Topic: Here Is One For You

[jaymc]

Right, I'll drop you straight in it. I have about 2000 .txt files that look like the below code

Code: [Select]

<?
$music = $_GET['send'];

if (strpos($music, "2diealbum1"))  {
$song = "2diealbum/songs/2diealbum/2diealbum1.wma";
$songdisplay = "2die4 - Paranoid Entity";
}

else if (strpos($music, "2diealbum2"))  {
$song = "2diealbum/songs/2diealbum/2diealbum2.wma";
$songdisplay = "2die4 - Hell On Earth";
}

else if (strpos($music, "2diealbum3"))  {
$song = "2diealbum/songs/2diealbum/2diealbum3.wma";
$songdisplay = "2die4 - Im Ok";
}

else if (strpos($music, "2diealbum4"))  {
$song = "2diealbum/songs/2diealbum/2diealbum4.wma";
$songdisplay = "2die4 - Reminissin";

I am going to create a script that will loop and read in the entire contents of each .txt file

Then, I need to dig out the following information from each else if. Ive put the information I need in BOLD

else if (strpos($music, "2diealbumi"))  {
$song = "2diealbum/songs/2diealbum/2diealbumi.wma";
$songdisplay = "2die4 - It Aint Easy";
}

What is the best way to do this. Its a bit messy but how would you do it?

P.S, its not the loop on stuck with, its the handling of the data

[businessman332211]

file_get_contents()
or fopen or something similar
then use regular expressions for whatever you need,.

[jaymc]

Can you give me an example of how to use regular expressions with what I need

[Orio]

I would recommened you to use strstr() and substr() since the lengthes of the code parts are the same all the time. That will replace regular expressions.

Orio.

[jaymc]

So the only real feasable approach is probably to explode by lines and use strstr()

[roopurt18]

if (strpos($music, "2diealbum1"))  {
$song = "2diealbum/songs/2diealbum/2diealbum1.wma";
$songdisplay = "2die4 - Paranoid Entity";
}

If it's garaunteed that the data you need is always enclosed in double quotes and that it always appears in that order, you can follow this algorithm:

1) Open file
2) Using a regular expression, fill an array with all data enclosed in double quotes only
3) With the array
  a) Starting at index 0, every third element comes from the line containing strpos
  b) Starting at index 1, every third element comes from the line containing $song =
  c) Starting at index 2, every third element comes from the line containing $songdisplay =

All it takes is for one body of the if / else if construct to assign variables out of order to ruin that approach though.
