the issue you're keeping big excel object in memory, , script runs out of usable memory.

first should seek determine if there ways cut down memory consumption of script, if fails need increment php memory limit. in php.ini file, locate memory_limit setting determines maximum amount of memory script may consume, e.g.

memory_limit = 64m;

increase value until no longer see error.
