How can I insert array data to a file?

Question

I have created two arrays and I want all the information from both to save to a .txt file. I want it to save in the format ('DATE' 'RAINFALL') inside the file. I tried many sources for help and I still can't get it to save. How can I do it? Thank you

The format inside the txt file

Code I currently have:

$rainf_array = array($rainf0, $rainf1, $rainf2, $rainf3, $rainf4, $rainf5, $rainf6 );

    $date_array = array($date0, $date1, $date2, $date3, $date4, $date5, $date6 );


   //Input value is saved to the file

   {
     $fileHandle = fopen($fileName, "w");

      fwrite($fileHandle, $date_array .'' . $rainf_array . ",\n" );


     fclose($fileHandle);
   }

You could use implode or iterate over the array and concatenate to a string... or use a CSV parser, something like php.net/manual/en/function.fputcsv.php, that would be a CSV though although maybe you can change delimiter to a space (I would use some delimiter). — user3783243

Yeah but I want inside the file's format to look like this ('Date' 'Rainfall'). How do I make it look like that? — vorandasb

You should encapsulate the values in quotes, and use a delimiter. This is going to be hard to use in the future. I'd have 'yyyy-mm-dd', '##' or 'yyyy-mm-dd', ##. — user3783243

My suggestion:

$date_array = array($date0, $date1, $date2, $date3, $date4, $date5, $date6);
$rainf_array = array($rainf0, $rainf1, $rainf2, $rainf3, $rainf4, $rainf5, $rainf6);

$combined = array_combine($date_array, $rainf_array);

foreach ($combined as $key => $value) {
  $input .= $key . ' ' . $value . "\n";
}

Then save $input into the file.

Just a quick question I didn't understand the '$combined' function? Is there anywhere I could get more clarification? Thank you

@vorandasb The array_combine function creates an array ($combined) by using one array ($date_array) for keys and another ($rainf_array) for its values. See here: php.net/manual/en/function.array-combine.php
