爆炸函数返回结果两次

Question

我是php编程的新手，我不知道这段代码是否正确。我在那里找一些并写下这段代码。在这里我使用爆炸功能，其结果返回两次。

<?php
$SlNo = 1;
foreach ($record as $r2) { // this is for fetching all form first table
    ?>
                    <?php
    foreach ($selectdata as $r) { // this is to fetch imploded record from second table
        $test = $r->package_id;
    }

    $explode = explode(',', $test);

    foreach ($explode as $r1) {
        // echo $r1. "<br/>";

        if ($r2->package_name == $r1) {

            ?>
<div class="col-sm-4">
    <div class="checkbox">
        <input id="checkbox<?php echo $SlNo++ ; ?>" type="checkbox"
            name="package[]" value="<?php  echo $r1; ?>" checked="checked"> <label
            for="checkbox<?php echo $SlNo++ ; ?>"> <?php  echo $r1; ?></label>
    </div>
</div>

<?php
        } else {
            ?>
<div class="col-sm-4">
    <div class="checkbox">
        <input id="checkbox<?php echo $SlNo++ ; ?>" type="checkbox"
            name="package[]" value="<?php  echo $r2->package_name; ?>"> <label
            for="checkbox<?php echo $SlNo++ ; ?>"> <?php  echo $r2->package_name; ?></label>
    </div>
</div>
<?php
        }
    }
}
?>

这就是我得到结果的方式

根据上述信息，你说$selectdata作为包价值。在for循环之前爆炸它。

<?php 

foreach($selectdata as $r)
{
$t= $r->package_id; 
}

$explode =  explode(',',$t);

$SlNo=1;
foreach ($record as $r2)
{    // this is for fetching all  form first table

//echo $r1. "<br/>";

if(in_array($r2->package_name, $explode))
{

?>
<div class="col-sm-4">
  <div class="checkbox">
    <input id="checkbox<?php echo $SlNo++ ; ?>" type="checkbox" name="package[]" value="<?php  foreach ($explode as $e){ echo $e; }?>" checked="checked">
    <label for="checkbox<?php echo $SlNo++ ; ?>"> <?php echo $r2->package_name; ?></label>
  </div>
</div>

<?php
}
else
{
?>
<div class="col-sm-4">
  <div class="checkbox">
    <input id="checkbox<?php echo $SlNo++ ; ?>" type="checkbox" name="package[]" value="<?php  echo $r2->package_name; ?>">
    <label for="checkbox<?php echo $SlNo++ ; ?>"> <?php  echo $r2->package_name; ?></label>
  </div>
</div>
<?php 
}
}
?>
