svn_diff — Recursively diffs two paths
$path1
, int $rev1
, string $path2
, int $rev2
)
Recursively diffs two paths, path1 and
path2.
Bilginize:
This is not a general-purpose diff utility. Only local files that are versioned may be diffed: other files will fail.
path1First path to diff. This can be a URL to a file/directory in an SVN repository or a local file/directory path.
Bilginize: Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the calling script's working directory, use realpath() or dirname(__FILE__).
If a local file path has only backslashes and no forward slashes, this extension will fail to find the path. Always replace all backslashes with forward slashes when using this function.
rev1
First path's revision number. Use SVN_REVISION_HEAD
to specify the most recent revision.
path2
Second path to diff. See path1 for description.
rev2
Second path's revision number. See rev1
for description.
Returns an array-list consisting of two streams: the first is the diff output
and the second contains error stream output. The streams can be
read using fread(). Returns FALSE or NULL on
error.
The diff output will, by default, be in the form of Subversion's custom unified diff format, but an » external diff engine may be used depending on Subversion's configuration.
Bu işlev DENEYSELDİR. Bu işlevin davranışı, ismi ve belgeleri PHP'nin sonraki sürümlerinde hiçbir duyuru yapılmaksızın değiştirilebilir. Bu riski göze alamayacaksanız bu işlevi kullanmayın.
Örnek 1 Basic example
This example demonstrates the basic usage of this function, and the retrieval of contents from the stream:
<?php
list($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($contents);
?>
Yukarıdaki örneğin çıktısı:
Index: http://www.example.com/svnroot/trunk/foo =================================================================== --- http://www.example.com/svnroot/trunk/foo (.../foo) (revision 23) +++ http://www.example.com/svnroot/branches/dev/foo (.../foo) (revision 27) // further diff output
Örnek 2 Diffing two revisions of a repository path
This example implements a wrapper function that allows a user to easily diff two revisions of the same item using an external repository path (the default syntax is somewhat verbose):
<?php
function svn_diff_same_item($path, $rev1, $rev2) {
return svn_diff($path, $rev1, $path, $rev2);
}
?>
Örnek 3 Portably diffing two local files
This example implements a wrapper function that portably diffs two local files, compensating for the realpath() fix and the backslashes bug:
<?php
function svn_diff_local($path1, $rev1, $path2, $rev2) {
$path1 = str_replace('\\', '/', realpath($path1));
$path2 = str_replace('\\', '/', realpath($path2));
return svn_diff($path1, $rev1, $path2, $rev2);
}
?>
