SplFileObject::fgetcsv

(PHP 5 >= 5.1.0, PHP 7)

SplFileObject::fgetcsv — Gets line from file and parse as CSV fields

说锟斤拷

public SplFileObject::fgetcsv ([ string $delimiter = "," [, string $enclosure = "\"" [, string $escape = "\\" ]]] ) : array

Gets a line from the file which is in CSV format and returns an array containing the fields read.

Note:

The locale settings are taken into account by this function. If LC_CTYPE is e.g. en_US.UTF-8, files in one-byte encodings may be read wrongly by this function.

delimiter

The field delimiter (one character only). Defaults as a comma or the value set using SplFileObject::setCsvControl().

enclosure

The field enclosure character (one character only). Defaults as a double quotation mark or the value set using SplFileObject::setCsvControl().

escape

The escape character (at most one character). Defaults as a backslash (\) or the value set using SplFileObject::setCsvControl(). An empty string ("") disables the proprietary escape mechanism.

Note: Usually an enclosure character is escpaped inside a field by doubling it; however, the escape character can be used as an alternative. So for the default parameter values "" and \" have the same meaning. Other than allowing to escape the enclosure character the escape character has no special meaning; it isn't even meant to escape itself.

Returns an indexed array containing the fields read, or FALSE on error.

Note:

A blank line in a CSV file will be returned as an array comprising a single NULL field unless using SplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE, in which case empty lines are skipped.
