PHP 4, PHP 5, PHP 7, PHP 8
fgets - Gets line from file pointer
Manual
Code Examples

fgets( resource$stream, [int|null$length = null] ): string|false

Gets a line from file pointer.

Parameters

stream

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, or a newline (which is included in the return value), or an EOF (whichever comes first). If no length is specified, it will keep reading from the stream until it reaches the end of the line.

Return Values

Returns a string of up to length - 1 bytes read from the file pointed to by stream. If there is no more data to read in the file pointer, then false is returned.

If an error occurs, false is returned.

Notes

Note:

If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem.

Note:

People used to the 'C' semantics of fgets should note the difference in how EOF is returned.
