fputcsv

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

fputcsvFormat line as CSV and write to file pointer

Descrizione

fputcsv(
    resource $stream,
    array $fields,
    string $separator = ",",
    string $enclosure = "\"",
    string $escape = "\\",
    string $eol = "\n"
): int|false

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

Elenco dei parametri

stream

Il puntatore al file deve essere valido, e deve puntare ad un file aperto con successo da fopen() o fsockopen() (e non ancora chiuso da fclose()).

fields

An array of strings.

separator

The optional separator parameter sets the field delimiter (one single-byte character only).

enclosure

The optional enclosure parameter sets the field enclosure (one single-byte character only).

escape

The optional escape parameter sets the escape character (at most one single-byte character). An empty string ("") disables the proprietary escape mechanism.

eol

The optional eol parameter sets a custom End of Line sequence.

Avviso

When escape is set to anything other than an empty string ("") it can result in CSV that is not compliant with » RFC 4180 or unable to survive a roundtrip through the PHP CSV functions. The default for escape is "\\" so it is recommended to set it to the empty string explicitly. The default value will change in a future version of PHP, no earlier than PHP 9.0.

Nota:

If an enclosure character is contained in a field, it will be escaped by doubling it, unless it is immediately preceded by an escape.

Valori restituiti

Returns the length of the written string o false in caso di fallimento.

Log delle modifiche

Versione Descrizione
8.1.0 The optional eol parameter has been added.
7.4.0 The escape parameter now also accepts an empty string to disable the proprietary escape mechanism.

Example #1 fputcsv() example

<?php

$list
= array (
array(
'aaa', 'bbb', 'ccc', 'dddd'),
array(
'123', '456', '789'),
array(
'"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach (
$list as $fields) {
fputcsv($fp, $fields);
}

fclose($fp);
?>

The above example will write the following to file.csv:

aaa,bbb,ccc,dddd
123,456,789
"""aaa""","""bbb"""

Note

Nota: Se si hanno problemi con il PHP che non riconosce i fine linea leggendo file creati o ospitati su un computer Macintosh, si può abilitare l'opzione auto_detect_line_endings della configurazione di runtime.
