fgetcsv
(PHP 4, PHP 5)
fgetcsv — Gets line from file pointer and parse for CSV fields
說明
Similar to fgets() except that fgetcsv() parses the line it reads for fields in CSV format and returns an array containing the fields read.
參數
- handle
-
A valid file pointer to a file successfully opened by fopen(), popen(), or fsockopen().
- length
-
Must be greater than the longest line (in characters) to be found in the CSV file (allowing for trailing line-end characters). It became optional in PHP 5. Omitting this parameter (or setting it to 0 in PHP 5.0.4 and later) the maximum line length is not limited, which is slightly slower.
- delimiter
-
Set the field delimiter (one character only). Defaults as a comma.
- enclosure
-
Set the field enclosure character (one character only). Defaults as a double quotation mark.
- escape
-
Set the escape character (one character only). Defaults as a backslash (\)
Return值
Returns an indexed array containing the fields read.
Note: 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.
Note: 如果碰到 PHP 在讀取文件時不能識別 Macintosh 文件的換行字元,可以開啟 auto_detect_line_endings 執行時期設定選項。
fgetcsv() returns FALSE on error, including end of file.

註釋
Note: Locale setting is taken into account by this function. If LANG is e.g. en_US.UTF-8, files in one-byte encoding are read wrong by this function.
