Run a PHP Cron Job on macOS & MAMP - macos

Question

I'm trying to run a cron job on macOS and a site hosted locally using MAMP.
I have tried various options, none to any avail; please see below:
*/1 * * * * php http://mylocalsite.com/cron/my_function
*/1 * * * * /usr/bin/curl –silent –compressed http://mylocalsite.com/cron/my_function
*/1 * * * * /usr/bin/curl --silent --compressed http://mylocalsite.com/cron/my_function
*/1 * * * * /Applications/MAMP/bin/php/php7.1.12/bin/php http://mylocalsite.com/cron/my_function > /dev/null 2>&1
*/1 * * * * wget --no-check-certificate -O- https://mylocalsite.com/cron/my_function >> /dev/null
When I run the following in terminal, it does work:
wget --no-check-certificate -O- https://mylocalsite.com/cron/my_function >> /dev/null
I know that the URL executes the function that I want as I have tested this directly in a browser.
What am I doing wrong and what should go into the crontab in order to ping/run the specified URL?

The CodeIgniter manual suggests that running CodeIgniter through the commandline is possible.
They write the following script:
<?php
class Tools extends CI_Controller {
public function message($to = 'World')
{
echo "Hello {$to}!".PHP_EOL;
}
}
In turn they execute the script like this on the server:
$ cd /path/to/project;
$ php index.php tools message
Where tools denotes the controller, and message the action.
So in that case the crontab entry would become:
*/1 * * * * cd /path/to/project; php index.php tools message
And in the case sketched in the question:
*/1 * * * * cd /path/to/project; php index.php cron my_function

The thing I like to do is:
Make sure you have php installed using brew (brew install php#version (I use php#7.4))
Check if you have crontab, else install using brew install crontab
Enter crontab -l into the terminal, this will open a vim editor. If you can't seem to type anything press the i key. Then start entering the commands like :
*/1 * * * * cd /path/to/project; php index.php
press : and following it enter wq and enter to save and exit the vim, making it :wq
check cronjob using crontab -e in terminal
