svn checkout is not working with php exec()

I want to checkout some files from svn to my locale folder using php. For that I write this code.

    $checkout = "svn --username myuname--password mypass checkout svn://192.16.20.125/projname/trunk/content/Poems/files.swf  D:/PHP_Projects/MyTempRelease/content/Poems/files.swf";    
    exec($check开发者_开发问答out);

But its not checkout file to my locale. Not return any error.

I'd try this with a client - Tortoise or something else. Just to see if it works.

I'd also wonder if the lack of a space between "myuname" and "--password" is killing you.

I think it's because you are missing a space between your username and --password.

Try running the command directly (on the command line) and verify that it is working.
