If you want to sort array data, just use function sort() or natsort()

 

PHP has native functions for both tasks, therefore you really don't need any logic to accomplish what you want to do:

<?php
$contents = file_get_contents('movies.txt');					// Get the file contents
$originalArray = array_map('trim', explode("\n", $contents));	// Separate the values to into an array
$finalArray = array_unique($originalArray);						// Remove duplicated entries
sort($finalArray, SORT_STRING);									// Sort the array
$contents = implode("\n", $finalArray);							// Turn the new array back into a string
file_put_contents('movies.txt', $contents);						// Write it to the file

Thanks proactiv3

it is possible to show only data of start with alphabet C

 

$movies = array("Carnage", "Like Crazy", "Our Idiot Brother", "Carjacked", "Moneyball");
foreach ($movies as &$value) {
    $first_letter = substr($value, 0, 1);
    if (strtoupper($first_letter == "C")) {
        echo $value."<br />";
    }
}
