Create CSV File with PHP

Question

I want to create a new .csv file (without opening the raw file first via fopen). So far I have tried this:

$list[] = array
(
    "Name&q         


        

Answer 1

Using fopen with w will create the file if does not exist:

$list = [
    ["Name" => "John", "Gender" => "M"],
    ["Name" => "Doe", "Gender" => "M"],
    ["Name" => "Sara", "Gender" => "F"]
];

$fp = fopen($filename, 'w');
//Write the header
fputcsv($fp, array_keys($list[0]));
//Write fields
foreach ($list as $fields) {
    fputcsv($fp, $fields);
}
fclose($fp);

If you don't like fputcsv and fopen you can use this alternative:

$list = [
    ["Name" => "John", "Gender" => "M"],
    ["Name" => "Doe", "Gender" => "M"],
    ["Name" => "Sara", "Gender" => "F"]
];

$csvArray = ["header" => implode (",", array_keys($list[0]))] + array_map(function($item) {
    return implode (",", $item);
}, $list);

file_put_contents($filename, implode ("\n", $csvArray));

I hope this will help you.

Answer 2

You can use below code

$list[]=array ("name","gender","age"); // push header here
$list[] = array("John","M","21"); // push record here

$timestamp0     = date("Y-m-d H:i:sa",time());
$datetime       = new DateTime($timestamp0);
$datetime->setTimezone(new DateTimeZone('Asia/Jakarta'));
$timestamp      = $datetime->format("Y-m-d_H-i");

$filename = __DIR__ . "/file/" . $timestamp . ".csv";

$fp = fopen($filename, 'w');
foreach ($list as $fields) {
    fputcsv($fp, $fields);
}
fclose($fp);
