XDIFF_STRING_DIFF(3) 1 XDIFF_STRING_DIFF(3)xdiff_string_diff - Make unified diff of two stringsSYNOPSIS
string xdiff_string_diff (string $old_data, string $new_data, [int $context = 3], [bool $minimal = false])
DESCRIPTION
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).
PARAMETERS
o $old_data
- First string with data. It acts as "old" data.
o $new_data
- Second string with data. It acts as "new" data.
o $context
- Indicates how many lines of context you want to include in the diff result.
o $minimal
- Set this parameter to TRUE if you want to minimalize the size of the result (can take a long time).
RETURN VALUES
Returns string with resulting diff or FALSE if an internal error happened.
EXAMPLES
Example #1
xdiff_string_diff(3) 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:
";
echo $diff;
}
?>
NOTES
Note
This function doesn't work well with binary strings. To make diff of binary strings use xdiff_string_bdiff(3)/xdiff_string_rabd-
iff(3).
