In PHP, eof is not a specific function or keyword, but an abbreviation for “End of File.” In PHP, eof is typically used to check if a file pointer has reached the end of a file.

Here is a sample code showing how to use eof to check if the file pointer has reached the end of the file in PHP.

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

while (!feof($file)) {
    $line = fgets($file);
    echo $line;
}

fclose($file);

In the example above, the feof($file) function is used to check if the file pointer has reached the end of the file. When the file pointer reaches the end of the file, the feof($file) function will return true and the loop will stop.

It is important to check if the file exists before reading it when dealing with files to prevent errors.
