PHP fputcsv() Function

The PHP fputcsv() function formats a line (passed as a fields array) as CSV and writes it (terminated by a newline) to the specified file stream.

Syntax

fputcsv(stream, fields, separator, enclosure, escape, eol)

Parameters

`stream`	`Required.` Specify a valid file pointer to a file successfully opened by or fsockopen() (and not yet closed by fclose()).
`fields`	`Required.` Specify an array of strings.
`separator`	`Optional.` Specify the field delimiter (one single-byte character only). Default is comma ( , )
`enclosure`	`Optional.` Specify the field enclosure character (one single-byte character only). Default is ".
`escape`	`Optional.` Specify the field escape character (at most one single-byte character). Default is backslash (\). An empty string ("") disables the proprietary escape mechanism.
`eol`	`Optional.` Specify the custom End of Line sequence. Default is backslash (\n).

Return Value

  array(1,'John',25,3000),
  array(2,'Marry',24,2750),
  array(3,'Jo',27,2800)
);

//opening the CSV file in write mode
$fp = fopen("data.csv", "w");

//formats $list as CSV and writes 
//it to the CSV stream
foreach ($list as $fields) {
  fputcsv($fp, $fields);
}
