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);
