if TXT empty echo message possible? - php

Question

Hi I have a piece of code that is able to delete each newline in a txt file. Now my question is if the txt file is empty it gives an error message that $line doesn't exist. Now i want to add a piece off code that if txt has no content it echo's a message like "no emails in the list"
<?php
$delete = #$_GET['delete'];
$textFile = file("../emaillist/emaillist.txt");
$lines = count($textFile);
if($delete != "" && $delete >! $lines || $delete === '0') {
$textFile[$delete] = "";
$fileUpdate = fopen("../emaillist/emaillist.txt", "wb");
for($a=0; $a<$lines; $a++) {
fwrite($fileUpdate, $textFile[$a]);
}
fclose($fileUpdate);
echo"<p class='accept'>Contact verwijderd!</p>";
exit;
}
foreach($textFile as $key => $val) {
$pre= "<label style='float:left;' class='tablog3a'>";
$line = #$line . $pre . $val . "</label><a style='float:right;' href =?delete=$key><img class='clickreverse' src='images/deletetodo.png'></a><br>";
}
echo $line;
?>
I allready tried:
else {
echo "no emails in the list";
}
but that gave nothing....

I can think of a few ways to check if a file is empty:
$textfile = file('text.txt');
$lines = count($textfile);
if (empty($lines))
echo 'file is empty';
Or:
if (filesize('text.txt') === 0)
echo 'file is empty';
Or, if you want to check if it is empty, not including blank lines or extra whitespace:
$textfile = trim(file_get_contents('text.txt'));
if (empty($textfile))
echo 'file is empty';
