Question

I am getting the values from database as an array

<?php
    foreach($this->getlist as $value){
        foreach($this->listOfdealers as $list){

?>
<tr>
    <td>
        <input type="checkbox" name="list[]" value=<?php echo $list->nList?>
            <?php if($value->nSubList==$list->nList){echo 'checked';  } ?> />
        <label for="list_32"><?php echo $list->nList?>
        </label>
    </td>
</tr>
<?php
        }
    }
?>

I just want to compare two array values and display the checkbox checked when they are equal, but here there are displaying 16 checkbox instead of four,as I am using two for loops and I dont want that.

$this->getlist is an array that is returning from database

Answer 1

use

foreach (array_expression as $key => $value)
    statement

from
foreach-manual page

so you can use the same index for getting the values

<?php
foreach($this->getlist as $index => $value)
{
$list = $this->listOfdealers[$index];
?><tr>
      <td>
          <input type="checkbox" name="list[]" value=<?php
              echo $list->nList ?> 
<?php if($value->nSubList==$list->nList){echo 'checked';  } ?> />
      <label for="list_32"><?php echo $list->nList?>
      </label>
      </td>
</tr>
<?php
}
?>
