How can conflicts between variables in PHP includes be resolved effectively?

Conflicts between variables in PHP includes can be resolved effectively by using namespaces to encapsulate the variables within a specific context. This helps prevent variable name collisions and ensures that each variable is properly scoped.

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

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

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

echo MyNamespace\$variable; // Output: File1
