Question

I need to write an array to a .csv file in PHP.

Example array:

$array = array(
    "name" => "John",
    "surname" => "Doe",
    "email" => "[e-mail]"
);

By using implode(",", $array), I get a result like this:
John,Doe,[e-mail]

However, I need to also write the key of each element to the file.

The desired output is this:
name:John,surname:Doe,email:[e-mail]

How would I achieve this?

Answer 1

Try this code:

$out = $sep = '';
foreach( $array as $key => $value ) {
    $out .= $sep . $key . ':' . $value;
    $sep = ',';
}
