Fgetcsv (File,length,separator,enclosure)

Parameters	Description
File	Necessary. Specifies the documents to be inspected.
Length	Optional. Specifies the maximum length of the line. Must be greater than the longest line within the CVS file. This parameter is optional in PHP 5. is required prior to PHP 5. If this parameter is omitted (set to 0 in a later version of PHP 5.0.4), then there is no limit to the length, but it may affect execution efficiency.
Separator	Optional. Set the field delimiter (one character only), and the default value is a comma.
Enclosure	Optional. Sets the field wrapping character (only one character is allowed), and the default value is double quotation marks. This parameter is added in PHP 4.3.0.

Note: You can activate the Auto_detect_line_endings runtime configuration option if you encounter a line terminator for a Macintosh file that is not recognized by PHP when reading a file.

The Fgetcsv () function instance code is as follows:

<?php $file = fopen ("Contacts.csv", "R"), Print_r (Fgetcsv ($file)); Fclose ($ file);
