separatorThe field delimiter (one single-byte character only).
enclosureThe field enclosure character (one single-byte character only).
escape
The field escape character (at most one single-byte character).
An empty string ("") disables the proprietary escape mechanism.
当 escape 被设置为非空字符串（""）时，
可能导致生成的 CSV 不符合 » RFC 4180 的要求，
或者无法通过 PHP CSV 函数的往返处理。
escape 的默认值是 "\\"，因此建议显式地将其设置为空字符串。
默认值将在未来的 PHP 版本中更改，不早于 PHP 9.0。
没有返回值。
| 版本 | 说明 |
|---|---|
| 7.4.0 |
The escape parameter now also accepts an empty
string to disable the proprietary escape mechanism.
