Writing in a text file at exact line??

hawkmaster

Hello,
I have a config file (config.ini)
There are many sections, e.g.

[PaperColor]
PaperColor1=white
PaperColor2=orange
PaperColor3=pink
PaperColor4=gray
PaperColor5=cyan
PaperColor6=red
PaperColor7=yellow
PaperColor8=green
PaperColorDefault=9
PaperColor9=blue
PaperColor10=weiss

I want to add a new color value. The new value should be added behind the value
"PaperColor10=weiss", and should be;
PaperColor11=newcolor

How can I do this all?. I think I first have to read the complete file?
I do not know how I can add the new value exact at this position?
Can I do this with regular expressions?

Later I also want to delete a color value.

thanks for any tipp or code

regards

Use [man]fopen[/man] and [man]fwrite[/man] like:

<?
$handle = fopen('config.ini','a'); 

fwrite ($handle,'PaperColor11=newcolor');

fclose($handle);
?>

using 'a' places the file pointer at the end of the file as aposed to 'w' which puts it at the start.

Hi thanks for your help.
I know how I can open and write to a file, BUT
If I do it like your code, the new entry will be written everywhere or at the last line, or not?
I need something which adds the new entry exact in the same section and exact behind the last value
PaperColor10=

well im not sure what you mean by "behind the last value PaperColor10=" but using my code will put the new info after all the old info (the last line)

ok i think i know what your tryin to do now... are you tryin to write new infomation to a specified part of the file not only at the end? like anywhere you want? if so you will need to parse the entire file into an array of some sort and then Re-write the entire file.

yes I want to write at a specified part of the ini file.
There are about 10 sections in the ini file.
In the mid of the file there is the section

[OtherSections]
...

now I want to add a new color value, but it should be in the section
[PaperColor]
and behind the last line in this section
So If I want to add the new value "klar" it should be

PaperColor12=klar

so, with the "file" function I can read the complete ini file into an array. But how can I find the exact section?
