Read next line in file - Skillet` - 08.10.2012

Hello,
How do I read from a file the next line from a file ?
for example :
File:
Код:
1#
Text 1
2#
Text 2
3#
Text 3
4#
Target text - This is my text ^.^
5#
Text 5
Now if I want to find number "4#" and read the text under that line and use it in the script,how do I do this without using any include ?

Did you try to look at this page already?; https://sampwiki.blast.hk/wiki/Fread

Re: Read next line in file - Riddick94 - 08.10.2012

Which system do you using to save/load files.

So I assume he isn't using any "systems"

He need to use atleast an a_samp include.. Alright, just kidding now. Well, the solution is obvious and ready on Wiki.

Re: Read next line in file - Kwarde - 08.10.2012

Well, I'm not sure if the solution is THAT obvious. Because this guy over here is asking to find something in the file by searching for "4#", and the fread (on the SA:MP Wiki) only shows how to read line-by-line. However, it still should be easy ;p

Re: Read next line in file - ReneG - 08.10.2012

There is currently no function to specify which lines to search by, but this may work.
PHP код:
stock readfile()
{
    new 
        File:file = fopen("file.txt", io_read),
        string[128],
        foundline = 0;
    
    while(fread(file, string, sizeof(string)) {
        if((strfind(string, "#4") != -1) && !foundline) {
            foundline = 1;
            continue;
        }
        
        if(foundline) {
            printf("%s", string);
        }
    }
    return 1;
} 
Very impractical though.

No,actually the point was to direct the pawn to the line I want to extract and pack it into a string without searching for a string.
