The fputcsv Function
The fputcsv function formats the passed array into a CSV string and writes it to the specified file. The first parameter is a file pointer, the second is an array of data to write. The third parameter can specify the field delimiter (comma by default), the fourth - the string enclosure (double quotes by default).
Syntax
fputcsv(
resource $handle,
array $fields,
string $delimiter = ",",
string $enclosure = '"',
string $escape_char = "\"
);
Example
Let's write an array to a CSV file:
<?php
$file = fopen('data.csv', 'w');
$data = ['a', 'b', 'c', 'd', 'e'];
fputcsv($file, $data);
fclose($file);
?>
Contents of the file data.csv:
"a","b","c","d","e"
Example
Let's write several lines to a CSV file using a semicolon as a delimiter:
<?php
$file = fopen('data.csv', 'w');
$data1 = [1, 2, 3, 4, 5];
$data2 = ['x', 'y', 'z'];
fputcsv($file, $data1, ';');
fputcsv($file, $data2, ';');
fclose($file);
?>
Contents of the file data.csv:
"1";"2";"3";"4";"5"
"x";"y";"z"
Example
Let's write an array with data containing commas:
<?php
$file = fopen('data.csv', 'w');
$data = ['John, Doe', 'johndoe@example.com', 'New York'];
fputcsv($file, $data);
fclose($file);
?>
Contents of the file data.csv:
"John, Doe","johndoe@example.com","New York"
