couple of problems

[Anon]

I am new with PHP and I have couple of problems which are listed below.

1. If I have a meta tag like this: <meta name="description" content="some text"> How can read only the content (some text) into variable?

2. When I read content of some directory by using for example dir() I get list of files which are stored there, but I also get current directory (".") and parent directory (".."). How can I get list of files and directories in some directory, without current (".") and parent ("..") in that list?

3. If I have text field named "real name". When the form has been sended the name appears "real_name" in email. How can I get it appear like "real name" in email. I know I can use ereg_replace() to remove "" but if I do that all ""s would be removed.

Thanks a lot to all!

1. I'm not sure what you mean about reading META tags, to my knowledge PHP doesn't automatically parse them.

2. See Example #2 at http://www.php.net/manual/function.readdir.php

3. First of all, you should never use ereg_replace() when str_replace() will do...it's much faster. So why don't you do this?

$emailtext = str_replace("real_name", "real name, $emailtext);

1. I assume you're opening up a file or web page and want to write a script that parses out the meta description? If so, use a regular expression to search for the specific meta tag and capture the "content" part...

2. What Ricky said.

3. You shouldn't name your form elements with a space. PHP adds the "_" in because you can't have a variable name with a space in it. You might run into trouble with certain browsers or in future browsers if there are spaces in the name.
