stream_get_line — Gets line from stream resource up to a given delimiter
Gets a line from the given handle.
Reading ends when length bytes have been read, when
the non-empty string specified by ending is found (which is
not included in the return value), or on EOF
(whichever comes first).
This function is nearly identical to fgets() except in that it allows end of line delimiters other than the standard \n, \r, and \r\n, and does not return the delimiter itself.
streamA valid file handle.
length
The maximum number of bytes to read from the handle.
Negative values are not supported.
Zero (0) means the default socket chunk size,
i.e. 8192 bytes.
endingAn optional string delimiter.
Returns a string of up to length bytes read from the file
pointed to by stream, або false в разі помилки.
fgets is faster but stream_get_line is more useful in a tcp server scripts.when fgets reads some bytes from socket, where EOF is reached, it returns bool(false) same as stream_get_lineBUT if remote client drops connection, and server script will try to read some data with function fgets, function will return bool(false), and stream_get_line will return string(0) ""so you can detect remote client disconnection with stream_get_line, and cannot with fgetsThis function is very efficient to redirect streams. I have older scripts to compare, and recent versions of PHP are so fast, that sometimes 2 lines might get fed into one, and this happens only on PHP 8.3 and 8.4.After digging, i found that throttling a bit is the best to do to maintain retro compatibility.$line = stream_get_line($response, 1024, "\n");usleep(10000);
