How can you ensure that file_get_contents is reading the entire file and not cutting off any content in PHP?

When using file_get_contents in PHP to read a file, it's important to set the length parameter to the filesize of the file to ensure that the entire content is read. This parameter specifies the number of bytes to read from the file, so setting it to the file's size guarantees that all content is retrieved. 

$file_path = 'example.txt';
$file_content = file_get_contents($file_path, false, null, 0, filesize($file_path));
echo $file_content;
