You could keep a rolling buffer of the previous 3 lines as variables
(or an array, which I would personally use). Each time you get a new
line, move each previous entry down the buffer getting rid of the
oldest. Then, when you encounter a blank line, dump your buffer to the
file.
Something like (untested):
$currLine = //get line data somehow
if (strlen($currLine)==0){
//output array contents to file
unset($buffer);
} else {
$buffer[] = $currLine;
if (count($buffer)>3){
array_shift($buffer);
}
}
