Get the number of a line in a file

[phlow]

How can I find out in which line I am in a file and then later jump back to that line?
ftell(int fp) only gives me the position of the pointer and that doesn't help me.
any support is welcomed.
thanks, Phlow.

It is probably easiest to just read the whole file into an array, and manipulate it afterwards.

You can also count from the start, i.e.;

---

function flineseek($fp, $line) {
for ($x = 0; $x < $line; $x++)
$void = fgets($fp, 4096);
}

$fp = fopen($file, "r");
$line = 0;
while ($oneLine = fgets($fp, 4096)) {
$line++;
// do something with $oneLine
if (something) $savedLine = $line;
}
fclose($fp);

Now, open it again,

$fp = fopen($file, "r");
flineseek($fp, $savedLine);
// do something

fclose($fp);

.. and you're done.. (?)
