fgetcsv — Gets line from file pointer and parse for CSV fields
$stream
,$length
= null
,$separator
= ",",$enclosure
= "\"",$escape
= "\\"Similar to fgets() except that fgetcsv() parses the line it reads for fields 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
.
stream
A valid file pointer to a file successfully opened by fopen(), popen(), or fsockopen().
length
Must be greater than the longest line (in characters) to be found in
the CSV file (allowing for trailing line-end characters). Otherwise the
line is split in chunks of length
characters,
unless the split would occur inside an enclosure.
Omitting this parameter (or setting it to 0,
or null
in PHP 8.0.0 or later) the maximum line length is not limited,
which is slightly slower.
separator
The separator
parameter sets the field separator.
It must be a single byte character.
enclosure
The enclosure
parameter sets the field enclosure character.
It must be a single byte character.
escape
The escape
parameter sets the escape character.
It must be a single byte character or the empty string.
The 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.
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 on success, або false
в разі помилки.
Зауваження:
A blank line in a CSV file will be returned as an array comprising a single null field, and will not be treated as an error.
Зауваження: Якщо виникають проблеми з розпізнаванням закінчення рядків під час читання чи створення файлів на компʼютері Macintosh, може допомогти застосування директиви auto_detect_line_endings під час виконання.
Throws a ValueError if
separator
or enclosure
is not one byte long.
Throws a ValueError if

8.4.0 |
Relying on the default value of escape is now
deprecated.

8.3.0 | An empty string is returned instead of a string with a single null byte for the last field if it contains only an unterminated enclosure. |
8.0.0 |
length is now nullable.

7.4.0 |
The escape parameter now also accepts an empty
string to disable the proprietary escape mechanism.
