SplFileObject::fgetcsv — Gets line from file and parse as CSV fields
$separator = ",", string $enclosure = "\"", string $escape = "\\"): array|false
Gets a line from the file which is in CSV format and returns an array containing the fields read.
注意:
The locale settings are taken into account by this function. If
LC_CTYPEis e.g.en_US.UTF-8, files in one-byte encodings may be read wrongly by this function.
separator
The field delimiter (one single-byte character only). Defaults as a comma or the value set using SplFileObject::setCsvControl().
enclosure
The field enclosure character (one single-byte character only). Defaults as a double quotation mark or the value set using SplFileObject::setCsvControl().
escape
The escape character (at most one single-byte character). Defaults as a backslash (\) or the value set using SplFileObject::setCsvControl().
An empty string ("") disables the proprietary escape mechanism.
注意: Usually an
enclosurecharacter is escpaped inside a field by doubling it; however, theescapecharacter can be used as an alternative. So for the default parameter values""and\"have the same meaning. Other than allowing to escape theenclosurecharacter theescapecharacter has no special meaning; it isn't even meant to escape itself.
Returns an indexed array containing the fields read, or false on error.
注意:
A blank line in a CSV file will be returned as an array comprising a single
nullfield unless usingSplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE, in which case empty lines are skipped.
| 版本 | 说明 |
|---|---|
| 7.4.0 |
The escape parameter now also accepts an empty
string to disable the proprietary escape mechanism.
