fgets

fgets — Gets line from file pointer
Description
string fgets ( resource $handle [, int $length ] )

Gets a line from file pointer.
Parameters

handle

The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen() (and not yet closed by fclose()).
length

Reading ends when length - 1 bytes have been read, on a newline (which is included in the return value), or on EOF (whichever comes first). If no length is specified, it will keep reading from the stream until it reaches the end of the line.

Note: Until PHP 4.3.0, omitting it would assume 1024 as the line length. If the majority of the lines in the file are all larger than 8KB, it is more resource efficient for your script to specify the maximum line length.

Return Values

Returns a string of up to length - 1 bytes read from the file pointed to by handle.

If an error occurs, returns FALSE.
Changelog

4.3.0 fgets() is now binary safe
