Similar to fgets() except that
fgetcsv() parses the line it reads for fields in CSV format and returns an array
containing the fields read. The optional third delimiter parameter defaults as a
comma. The optional
enclosure cannot be null, and
is limited to one character. If
enclosure is more than one character, only the first
character is used.
注: The enclosure parameter was added in PHP 4.3.0.
The handle parameter
must be a valid file pointer to a file successfully opened by
fopen(), popen(), or
fsockopen().
The length parameter
must be greater than the longest line to be found in the CSV
file (allowing for trailing line-end characters).
fgetcsv() returns FALSE on error, including end of
file.
注: A blank line in a CSV file will be returned as an array comprising a single null field, and will not be treated as an error.
