svn_diff — Recursively diffs two paths
설명
$path1
, int $rev1
, string $path2
, int $rev2
)
Recursively diffs two paths, path1 and
path2.
Note:
This is not a general-purpose diff utility. Only local files that are versioned may be diffed: other files will fail.
인수
-
path1 -
First path to diff. This can be a URL to a file/directory in an SVN repository or a local file/directory path.
Note: 상대 경로는 PHP 바이너리가 있는 디렉토리를 현재 작업 디렉토리로 인식합니다. 스크립트의 작업 디렉토리를 얻으려면, realpath()나 dirname(__FILE__)을 사용하십시오.
WarningIf a local file path has only backslashes and no forward slashes, this extension will fail to find the path. Always replace all backslashes with forward slashes when using this function.
-
rev1 -
First path's revision number. Use
SVN_REVISION_HEADto specify the most recent revision. -
path2 -
Second path to diff. See
path1for description. -
rev2 -
Second path's revision number. See
rev1for description.
반환값
Returns an array-list consisting of two streams: the first is the diff output
and the second contains error stream output. The streams can be
read using fread(). Returns FALSE or NULL on
error.
The diff output will, by default, be in the form of Subversion's custom unified diff format, but an » external diff engine may be used depending on Subversion's configuration.

예제
Example #1 Basic example
This example demonstrates the basic usage of this function, and the retrieval of contents from the stream:
<?php
list($diff, $errors) = svn_diff(
'http://www.example.com/svnroot/trunk/foo', SVN_REVISION_HEAD,
'http://www.example.com/svnroot/branches/dev/foo', SVN_REVISION_HEAD
);
if (!$diff) exit;
$contents = '';
while (!feof($diff)) {
$contents .= fread($diff, 8192);
}
fclose($diff);
fclose($errors);
var_dump($contents);
?>
위 예제의 출력:
Index: http://www.example.com/svnroot/trunk/foo =================================================================== --- http://www.example.com/svnroot/trunk/foo (.../foo) (revision 23) +++ http://www.example.com/svnroot/branches/dev/foo (.../foo) (revision 27) // further diff output
Example #2 Diffing two revisions of a repository path
This example implements a wrapper function that allows a user to easily diff two revisions of the same item using an external repository path (the default syntax is somewhat verbose):
<?php
function svn_diff_same_item($path, $rev1, $rev2) {
return svn_diff($path, $rev1, $path, $rev2);
}
?>
Example #3 Portably diffing two local files
This example implements a wrapper function that portably diffs two local files, compensating for the realpath() fix and the backslashes bug:
<?php
function svn_diff_local($path1, $rev1, $path2, $rev2) {
$path1 = str_replace('\\', '/', realpath($path1));
$path2 = str_replace('\\', '/', realpath($path2));
return svn_diff($path1, $rev1, $path2, $rev2);
}
?>
