php - Loop using session -


count value changes on every refresh.

how store count value in variable , use in "for loop" on here $x <= 10;

<?php   echo "<div class='p_list_heading'> product name </div>";   echo "<div class='p_list_heading'> product price </div>";   echo "<div class='p_list_heading'> product quantity </div>";   echo count($_session['product_name']);     ($x = 0; $x <= 10; $x++) {       if($_session['product_name'][$x]!==""){          echo "<div class=\"c_hold\">";         echo "<div>".@$_session['product_name'][$x]."</div>";         echo "<div>".@$_session['product_price'][$x]."rs". "</div>";         echo "</div>";                                             }     }     ?>

store in variable $y

$y = count($_session['product_name']); ($x = 0; $x <= $y; $x++) {     if($_session['product_name'][$x]!==""){         echo "<div class=\"c_hold\">";         echo "<div>".@$_session['product_name'][$x]."</div>";         echo "<div>".@$_session['product_price'][$x]."rs". "</div>";         echo "</div>";     } }

instead of storing in variable, can do:

for ($x = 0; $x <= count($_session['product_name']); $x++) {     if($_session['product_name'][$x]!==""){         echo "<div class=\"c_hold\">";         echo "<div>".@$_session['product_name'][$x]."</div>";         echo "<div>".@$_session['product_price'][$x]."rs". "</div>";         echo "</div>";     } }
