查詢時呼叫函式，小於0的數，自動補零;分組時，擷取欄位分組統計

$select = [
  DB::RAW('SUBSTR(create_at,0,10) as sum_date'),
  DB::RAW("TO_CHAR(SUM(totalprice),'fm9999999990.00') as total_amount"),//小於1自動補零
  DB::RAW("TO_CHAR(SUM(fee),'fm9999999990.00') as total_fee")
];
$data = OrderTemp::select($select)->where("is_income",2)->groupBy(DB::RAW('SUBSTR(create_at,0,10)'))->get();
 

查詢結果寫入一維陣列（原本二維陣列）

$terminal = Terminal::where('is_success', '!=', '1')->select('term_id')->get()->pluck('term_id')->toArray();
格式說明:
[
    "00002001707120000001",
    "0000200301AZ7A000005",
    "0000200301AZ7A000011",
    "0000200301AZ7A000022"
]

列印完整SQL

$params = $query->getBindings();
$sql = str_replace('?', '%s', $query->toSql());
$wholeSql = sprintf($sql,...$params); // 三個點不能少
dd($wholeSql); 
 

上傳檔案基礎配置

if ($_FILES['pic']["error"] == 0){
	$path = "./Public/image/advice/".date('Ymd',time());
	$last_id = M('Advice')->order('id desc')->getField('id')+1;
	$last_id = $last_id?$last_id:1;
	if(!is_dir($path)){
		mkdir($path,0777,true);
		chmod($path,0777);      
		chown( $path,'daemon');
		chgrp( $path,'daemon');          
	}   
	$f = $path."/".time().$last_id.".png";
	if($_FILES["pic"]['name'] != ''){
	$data["pic"] = "http://".$_SERVER['HTTP_HOST'].$f;
	move_uploaded_file($_FILES["pic"]["tmp_name"],$_SERVER['DOCUMENT_ROOT'].$f);
   }
}
