SplFileObject::fgetcsv — Gets line from file and parse as CSV fields
$separator
= ",", string $enclosure
= "\"", string $escape
= "\\"): array|falseGets a line from the file which is in CSV format and returns an array containing the fields read.
Зауваження: The locale settings are taken into account by this function. For example, data encoded in certain one-byte encodings may be parsed incorrectly if
LC_CTYPE
isen_US.UTF-8
.
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
enclosure
character is escaped inside a field by doubling it; however, theescape
character can be used as an alternative. So for the default parameter values""
and\"
have the same meaning. Other than allowing to escape theenclosure
character theescape
character 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().
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.
Returns an indexed array containing the fields read, or false
on error.
Зауваження:
A blank line in a CSV file will be returned as an array comprising a single
null
field unless usingSplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE
, in which case empty lines are skipped.
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.
