How can the length parameter in fgets() affect the output of text files in PHP?

When using fgets() in PHP, the length parameter specifies the maximum number of bytes to read from the file. If the length parameter is too small, it may truncate the output, resulting in incomplete lines being read. To ensure the entire line is read, it is important to set the length parameter to a value that is greater than the maximum line length in the file. 

$file = fopen("example.txt", "r");

while(!feof($file)) {
    $line = fgets($file, 4096); // Set length parameter to a value greater than the maximum line length
    echo $line;
}

fclose($file);
