# svn_log

(PECL svn >= 0.1.0)

svn_log — Returns the commit log messages of a repository URL

### Description

array svn_log ( string `$repos_url` [, int `$start_revision` [, int `$end_revision` [, int `$limit` [, int `$flags` ]]]] )

svn_log() returns the complete history of the item at the repository URL `repos_url` , or the history of a specific revision if `start_revision` is set. This function is equivalent to `svn log --verbose -r $start_revision $repos_url` .

Warning

For repositories with large histories, the output may be quite large (one array item for every revision of the item). This function does not support the `--limit NUM` flag, nor does it support revision ranges (`start_revision` must be an integer).

### Parameters

`repos_url`

  Repository URL of the item to retrieve log history from.

`start_revision`

  Revision number of the first log to retrieve. Use `SVN_REVISION_HEAD` to retrieve the log from the most recent revision.

`end_revision`

  Revision number of the last log to retrieve. Defaults to `start_revision` if specified or to `SVN_REVISION_INITIAL` otherwise.

`limit`

  Number of logs to retrieve.

`flags`

  Any combination of `SVN_OMIT_MESSAGES`, `SVN_DISCOVER_CHANGED_PATHS` and `SVN_STOP_ON_COPY`, defaults to `SVN_DISCOVER_CHANGED_PATHS | SVN_STOP_ON_COPY` .

### Return Values

On success, this function returns an array file listing in the format of:

    [0] => Array, ordered most recent (highest) revision first
    (
        [rev] => integer revision number
        [author] => string author name
        [msg] => string log message
        [date] => string date formatted per ISO 8601, i.e. date('c')
        [paths] => Array, describing changed files
            (
                [0] => Array
                    (
                        [action] => string letter signifying change
                        [path] =>  absolute repository path of changed file
                    )
                [1] => ...
            )
    )
    [1] => ...

> Note: The output will always be a numerically indexed array of arrays, even when there are none or only one log message(s).

The value of action is a subset of the » status output in the first column, where possible values are:

Actions
Letter | Description
--- | ---
M | Item/props was modified
A | Item was added
D | Item was deleted
R | Item was replaced

If no changes were made to the item, an empty array is returned.

### Notes

Warning

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

### Examples

Example #1 svn_log() example

`<?php
print_r( svn_log('http://www.example.com/', 23) );
?>`

The above example will output something similar to:

    Array
    (
        [0] => Array
        (
            [rev] => 23
            [author] => 'joe'
            [msg] => 'Add cheese and salami to our sandwich.'
            [date] => '2007-04-06T16:00:27-04:00'
            [paths] => Array
                (
                    [0] => Array
                        (
                            [action] => 'M'
                            [path] =>  '/sandwich.txt'
                        )
                )
        )
    )
