                    <div class="col-sm-6">
                    <?php 
                    $c_box1=$c_box2=$c_box3=$c_box4=$c_box5='';
                     // $chk_box_data is which is from DB

                      if($list=='2'){$c_box2='checked';}
                      if($list=='3'){$c_box3='checked';}
                      if($list=='4'){$c_box4='checked';}
                      if($list=='5'){$c_box5='checked';}
                    }
                    ?>
                      <div class="col-sm-6 checkbox"><input id="checkbox5" type="checkbox" name="test[]" value="1" <?php echo $c_box1;?>><label for="checkbox5" >check</label></div>
                      <div class="col-sm-6 checkbox"><input id="checkbox1" type="checkbox" name="test[]" value="2" <?php echo $c_box2;?>><label for="checkbox1">check</label></div>
                      <div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="3" <?php echo $c_box3;?>><label for="checkbox2">check</label></div>
                      <div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="4" <?php echo $c_box4;?>><label for="checkbox3">check</label></div>
                      <div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="5" <?php echo $c_box5;?>><label for="checkbox4">check</label></div>
                    </div>

$list=explode(',',$r->facilities); this line will give you an array. and you are treating as a string if($list=='1'){$c_box1='checked';}. That's why you are getting error — Pankaj Makwana

The return value of explode will be an array always. So after the line $list=explode(',',$r->facilities); , the $list will be an array which is then taken in the line if($list=='1'){$c_box1='checked';} as a string for comparison, that returned the error.

$list=explode(',',$r->facilities); this line will give you an array. and you are treating as a string if($list=='1'){$c_box1='checked';}. That's why you are getting error

you can use if(in_array("1", $list)){$c_box1='checked';}, if(in_array("2", $list)){$c_box2='checked';} and so on...

<?php
    $c_box1=$c_box2=$c_box3=$c_box4=$c_box5='';
    $list=explode(',',"1,3,11,12,5");
    if(in_array("1", $list)){$c_box1='checked';}
    if(in_array("2", $list)){$c_box2='checked';}
    if(in_array("3", $list)){$c_box3='checked';}
    if(in_array("4", $list)){$c_box4='checked';}
    if(in_array("5", $list)){$c_box5='checked';}
?>


<div class="col-sm-6 checkbox"><input id="checkbox5" type="checkbox" name="test[]" value="1" <?php echo $c_box1;?>><label for="checkbox5" >check</label></div>
<div class="col-sm-6 checkbox"><input id="checkbox1" type="checkbox" name="test[]" value="2" <?php echo $c_box2;?>><label for="checkbox1">check</label></div>
<div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="3" <?php echo $c_box3;?>><label for="checkbox2">check</label></div>
<div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="4" <?php echo $c_box4;?>><label for="checkbox3">check</label></div>
<div class="col-sm-6 checkbox"><input id="checkbox2" type="checkbox" name="test[]" value="5" <?php echo $c_box5;?>><label for="checkbox4">check</label></div>
