What potential issues could arise when using the fread function in PHP to read file content?

One potential issue that could arise when using the `fread` function in PHP is that it reads a specified number of bytes from a file, which may not always align with the content you want to retrieve. To ensure that you read the entire content of a file, you should combine `fread` with `filesize` to determine the length of the file and read it in one go. 

$filename = 'example.txt';
$file = fopen($filename, 'r');
$content = fread($file, filesize($filename));
fclose($file);

echo $content;
