; $i < $upper; $i++) { 
            $pass_order[] = chr(rand(65, 90)); 
        } 
        for ($i = 0; $i < $lower; $i++) { 
            $pass_order[] = chr(rand(97, 122)); 
        } 
        for ($i = 0; $i < $numeric; $i++) { 
            $pass_order[] = chr(rand(48, 57)); 
        } 
        for ($i = 0; $i < $other; $i++) { 
            $pass_order[] = chr(rand(33, 47)); 
        } 

        //using shuffle() to shuffle the order
        shuffle($pass_order); 

        //Final password string 
        foreach ($pass_order as $char) { 
            $passWord .= $char; 
        } 
        return $passWord; 
    }
