PHP Array: Exercise-27 with Solution

Write a PHP function to generate a random password (contains uppercase, lowercase, numeric and other) using shuffle() function.

Sample Solution:

PHP Code:

function rand_Pass($upper = 1, $lower = 5, $numeric = 3, $other = 2) { 
    $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

    //Final password string 
    foreach ($pass_order as $char) { 
        $passWord .= $char; 
    return $passWord; 
echo "\n"."Generated Password : ".rand_Pass()."\n";

PHP: Tips of the Day

PHP: Where does PHP store the error log? (php5, apache, fastcgi, cpanel)

PHP stores error logs in /var/log/apache2 if PHP is an apache2 module. Shared hosts are often storing log files in your root directory /log subfolder. But...if you have access to a php.ini file you can do this:

error_log = /var/log/php-scripts.log

According to rinogo's comment: If you're using cPanel, the master log file you're probably looking for is stored (by default) at


If all else fails you can check the location of the log file using

<?php phpinfo(); ?>
