    (PHP 5 >= 5.4.0, PHP 7)

    Write a field array as a CSV line

    说明

    publicSplFileObject::fputcsv(array $fields[,string $delimiter= ","[,string $enclosure= '"'[,string $escape= ""]]]): int

    Writes the$fieldsarray to the file as a CSV line.

    参数

    $fields

    An array of values.

    $delimiter

    The optional$delimiterparameter sets the field delimiter(one character only).

    $enclosure

    The optional$enclosureparameter sets the field enclosure(one character only).

    $escape

    The optional$escapeparameter sets the escape character(at most one character). An empty string("")disables the proprietary escape mechanism.

    Note:

    If an$enclosurecharacter is contained in a field, it will be escaped by doubling it, unless it is immediately preceded by an$escape_char.

    返回值

    Returns the length of the written string 或者在失败时返回FALSE.

    Returns FALSE, and does not write the CSV line to the file, if the$delimiteror$enclosureparameter is not a single character.

    错误/异常

    An E_WARNING level error is issued if the$delimiteror$enclosureparameter is not a single character.

    更新日志

    版本说明
    7.4.0 The$escapeparameter now also accepts an empty string to disable the proprietary escape mechanism.
    5.5.21, 5.6.5 Added the$escapeparameter.

    范例

    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 tofile.csv:

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