svn_add — Schedules the addition of an item in a working directory
Adds the file, directory or symbolic link at path to the working directory. The item will be added to the repository the next time you call svn_commit() on the working copy.
Path of item to add.
Note: 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 item is directory, whether or not to recursively add all of its contents. Default is TRUE
If true, Subversion will recurse into already versioned directories in order to add unversioned files that may be hiding in those directories. Default is FALSE
如果成功则返回 TRUE，失败则返回 FALSE。
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。
Example #1 svn_add() example
In a working directory where svn status
returns:
$ svn status ? foobar.txt
...this code:
<?php
svn_add('foobar.txt');
?>
...will schedule foobar.txt for addition into the repository.
