[PHP] Performance Comments Question
Hi all! I would like to know if comments in the code affects the performance. I know that comments are ignored by the interpreter, but it does increase the file size, so I was thinking about a possible performance hit for highly commented files. Can anyone confirm this?

Re: [PHP] Embedded player
Hi,
You can use readdir() function for list the files. Here's a sample code from
PHP Doc www.php.net/docs.
if ($handle = opendir('/path/to/files')) {
echo Handler: $handle\n;
echo Files:\n;
while (false !== ($file = readdir($handle))) {
echo $file\n;
}
I don't know how that music player works, but since it uses XML for
playlists, I think you can use readdir() then pass the results to XML.

Subject: [PHP] Embedded player
Hi. I have been wanting to do something on my site for some time and was
recently told that it could be accomplished.
I started a daily devotion on our church website a few weeks ago, so I
changed all of my files to .php and began using a MySQL database.
I have a sermons page (www.mzbc.com/sermons.php) with a table with links to
.wma sermons. When clicked in Firefox, it prompts to download. What I want
is to be able to embed a player that will stay on that page and play all of
the files in the table.
I have found a player like this at http://musicplayer.sourceforge.net/.
There is also a Windows Media style player that will do the same thing. The
problem is I either have to create each individual sermon with an embedded
player in a new page, or create a playlist. I will eventually have way to
many sermons to use a playlist. I am sure there must be some way to tell
each file in the table to open in that player, but I am not familiar yet
with programming yet. I have php for dummies which I started reading, but I
am not sure it will do what I want.
Thanks so much,
Jedidiah

Re: [PHP] Embedded player
If you are looking for compatibility then I would recommend the flash player solution. There are a *LOT* of sites that use flash so I don't think that making it a must will impact your users. I don't know which type of users will access your church site, but I'm sure that if they even use Linux, they will install the plugin, if they haven't done so. Just my 2¢ Good luck!

Re: [PHP] Drop down directory structure list box
This depends on User-Agent. Internet Explorer queries the registry (MRU values) looking for the last open directory. There's no way to do this in PHP or plain HTML (w3 compilant) and probably you will need to write an ActiveX plugin (which will sucks if you have a Linux or Firefox user); This because you can't query the registry key(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Us er Shell Folders) and store the paths. Hope this is useful.

Re: [PHP] odd behavior

Hi Olga,
Your Javascript window.open() is missing one argument, the name of the

window.open(\add.html\,\MyWindowName\,\resizable=no,width=400,height=20

Hi everyone,
I am trying to open a new window after a successful function call (I
don't want to use a href. and onclick). Here's what I have, but for
some reason, in IE the new window does not open (I have popup blockers
disabled). It opens in Mozilla, but with the wrong size. What am I doing
wrong here?
if (insert($lname, $fname, $course, $date, $media1,
$media2))
{
echo script type=\text/javascript\\n;
echo

echo /script\n\n;
}
else
echo Error adding a record.;

Depends what you mean by no value. I suggest you read

I do use if(!$var) for simple application. Only _IF_ I need to know if the
$var is defined but empty or so I would use especific functions.

Because $x could be an empty string, 0, false, null or undefined. If
that's what you need to check for then knock yourself out.

I'm in the process of writing a PHP program that is going to be called once a week via a cron job. I don't have a place to really test this hence the reason why I'm asking about it here.
