$userCount ?= D(‘model‘)->count(); ???for($i = 0; $i < ceil($userCount/5000); $i++) { ???????$begin ???= $i * 5000; ???????$end ?????= ($i + 1) * 5000; ???????$userList = D(‘model‘)->field(‘key_name‘)->limit($begin, $end)->select(); ???????foreach ($userList as $value) { ???????????... ???????} ???}最后大批量的数据最好文件开头加上:
set_time_limit(0); ?????//执行时间无限
ini_set(‘memory_limit‘, ‘-1‘); ???//内存无限
php读取数据太大&运行时间长导致500Internal Server Error错误怎么解决？
