properly using the range() function

[Anon]

Im not going to pretend like I know what im
doing, im just going to cut to the chase and
ask a really basic question.

Im looking to read the first 5 lines out of
a file, im guessing I can do this with the
foreach(range()) combo, but I dont know how
to work my array into that combo.

help please?

<?php
$file = "afileofsomesort.txt";
$arrayfile = file($file);
reset($arrayfile);

//this is where im getting confused

?>

This will return the first 5 lines of the file in the variable $buffer

$file = "afileofsomesort.txt";
$fp = fopen ($file, "r");
while (!feof ($fp)) {
$buffer .= fgets($fp, filesize($file));
if ($i == 5) {
break;
} else {
$i++;
}
}
fclose ($fp);

thanks dude. 😃

is there also a way to do that with the range
command? or am I trying to use range in the
wrong context?

range() creates an array; you are trying to qualify an array, which is an entirely different thing.

sorry to keep pestering you.

I think I understand that block of code there
but what is the significance of .=

[majik-sheff]

That means "append to".
What the routine does is read a line, append it to the buffer, read another line, append it to the buffer, and so on.

incidentally,
if ($i == 5) {

should read
if ($i < 5) {

It would have returned the first 6 lines in the first version.
