我如何从两个表中获取数据

Question

public function queries($companyID, $entityType, $entityValue)
{
    $data = [];
    $details = DiraQuestion::where('company_id', $companyID)->where('eType', $entityType)->where('eVal', $entityValue)->get();
    $detailsAns = DiraResponses::where('company_id', $companyID)->where('eType', $entityType)->where('eVal', $entityValue)->get();

    foreach($details as $key => $detailsValue)
    {
        if(!array_key_exists($detailsValue->intent, $data))
        {
        $data[$detailsValue->intent] = [];
        }

        if(!array_key_exists($detailsValue->reply, $data[$detailsValue->intent]))
        {
            $data[$detailsValue->intent]['answer'][$detailsValue->reply] = $detailsValue->id;
        }

        if(!array_key_exists($detailsValue->queries, $data[$detailsValue->intent]))
        {
            $data[$detailsValue->intent]['question'][$detailsValue->queries] = $detailsValue->id;
        }
    }

    ksort($data);
    return view('AltHr.Chatbot.queries', compact('data','entityType','entityValue','companyID'));
}

I have written a code to view data but I'm having some problems.

From the code I wrote it's viewing the data from one table which is the $details . But I also wanna view the data from the $detailsAns .

How can I do that? also can I foreach two data from that two tables?

Answer 1

The first way use normal for instead of a foreach ,

For Exmple:

public function test(){
    $data = [];
    $details = ["details0", "details1", "details2", "details3", "details4", "details5", "details6", "details7"];
    $detailsAns = ["details0Ans", "details1Ans", "details2Ans", "details3Ans", "details4Ans", "details5Ans", "details6Ans", "details7Ans"];


    for ($i = 0 ; $i < sizeof($details) || $i < sizeof($detailsAns) ;$i++) {
        echo $details[$i];
        echo $detailsAns[$i];
    }
}   

Second way use MultipleIterator::attachIterator

Not the most efficient, but a demonstration of SPL's multipleIterator

$mi = new MultipleIterator();
$mi->attachIterator(new ArrayIterator($a));
$mi->attachIterator(new ArrayIterator($b));

$newArray = array();
foreach ( $mi as $value ) {
    list($value1, $value2) = $value;
    echo $value1 , '-' , $value2 , PHP_EOL;
}

 public function queries($companyID, $entityType, $entityValue) { $data = []; $details = DiraQuestion::where('company_id', $companyID)->where('eType', $entityType)->where('eVal', $entityValue)->get(); $detailsAns = DiraResponses::where('company_id', $companyID)->where('eType', $entityType)->where('eVal', $entityValue)->get(); $mi = new MultipleIterator(); $mi->attachIterator(new ArrayIterator($details)); $mi->attachIterator(new ArrayIterator($detailsAns)); foreach($mi as $value ) { list($detailsValue, $detailAnsValue) = $value; if(!array_key_exists($detailsValue->intent, $data)) { $data[$detailsValue->intent] = []; } if(!array_key_exists($detailsValue->reply, $data[$detailsValue->intent])) { $data[$detailsValue->intent]['answer'][$detailsValue->reply] = $detailsValue->id; } if(!array_key_exists($detailsValue->queries, $data[$detailsValue->intent])) { $data[$detailsValue->intent]['question'][$detailsValue->queries] = $detailsValue->id; } } ksort($data); return view('AltHr.Chatbot.queries', compact('data','entityType','entityValue','companyID')); } 

Example:

public function test(){
    $data = [];
    $details = ["details0", "details1", "details2", "details3", "details4", "details5", "details6", "details7"];
    $detailsAns = ["details0Ans", "details1Ans", "details2Ans", "details3Ans", "details4Ans", "details5Ans", "details6Ans", "details7Ans"];

    $mi = new MultipleIterator();
    $mi->attachIterator(new ArrayIterator($details));
    $mi->attachIterator(new ArrayIterator($detailsAns));
    foreach($mi as $value ) {

        list($detailsValue, $detailAnsValue) = $value;
        echo($detailsValue);
        echo($detailAnsValue);
    }
}
//output: details0details0Ansdetails1details1Ansdetails2details2Ansdetails3details3Ansdetails4details4Ansdetails5details5Ansdetails6details6Ansdetails7details7Ans
