xdiff_string_diffMake unified diff of two strings

Описание

string xdiff_string_diff ( string $old_data , string $new_data [, int $context = 3 [, bool $minimal = false ]] )

Makes an unified diff containing differences between old_data string and new_data string and returns it. The resulting diff is human-readable. An optional context parameter specifies how many lines of context should be added around each change. Setting minimal parameter to true will result in outputting the shortest patch file possible (can take a long time).

Список параметров

old_data

First string with data. It acts as "old" data.

new_data

Second string with data. It acts as "new" data.

context

Indicates how many lines of context you want to include in the diff result.

minimal

Set this parameter to TRUE if you want to minimalize the size of the result (can take a long time).

Возвращаемые значения

Примеры

Пример #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$new_article1);
if (
is_string($diff)) {
    echo 
"Differences between two articles:\n";
    echo 
$diff;
}

?>

Примечания

Замечание:

This function doesn't work well with binary strings. To make diff of binary strings use xdiff_string_bdiff()/xdiff_string_rabdiff().
