str_getcsv — Parse a CSV string into an array
$string
,$separator
= ",",$enclosure
= "\"",$escape
= "\\"Parses a string input 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
.
string
The string to parse.
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.
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.

8.4.0 |
Relying on the default value of escape is now
deprecated.
|
8.4.0 |
Now throws a ValueError if
separator , enclosure ,
or escape is invalid.
This mimics the behavior of fgetcsv() and
fputcsv().
|
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. |
7.4.0 |
The escape parameter now interprets an empty
string as signal to disable the proprietary escape mechanism. Formerly,
an empty string was treated like the default parameter value.
