RE: [PHP] replacing a line in a file
the point is that you can't replace part of a flat file. you can append to
the content or replace it all. if you want to replace part, you need to read
it all, amend the relevant line and then replace it all.

having problems replacing a line in a file.
need to search the whole document for a string and then
replace that line
with a string.
any ideas?
this is causing lots of problems now.
$fpoint3 = fopen ($testshadow, "r+") or die("couldnt open
shadow file
again");
$contents = fread ($fpoint3, $shadowfilesize);
fputs ($fpoint3, ereg_replace("$data[0]:$shadow[1]",
"$data[0]:$data[1]",
$contents));
fclose ($fpoint3);
any ideas?

Re: [PHP] replacing a line in a file
Hey!
I didn't try to analyze your code, but why not using the file() function
which opens a file and puts it's content into an array.
After doing that, you could seek that array line-by-line for
"$data[0]:$shadow[1]"
and replace it with $data[0]:$data[1].
Since you're dealing with full lines in your script, file() is the best
choice (though,
sometimes not the fastest).
It will also improve your code by making it much easier to read than when
using
fopen(), fread(), etc.. as you're doing now.
