This program displays the Mersenne numbers that fall within a given range of numbers
To run the script locally in the linux system, just run it on any port:
php -S localhost:8001
then enter the indicated local address in the web browser.
In order to set the number range of interest to us, complete the variables $start and $stop in the MersenneNumberFinder class:
$start = 2;
$stop = 9999;
$rangeOfNumbers = [
'start' => $start,
'stop' => $stop
];
The mersenne numbers found in the specified range then appear on the screen.
Example:
3 7 15 31 63 127 255 511 1023 2047 4095 8191
In case you want to search among a large range of numbers, it is worth uncommenting this line of code:
//ini_set('max_execution_time', '0');
This removes the default php script execution time limit (30 seconds).
