How can I remove the last line of a file using php?

Question

I\'ve tried a lot of potential solutions, but none of them are working for me. The simplest one:

$file = file(\'list.html\');
array_pop($file);

Answer 1

Remove first and last line of a variable in PHP:

Using phpsh interactive shell:

php> $test = "line one\nline two\nline three\nline four";

php> $test = substr($test, (strpos($test, "\n")+1));

php> $test = substr($test, 0, strrpos($test, "\n"));

php> print $test;
line two
line three

You might have meant "The last non blank line". In that case do this:

Notice that there are three blank lines after the content. This gets rid of those lines before removing the last:

php> $test = "line one\nline two\nline three\nline four\n\n\n";

php> $test = substr($test, 0, strrpos(trim($test), "\n"));

php> print $test;
line one
line two
line three
