SplFileObject::setCsvControl — Set the delimiter, enclosure and escape character for CSV
$separator = ",", string $enclosure = "\"", string $escape = "\\"): voidSets the delimiter, enclosure and escape character for parsing CSV fields.
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.
In the input stream, the enclosure character
can always be escaped by doubling it inside a quoted string,
resulting in a single enclosure character
in the parsed result.
The escape character works differently:
If a sequence of escape and
enclosure characters appear in the input,
both characters will be present in the parsed result.
So for the default parameters, a CSV line like
"a""b","c\"d" will have the fields parsed as
a"b and c\"d, respectively.
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.
Не повертає значень.
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.
