Php 使大型Mysqli插入更高效

我有几个大表单需要插入数据库

我现在是这样做的

$stmt = $memberMysqli->prepare("INSERT INTO questionnairebespokeexerciseplan(userid,date,naturalbodytype,framesizewrist,framesizeelbow,fitnessgoals,workpattern,sleephours,runningbarriers,workcommute,workdistance,smoke,biomechanicalissues,limitingillness,reletivesheartproblems,birthlast12months,recurringinjuries,regularmedication,pregnant,anythingelsehealth,gymmember,runoutdoors,wouldyouliketorunoutdoors,homeequipments,whattypeequipment,exercisetime,heartratemonitor,restingheartrate,actualheartrate,maxheartrate,heartratesteadyrun,heartratebreathless,trainingshoes,preferredexercisetype,exerciseclasses,classdays,bike,bikemodel,runlunchtimebeforework,clubmember,clubschedule,personaltraining,otherheartrate,foottype) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

$stmt->bind_param('ssssssssssssssssssssssssssssssssssssssssssss',
                                                $_POST['userid'],
                                        $date,
                                        $_POST['naturalbodytype'],
                                        $_POST['framesizewrist'],
                                        $_POST['framesizeelbow'],

                                        $_POST['equipment'],
                                        $_POST['besttime'],

                                        );

我在想是否有更好/更快的方法

目前，创建此语句需要一点时间，在出现问题时对其进行调试也同样耗时。

您可以自己编写一个脚本，自动生成此语句。确保表单和数据库中的字段名保持一致，这样一段代码可能适合您：

// ADD ALL YOUR FIELDS TO THIS ARRAY. 
// THIS SHOULD BE THE ONLY PART OF THE CODE 
// WHICH YOU WILL HAVE TO MAINTAIN.

$fields = array(
'userid',
'date',
'naturalbodytype',
'framesizewrist' //etc. add all your fields
);

//you may have to adjust some fields manually:

$_POST['date'] = $date;


//HERE IS WHERE THE AUTOMATED PART STARTS
//YOU WONT EVER HAVE TO TOUCH THIS PART

//writing all fields for the query
$all_fields = implode(', ' $fields); 

//writing the correct number of questionmarks    
$questionmarks = str_repeat('?, ' count($fields)-1).'?';

//generate your statement
$stmt = $memberMysqli->prepare(
"INSERT INTO questionnairebespokeexerciseplan
 ( {$all_fields} ) 
 VALUES 
 ( {$questionmarks} )");

//write the correct amount of 's' characters for parameter types
$parameter_types = str_repeat('s' count($fields));


//generate the code which will write the parameters

$all_fields_to_bind=array();

foreach($fields as $field)
{
    $all_fields_to_bind[] = "\$_POST['". $field. "']";
}

//generate the code to be evaluated
$eval_statement = '$stmt->bind_param($parameter_types,'.implode(', ', $all_fields_to_bind).');';

//evaluate (meaning execute) your dynamically generated code
eval($eval_statement);

我没有测试这个，可能仍然有一些语法错误。我也不知道它有多安全！但它应该可以工作，因为我正在对SELECT语句使用类似的语句。

可以使代码缩短3倍。尽管列出所有允许的字段是必要的

$allowed = explode(",","userid,date,naturalbodytype,framesizewrist,framesizeelbow,fitnessgoals,workpattern,sleephours,runningbarriers,workcommute,workdistance,smoke,biomechanicalissues,limitingillness,reletivesheartproblems,birthlast12months,recurringinjuries,regularmedication,pregnant,anythingelsehealth,gymmember,runoutdoors,wouldyouliketorunoutdoors,homeequipments,whattypeequipment,exercisetime,heartratemonitor,restingheartrate,actualheartrate,maxheartrate,heartratesteadyrun,heartratebreathless,trainingshoes,preferredexercisetype,exerciseclasses,classdays,bike,bikemodel,runlunchtimebeforework,clubmember,clubschedule,personaltraining,otherheartrate,foottype");

$data = $db->filterArray($_POST,$allowed);
$sql = "INSERT INTO questionnairebespokeexerciseplan SET ?u";
$db->query($sql, $data);
