SplFileObject::fputcsv — Write a field array as a CSV line
$fields,$separator = ",",$enclosure = "\"",$escape = "\\",$eol = "\n"
   Writes the fields array to the file
   as a CSV line.
  
fieldsAn 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.
      
Зауваження: Usually an
enclosurecharacter is escaped inside a field by doubling it; however, theescapecharacter can be used as an alternative. So for the default parameter values""and\"have the same meaning. Other than allowing to escape theenclosurecharacter theescapecharacter has no special meaning; it isn't even meant to escape itself.
        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.
     
 Якщо значенням параметра escape не є порожній рядок
 (""), то результатом може бути CSV, що не відповідає вимогам
 » RFC 4180 або не зможе оброблятись
 функціями PHP CSV. Типовим значенням параметра escape є
 "\\", але рекомендовано явно вказати порожній рядок. Типове
 значення зміниться в наступній версії PHP, та не раніше, ніж в PHP 9.0.
Зауваження:
If an
enclosurecharacter is contained in a field, it will be escaped by doubling it, unless it is immediately preceded by anescape.
   Returns the length of the written string або false в разі помилки.
  
   Throws a ValueError if
   separator or enclosure
   is not one byte long.
  
   Throws a ValueError if
   escape is not one byte long or the empty string.

Приклад #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"""
