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

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

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, "[b]2diealbumi[/b]"))  {
$song = "[b]2diealbum/songs/2diealbum/2diealbumi.wma[/b]";
$songdisplay = "[b]2die4 - It Aint Easy[/b]";
}

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

[Ninjakreborn]

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 [b]always[/b] enclosed in double quotes and that it [b]always[/b] 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 [b]strpos[/b]
  b) Starting at index 1, every third element comes from the line containing [b]$song =[/b]
  c) Starting at index 2, every third element comes from the line containing [b]$songdisplay =[/b]

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