Descrizione

public SplFileObject::fputcsv(
    array $fields,

Writes the fields array to the file as a CSV line.

Elenco dei parametri

fields

An array of values.

separator

The field delimiter (one single-byte character only). By default , or the value set by a prior call to SplFileObject::setCsvControl().

enclosure

The field enclosure character (one single-byte character only). By default " or the value set by a prior call to SplFileObject::setCsvControl().

escape

The escape character (at most one single-byte character). By default \ or the value set by a prior call to SplFileObject::setCsvControl(). An empty string ("") disables the proprietary escape mechanism.

Nota: Usually an enclosure character is escaped inside a field by doubling it; however, the escape character can be used as an alternative. So for the default parameter values "" and \" have the same meaning. Other than allowing to escape the enclosure character the escape character has no special meaning; it isn't even meant to escape itself.

Avviso

As of PHP 8.4.0, depending on the default value of escape is deprecated. It needs to be provided explicitly either positionally or by the use of Named Arguments, or by a call to SplFileObject::setCsvControl().

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.

Errori/Eccezioni

Genera un ValueError se separator o enclosure non sono lunghi un byte.

Genera un ValueError se escape non è lungo un byte o è una stringa vuota.

Example #1 SplFileObject::fputcsv() example

<?php

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

$file = new SplFileObject('file.csv', 'w');

foreach (
$list as $fields) {
$file->fputcsv($fields);
}

?>

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

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