Array Problem - disappearing entries

[canam101]

I'm hoping this is an obvious beginner's error.

I'm reading in a flat file with three records in it. For each read, I add the record to the array. The keys are 1,2,3.

On the first read the first record is present and viewable via key = 1.
On the second read, the first record has disappeared, but the second record is viewable via key = 2.
On the third read only the third record is present on the array.

I also printed the array after the file is closed, and it shows only the third record as present.

Any ideas? Here's the script:

<?php

$filename = 'tmpmsg.txt';
$i == 0;
$fp = popen("/usr/bin/tail -$limit $filename", 'r');

while (!feof($fp) ) {
$line = fgets($fp);
$i += 1;

$arr = array($i => $line);

print_r($arr);
}

fclose($fp);
print_r($arr);
?>

It is because of the following line.

Thanks very much. Your changed script worked like a charm.


$fp = popen("/usr/bin/tail $filename", 'r'); //the tail command, are you using linux?
//Where is $limit declared?

Yes, linux. I copied that from somewhere, but when I just tried it without the $limit it worked, so the version above should be ok.


$arr[$i] = $line; //assign value to array

Thanks. It even make more intuitive sense than what I was using.
