插入语句预处理语句函数及其调用

插入数据预处理语句函数

function save($tn,$data=array()){
    global $m;
	$ty = '';
	foreach($data as $k=>$v){
	    $kk[] = $k;
		$vv[] = '?';
		$dd[] = "$data['$k']";
		switch(gettype($v)){
		    case 'integer':$ty.='i';break;
			case 'string':$ty.='s';	break;
			case 'double':$ty.='d';break;
			default:$ty.='b';break;
		}
	}
	$vvv = implode(',',$dd);
	$bind = "$stmt->bind_param('$ty',$vvv);";
	$key = implode(',',$kk);
	$value = implode(',',$vv);
	$stmt = $m->prepare("insert into $tn($key) values($value)");
    eval($bind);
    $stmt->execute();
	$stmt->free_result();
}

插入数据预处理语句函数的使用

//方法一修改数据也是同样的方法只是多了一个条件
$d['sname']='你bu好';
$d['sscore']=90;
$d['sgender']='保密';
save('stu',$d);
//方法二
save('stu',array('sname'=>'好人'));
