What function can be used to find the position of a specific string within a file in PHP?

To find the position of a specific string within a file in PHP, you can use the `strpos()` function. This function searches for the first occurrence of a string within another string and returns the position of the match. You can read the contents of the file into a string variable using `file_get_contents()` and then use `strpos()` to find the position of the desired string. 

$file_contents = file_get_contents('file.txt');
$search_string = 'specific_string';
$position = strpos($file_contents, $search_string);

if ($position !== false) {
    echo "The position of '$search_string' in the file is: $position";
} else {
    echo "String not found in the file.";
}
