Increase the performance of yii2 project Recently, I was working on yii2 project with php 7.2 ,we were facing an issue on yii2 schema database ,in which we were using it yii2 as layer and was calling another yii2 API .At long run we were able to find that YII2 as some default rules in schema. Points: 1)  By default we are using active record ORM by YII2, So by default yii2 scans the database schema for every SQL query action. 2)To avoid it we used yii2 schema caching along with that ,we create CRON job to executes code from below link. https://forum.yiiframework.com/t/how-to-clear-schema-cache/35109/6 3) The CRON will refresh the schema of all tables and clear the cache. Please share your comments ,if there any other way to increase the performance of yii2. REFERAL: https://www.yiiframework.com/doc/guide/2.0/en/tutorial-performance-tuning#enable-schema-caching

Recently i was working on YII2 project in which i came across arrayhelper::map() and was thinking alternate in php. so i used array_map() also tested the performance of both in yii2 by start time and end time for both ,surprising was that execution time remain same.please let me know if there is any alternate that will execute faster then arrayhelper::map(). Adding the code in yii2: function find_field($value){ $value['id'] = $value['name']; return $value['id']; } $array = ['1'=>['id'=>1,'name' =>"pramodh",'address' =>'45 vk street','loc'=>'cbe'],'2'=>['id'=>2,'name' =>"pramodh kumar",'address' =>'45343 vk street','loc'=>'pune']]; $a = array_map(array($this,'find_field'),$array); print_r($a); yii2 code: $list = ArrayHelper::map($array,  ' id ' ,
