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).

XDIFF_FILE_RABDIFF(3) 1 XDIFF_FILE_RABDIFF(3)xdiff_file_rabdiff - Make binary diff of two files using the Rabin's polynomial fingerprinting algorithmSYNOPSIS
bool xdiff_file_rabdiff (string $old_file, string $new_file, string $dest)
DESCRIPTION
Makes a binary diff of two files and stores the result in a patch file. The difference between this function and xdiff_file_bdiff(3) is
different algorithm used which should result in faster execution and smaller diff produced. This function works with both text and binary
files. Resulting patch file can be later applied using xdiff_file_bpatch(3)/xdiff_string_bpatch(3).
For more details about differences between algorithm used please check libxdiff website.
PARAMETERS
o $old_file
- Path to the first file. This file acts as "old" file.
o $new_file
- Path to the second file. This file acts as "new" file.
o $dest
- Path of the resulting patch file. Resulting file contains differences between "old" and "new" files. It is in binary format and
is human-unreadable.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
xdiff_file_rabdiff(3) example
The following code makes binary diff of two archives.
<?php
$old_version = 'my_script_1.0.tgz';
$new_version = 'my_script_1.1.tgz';
xdiff_file_rabdiff($old_version, $new_version, 'my_script.bdiff');
?>
NOTES
Note
Both files will be loaded into memory so ensure that your memory_limit is set high enough.

i'm trying to parse a file with lines like the below where i need to get a diff on the 169-182 so that the result is 13 for instance. I was looking into using bc but am not that familiar with embedding it in a script.

Hi,
I'm searching for unified diff viewer for Linux. Not for compare. I already have a .diff file and I need to view it side-by-side. I've tried diffuse, meld, vimdiff, kdiff3, kompare, beediff. But they compare two o more files and can not open an existing diff side-by-side (or I just didn't... (4 Replies)
Hi,
Is there a way to add padding to a diff result in unix so number of "< .." lines will be equal to number of "> .." lines?
For example, if the original result is:
9a10
> "line which exists only in one file"
The changed result would be:
9a10
< "noMatch"
---
> "line which exists... (5 Replies)
