Forgive me, I'm not a programmer.

I am trying to include the last lines of a log file on a PHP page with two line breaks after each line read. Using responses from other questions, I came up with the following:

$file = "error.log"; foreach(file($file) as $line) { echo -e $line. "\n\n"; }

When I execute this on the command line using php file.php, it is displayed correctly with the line breaks, however, on a webpage, it ignores the line breaks and prints a dirty output.

I tried to use echo -e in place of echo, but that doesn't even present the dirty output, but instead throws an error:

PHP Parse error: syntax error, unexpected '$line' (T_VARIABLE), expecting ',' or ';' in /var/www/err.php on line 12

I'm assuming echo -e isn't allowed within the foreach function? What am I doing wrong and how can I achieve the desired results?

• what do you have before $file = 'error.log' ? – Vasil Rashkov Commented Nov 28, 2016 at 15:32
• @VasilShaddix The opening tag (<?php). – Ralph Commented Nov 28, 2016 at 15:35
• you have something before PHP Parse error: syntax error, unexpected '$line' (T_VARIABLE), expecting ',' or ';' in /var/www/err.php on line 12 which the php interpreter doesn't like. – Vasil Rashkov Commented Nov 28, 2016 at 15:37
• @VasilShaddix I do. It's echo -e $line. "\n\n";. The interpreter doesn't want -e as echo works fine. All I need is for the line breaks to show in the page when accessed via the browser. – Ralph Commented Nov 28, 2016 at 15:50

echo in PHP is different than the echo command line in linux. You can't pass arguments to echo in PHP like that.

try :

echo nl2br($line . PHP_EOL);

Or if you only care about the browser

echo $line . "<br>"; Share Improve this answer Follow answered Nov 28, 2016 at 15:57 ShotgunShotgun 67822 gold badges1111 silver badges2424 bronze badges 1
