PHP function to READ RANGE OF LINES from LARGE FILE, USING GENERATORS LOW MEMORY

Hi everyone, I am looking for a php function ( no extra classes ) , that will read a file using generators with while feof to read specified range of lines and return them in an array. I do not wish to get the file ( 100 mb ) into an array using file () because it will consume too much memory , I just want to navigate and get the specified range of lines , like : getlinerange($source,$range); $array = getlinerange('[login to view URL]','1400-2990');
