PHP foreach loop from a text file - php

Question

I'm having trouble with a foreach loop from a text file. I have a directory tree, and a list of these directories is in a text file, I want to check the tree against the list, and echo if any directories are missing.
The problem that I'm having is that I can't see an account for a new line, so if the file has 1 line, then it returns that it exists, but if the file has two line it returns the first as missing and the second as existing, even if it's the same entry twice in the file - see code below for clarification
<?php
$logFile = 'LogFile.txt';
$rootDirectory = 'C:\testdir\\';
$verificationFile = 'verificationfiles/directoryverification.txt';
$verificationContents = file($verificationFile);
$fh = fopen($logFile,'a') or die("can't open file");
$new_line = "\r\n";
foreach($verificationContents as $directoryName) {
$subDirectory = $rootDirectory.$directoryName;
echo "$subDirectory <br />";
if (file_exists($subDirectory)) {
echo "$subDirectory Exists <br />";
} else {
echo "$subDirectory Does Not Exist <br />";
$libverificationfailed = 'failed';
fwrite($fh, "$subDirectory Not Found");
fwrite($fh, $new_line);
}
}
?>
So, as an example, the root directory has 2 sub directories, subdir1 and subdir2.
directoryverification.txt
subdir1
subdir2
and the page echos
C:\testdir\subdir1
C:\testdir\subdir1 Does Not Exist
C:\testdir\subdir2
C:\testdir\subdir2 Exists
So if there is a new line after the data in the text file, the code isn't reading it correctly. I'm hoping that this makes sense and that somebody can help.

Thanks rickdenhaan,
$subDirectory = rtrim($subDirectory);
Just before the if statement sorted it.

Try this
$rootDirectory = 'C:\testdir\\';
$verificationFile = 'verificationfiles/directoryverification.txt';
$file = new \SplFileObject($verificationFile, 'r');
$file->setFlags(\SplFileObject::SKIP_EMPTY);
while ( $dirname = $file->fgets() )
{
$dirname = $rootDirectory . trim($dirname);
if ( !file_exists($dirname) )
{
echo sprintf("direcrory %s does not exist\n", $dirname);
continue;
}
echo sprintf("direcrory %s exists\n", $dirname);
}
