PHP Array Exercises : Generate a random password using shuffle() function
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:
<?php
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++) {
$pass_order[] = chr(rand(33, 47));
}
//using shuffle() to shuffle the order
shuffle($pass_order);
//Final password string
foreach ($pass_order as $char) {
$passWord .= $char;
}
return $passWord;
}
echo "\n"."Generated Password : ".rand_Pass()."\n";
?>
Sample Output:
Generated Password : h1'1#h7Gqfy

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
/usr/local/apache/logs/error_log
If all else fails you can check the location of the log file using
<?php phpinfo(); ?>
