Hi, How would i read the last two line in text file,
Thank you in advance.
I’m new to PHP, so I’m sure there is a much more elegant solution that this However the script below works for me, when file.txt is the text file you want to read the last two lines from.
<?php
$file = "./file.txt";
$num_lines = 0;
$fp = fopen($file, "r");
while(!feof($fp)) {
$line = fgets($fp, 1024);
$num_lines++;
} // while
define("TOTAL_LINES", $num_lines);
$num_lines = 0;
fclose($fp);
$fp = fopen($file, "r");
while(!feof($fp)) {
$line = fgets($fp, 1024);
$num_lines++;
if($num_lines == (TOTAL_LINES-1) || $num_lines == TOTAL_LINES) {
echo $line . "<br />";
} // if
} // while
fclose($fp);
?>
He felgal Thank you it’s working 
What about last line ??
Thank you in advance.
You’re welcome jemz. The version below will output the last line only;
<?php
$file = "./file.txt";
$num_lines = 0;
$fp = fopen($file, "r");
while(!feof($fp)) {
$line = fgets($fp, 1024);
$num_lines++;
} // while
define("TOTAL_LINES", $num_lines);
$num_lines = 0;
fclose($fp);
$fp = fopen($file, "r");
while(!feof($fp)) {
$line = fgets($fp, 1024);
$num_lines++;
if($num_lines == TOTAL_LINES) {
echo $line . "<br />";
} // if
} // while
fclose($fp);
?>
Thank you so much it works again.
Hi jemz,
This will output the last line of a file:
$lines = file('test.txt');
$lastLine = array_pop($lines);
echo $lastLine;
but will load the whole file into memory, which for a multi-megabyte log file, probably isn’t what you want.
If you are on a Linux/Unix box, this is a nicer way:
echo system('tail -n 1 test.txt');

Thank you Pullo
Thanks Pullo, I knew someone would have a more elegant solution than mine, but I wasn’t expecting it to be quite so elegant
I’m assuming that happens, when you create the array with file() ?
Thanks
Yup. That’s right.
The file() function reads an entire file into an array, which is allocated memory accordingly.
