svn_diff

(PECL svn >= 0.1.0)

svn_diffRecursively diffs two paths

설명

array svn_diff ( string $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.

Warning

If 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_HEAD to specify the most recent revision.

path2

Second path to diff. See path1 for description.

rev2

Second path's revision number. See rev1 for 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)) {
  
$contents .= fread($diff8192);
}
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);
}
?>
