How does PHP execution work when accessing a server from a different PC through MAMP (XAMPP for Mac)?

When accessing a server from a different PC through MAMP (or XAMPP for Mac), the server needs to be configured to allow external connections. This can be done by adjusting the server settings to listen on all network interfaces, not just localhost. Additionally, firewalls on both the server and the accessing PC may need to be configured to allow traffic on the necessary ports.

// Example code to configure MAMP to allow external connections
// Edit the httpd.conf file located in MAMP/conf/apache
// Change the line "Listen 8888" to "Listen 0.0.0.0:8888" to listen on all network interfaces
// Restart MAMP for the changes to take effect
