Reading a file

[Anon]

and trying to set a couple scalars based on its content. Format of the file is a bunch of lines like:

a|b

Can't figure out how to turn these into $a and $b.

Here is my code so far:

$file = fopen($data_file, "r");
$file_contents = fread($file, filesize( $data_file ));
fclose($file);

$lines = $file_contents;
foreach ($lines as $line) {
$data = explode('|', $line);
$a = $data[0];
$b = $data[1];
}

But that gives me the error Warning: Invalid argument supplied for foreach()

Any idea how I can accomplish this? Also considered preg_split, but couldn't figure that out either.

don't knwo what you wanna do, but foreach needs a array as far as i know. so this error comes up.

this is just a hint to the error-source, but if you'll tell me (us) what exactly you want to do maybe you'll recieve more help.

Thanks,

I want to read a file with the format:

ipnumber|time
ipnumber|time
ipnumber|time

and

1) put it into an array

2) assign ipnumber and time for each line to scalars

3) if ipnumber does not match $visitor_ip & $current_time - $time < $timeout

4) add that line to a new array

• $current_time = time(); and $visitor_ip = = getenv('REMOTE_ADDR');

Okay, this at least puts all of the lines into an array correctly and prints them out. Still need to seperate them into 2 scalars for each line and then compare the values...

$data_file = "count.txt";
$timeout = "1800";
$visitor_ip = getenv('REMOTE_ADDR');
$time_now = time();

$file = fopen($data_file, "r");
$file_contents = fread($file, filesize( $data_file ));
fclose($file);

$lines = explode("\n", $file_contents);
foreach ($lines as $line) {
print "$line<br>\n";
}

Why don't u use directly file() ?

// read entire file into array
$file_content = file("myfile.txt");

// traverse the file
for ($i=0; $i<count($file_content); $i++)
{
$line = trim($file_content[$i]); // supress space around
if (strlen($line)>1) // at least 32 chars
{
$array = explode("|", $line); // split into array
if ($array!="" && is_array($array) && count($array)==2) // chekc it
{
$ip = $array[0];
$time = $array[1];
}
}
}

Here's what I've got now. Current problem is with creating or reading the $new_lines array. Can't figure out how the data is seperated. Comma? Space? Pipe? I don't know. When I count it and print out the value it returns 1. When I print the array it says Array.

<?
$data_file = "count.txt";
$timeout = "1800";
$visitor_ip = getenv('REMOTE_ADDR');
$time_now = time();

$file = fopen($data_file, "r");
$file_contents = fread($file, filesize( $data_file ));
fclose($file);

$lines = explode("\n", $file_contents);
$new_lines = array();

foreach ($lines as $line) {
$data = explode('|', $line);
$ip = $data[0];
$time = $data[1];

***** Trouble Starts Here ******

if (($ip != $visitor_ip) && (($time_now - $time) < $timeout)) {
$new_lines[] = $lines;
}

}

if ($new_lines != "") {
$new_contents = explode(",", $new_lines);
$count = count(new_lines);
print "$new_lines[1]<br>\n";
print "$count<br>\n";
}
else {
print "error";
}

$file = fopen($data_file, "w");
fwrite($file, "$file_contents"); // Want to be able to use the filtered $new_contents array here
fwrite($file, "$visitor_ip|$time_now\n");
fclose($file);
exit;
