String replacing?

Anon

I know that ereg_replace will replace definite strings, but what if I want to kill something like this:

#EXTM3U
#EXTINF:49,Artist - Song
\Program Files\Winamp\song.mp3
#EXTINF:5,demo
\Program Files\Winamp\demo.mp3

I'm trying to pull out the #EXTINF:NUMBER and the path to the file so I can make a script that spits out any m3u playlist in html. Problem is, I don't know how to make ereg_replace accept any type of character until (and including) the comman before the song title. And, every other line after the header has got to die, as its a pathname. Anyone got any ideas as to how I could manipulate this? Still rather new ^_

Is your entire file of that format?

If so, you don't need an regexp stuff really.

Just load the file into memory using 'file()'
That will put every line of the file into an element of an array.

$aLines = file('file.txt');

Now you can loop through all the lines of the file, starting with line 2 at element 1

to print the first pair:
echo $aLines[1];
echo $aLines[2];

Now to get the data from the lines.

#EXTINF:49,Artist - Song

You can use preg_match to get the 'artist - song' part, but if you only want the complete 'artist - song' bit, s substring is a lot easier.

use strpos to find where the comma is, and then grab everything else using substr()

echo substr($sString, strpos($sString, ',')+1);

do that for every entry, and you're done.

Thanks a lot for the reply, I'll give that a shot...woulda been a pain figuring out the right functions just from the php site ^_~

"woulda been a pain figuring out the right functions just from the php site"

Not that much of a pain, you just have to know which functions are available.

That is why I recommend that you take the time to just read the function definitions in the manual:
http://www.php.net/manual/en/ref.strings.php
this pages gives you an instant overview of which functions exist and what they can do.

This will give you ideas for new approaches to problems.
