Are there any specific functions in PHP that can help with extracting data from a file into an associative array?
When extracting data from a file into an associative array in PHP, you can use functions like `file_get_contents()` to read the file contents, `json_decode()` to convert the data into an associative array if the file contains JSON data, and `explode()` or `str_getcsv()` to split the data into an array if it's in a specific format like CSV.
// Read the file contents
$file_contents = file_get_contents('data.txt');
// Convert JSON data into an associative array
$data_array = json_decode($file_contents, true);
// If the file contains CSV data, split it into an array
$csv_array = array_map('str_getcsv', explode("\n", $file_contents));
