A small example of replacing array key names in PHP

/**
* @todo Optimize EXCEL table output for YII query output with database table field names and key names
* @todo Replace key names with 0, 1, 2...
* @param array $data
* @return array( 'excel_title'=array(),'excel_ceils'=array());
*/
public function excelDataFormat($data){
for ($i=0;$i$ each_arr=$data[$i];
$new_arr[]=array_values($each_arr); //Return all key values ​​
}
$new_key[]=array_keys($data[0]); //Return all index values
return array('excel_title'=>$new_key[0],'excel_ceils'=>$new_arr);
}

The author wrote this method purely to handle EXCEL export , if it is often used in the project, you can change the name!
