str1

Example#1 xdiff_string_diff() example

The following code makes unified diff of two articles.


<?php
$old_article = file_get_contents('./old_article.txt');
$new_article = $_REQUEST['article']; /* Let's say that someone pasted a new article to html form */

$diff = xdiff_string_diff($old_article, $new_article, 1);
if (is_string($diff)) {
    echo "Differences between two articles:\n";
    echo $diff;
}

?>

注释

Note: This function doesn't work well with binary strings. To make diff of binary strings use xdiff_string_diff_binary().
