How can PHP handle dynamic variable names within a loop?

When dealing with dynamic variable names within a loop in PHP, you can use variable variables to create and access variables dynamically. This involves using a double dollar sign ($$) followed by the variable name to create a new variable with a dynamic name. By concatenating the loop index or any other dynamic value to the variable name, you can easily handle dynamic variable names within a loop. 

// Example of using variable variables to handle dynamic variable names within a loop
for ($i = 1; $i <= 5; $i++) {
    ${"dynamicVar" . $i} = "Value " . $i;
}

echo $dynamicVar1; // Output: Value 1
echo $dynamicVar2; // Output: Value 2
echo $dynamicVar3; // Output: Value 3
echo $dynamicVar4; // Output: Value 4
echo $dynamicVar5; // Output: Value 5
