How can variable conflicts be avoided when including multiple PHP files in a project?

Variable conflicts can be avoided by using namespaces to encapsulate variables within a specific scope. By defining unique namespaces for each included file, variables with the same name can coexist without conflicts. This ensures that variables are properly isolated and do not interfere with each other. 

// File1.php
namespace File1;
$variable = "File1";

// File2.php
namespace File2;
$variable = "File2";

// Main.php
include 'File1.php';
include 'File2.php';

echo \File1\$variable; // Outputs "File1"
echo \File2\$variable; // Outputs "File2"
