简单的php foreach循环帮助需要

Question

I have a for each loop like this

      $sn_count = 1;
      $prodfilter = "";
      foreach($prods as $prod){
        $prodfilter .= "<div class=\"product\">".$prod['product'][1]."</div>";
        $sn_count++;
      }
      echo $prodfilter;

Now my problem my "product" class displaying border even if the $prod['product'][1] not available. So i would like to test it using if statement.

If (product value available) {
$prodfilter .= "<div class=\"product\">".$prod['product'][1]."</div>";
}   

I tried like this.

if(!empty($prod['product'][1])) {
$prodfilter .= "<div class=\"product\">".$prod['product'][1]."</div>";
 }

But its not working.

Answer 1

you can try couple of things

try this for a start

if(strlen(trim($prod['product'][$sn_count]))>0) {
 $prodfilter .= "<div class=\"product\">".$prod['product'][$sn_count]."</div>";
  }

or

if(isset($prod['product'][$sn_count])) {
 $prodfilter .= "<div class=\"product\">".$prod['product'][$sn_count]."</div>";
  }
