如何将键值对存储在.csv文件中,然后将它们作为关联数组检索?

When I apply the following piece of code for a .csv file containing contents: WaterMelon,BlueBerry,BlackBerry, I get the output: Array ( [0] => WaterMelon, [1]=>BlueBerry, [2]=>BlackBerry )

The output I have got is a simple array, because I had stored simple values into the .csv file.

QUESTION:-

But what if I want to store key-value pairs in a .csv file, and then get the output like: Array ( [FruitOne] => WaterMelon, [FruitTwo]=>BlueBerry, [FruitThree]=>BlackBerry ) How can I do that?

while (($line = fgetcsv($file)) !== FALSE) {
  //$line is an array of the csv elements
  print_r($line); //check. print_r() returns an array in human readable form.
}

fclose($file);

    A CSV file can and many times does have a header row. So you could use this to read the first line and then use array_combine:

    $headers = fgetcsv($file);
    while (($line = fgetcsv($file)) !== FALSE) {
        print_r(array_combine($headers, $line));
    }
    

    Use the same concept when creating the CSV file to add the headers.

    Alternately, just define $headers yourself and use the same loop and array_combine:

    $headers = array('FruitOne', 'FruitTwo', 'FruitThree');
