Thinkphp commonly used techniques

One, check the code running time, memory overhead

View running timeDebug::remark('begin'); -- start markDebug::remark('end'); -- end markDebug::getRangeTime('begin','end',6) -- The third parameter defaults to 4. If you think this statistical precision is not enough, you can also set it.Log::record("/index/my_api".Debug::getRangMem('begin','end',6))Check out the memory overhead:Debug::remark('begin'); -- start markDebug::remark('end'); -- end markDebug::getRangeMem('begin','end') -- statistical unit is kbhelper functiondebug('begin');// ...other code snippetsdebug('end');// ...maybe there is other code here// perform statistical intervalecho debug('begin','end').'s';echo debug('begin','end',6).'s';echo debug('begin','end','m').'kb';
