1. PHP Random password generation Write a PHP function to generate a random password. The password should contain uppercase, lowercase, numeric and other Create password using shuffle() function.
function generate_password($length = 12) {
// Define all possible characters that can be used in the password
$uppercase = range('A', 'Z');
$lowercase = range('a', 'z');
$numbers = range('0', '9');
$special_chars = str_split('!@#$%^&*()_+={}[];\',.');
// Combine all characters into a single array
$all_chars = array_merge($uppercase, $lowercase, $numbers, $special_chars);
// Shuffle the array
shuffle($all_chars);
// Take a random subset of the shuffled array to create the password
$password = array_slice($all_chars, 0, $length);
// Convert the array to a string
$password = implode('', $password);
// Return the password
return $password;
}First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
