How can the use of strpos() function in PHP aid in searching for specific data within a file?

The strpos() function in PHP can aid in searching for specific data within a file by returning the position of the first occurrence of a substring within a string. This function can be used to search for specific keywords, phrases, or patterns within a file and extract the relevant information. 

$file_contents = file_get_contents('example.txt');
$search_term = 'specific_data';

$position = strpos($file_contents, $search_term);

if ($position !== false) {
    echo "Found '$search_term' at position $position";
} else {
    echo "'$search_term' not found in the file";
}
