![### Removing Duplicates from a Sorted List in PHP
#### Problem Statement
Given a sorted list, the task is to write a PHP program to remove duplicates from the list.
#### Example
**Given List:**
\[ (11, 11, 32, 32, 32, 44, 57, 57) \]
**Expected Output:**
\[ (11, 32, 44, 57) \]
#### Solution Approach
1. **Initialize an Array:** Start with the given sorted array, which contains duplicate values.
2. **Iterate through the List:** Loop through each element of the array.
3. **Comparison:** Check each element with the next element.
4. **Store Unique Elements:** If the current element is not equal to the next element, store it in a new result array.
5. **Output the Result:** Once done, the result array will contain only the unique elements.
#### PHP Code Example
```php
function removeDuplicates($list) {
$result = []; // Initialize an empty array to store unique values
$length = count($list);
for ($i = 0; $i < $length; $i++) {
// Compare current element with the next, add to result if different
if ($i == $length - 1 || $list[$i] != $list[$i + 1]) {
$result[] = $list[$i];
}
}
return $result;
}
$givenList = [11, 11, 32, 32, 32, 44, 57, 57];
$expectedOutput = removeDuplicates($givenList);
print_r($expectedOutput);
```
This code effectively removes duplicates from a sorted list and outputs the expected unique list.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43f06054-628c-44f0-8ccf-50b954204ffb%2F8e1c4f90-65e5-4982-887b-57337ef05af5%2F2wjziya_processed.jpeg&w=3840&q=75)

$expectedOutput = removeDuplicates($givenList);
print_r($expectedOutput);
```
This code effectively removes duplicates from a sorted list and outputs the expected unique list.
