Re: [PHP] Editing files by line
Cool thanks, that probably will make my code execute a decent bit faster (as
the file gets larger).
But the array_search function never works for me (don't know why, I know
exactly what I'm searching for and that it is there), so I made my own
function..
//Find and return first occurance of a string ("$Find") in any line of
$LineArray
function FindKey($LineArray, $Find)
{
foreach($LineArray as $key => $value)
{
if (ereg($Find, $value))
return $key;
}
return FALSE;
} // END OF FindKey(...);
I think this combined with your code should help me a lot, thanks a ton.

That's nice, except you could start overwriting existing data.
If you're only interested in appending to the end of a file, then use
$fp = fopen('filename', 'a+');
and fputs() all you want.
But, if you want to stick stuff into the middle...
# Real process uses file(),
# but for test, set Content manually.
$Content[] = 'The start of the content array.';
$Content[] = 'Some more stuff.';
$Content[] = 'And yet more stuff.';
$Location = array_search('Some more stuff.', $Content);
$New[] = 'Why, here is some new stuff';
$Final = array_merge(
array_slice($Content, 0, $Location + 1),
$New,
array_slice($Content, 0 - (count($Content) - $Location - 1))
);
# In your process, you'll really want to insert
# implode('', $Final) into the file with fputs(),
# but, hey, this is a demonstration.
print_r($Final);

Re: [PHP] Editing files by line
That's what I was talking about :). I wish there was something built in
that would just let me append a file where I want, that would make things a
little easier. Oh well, thanks a lot for the help that makes sense (and I
think it works).

RE: [PHP] Editing files by line
I dodn't know of any single function that does what you want, but you can do
this:
$contents = file($filename); // each line has it's own array position
$contents[$line] = $newline;
$content = implode("\n", $contents);
$f = fopen($filename, "w");
fputs($f, $content);
fclose($f);
(not tested, but should work as is) some error checking would also be
good :)

Subject: [PHP] Editing files by line
I was wondering if there was a function that would allow me to "jump" to a
certain line if a file and then write from there? I'm searching php.net
without any luck :(.
Also, if there is not specific function, is there a trick that gives the
same effect (without reading the entire file line by line, then writing to
it where I need to, then replacing the file)?
Thanks in advance (hopefully :)).
