undefined variable: parola

[I-AM-OBODO]

hi all,

pls I dont know why am getting this error undefined variable: parola. but the script runs

thanks

 

<?php

$my_array = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "0", "1", "2", "3", "4", "5");
        for ($i=0; $i<=5; $i++)
        {
            $random = array_rand($my_array);
                        //this generates the random number from the array
		$parola .= $my_array[$random];
                        //here we will display the exact charachter from the array
        }
        echo $parola; // printing result
?>

		$parola .= $my_array[$random];

 

 

That line is the same as $parola = $parola . $my_array[$random]; which means it is trying to first read the existing value of $parola before setting it to the new value.  On your very first iteration of the loop, $parola does not exist because you've never defined it anywhere.  Because it does not exist when php tries to read it you receive that notice.

 

Add $parola = ''; before your loop to define the variable first.
