Next we will introduce how to delete array elements at the end of an array. First, we need to use the PHP function array_pop ().

• The array_pop () function deletes some elements from the end of the array:

     
     
  
      
      
  <?
      
      
   
      
      
  /* First, create an array */
      
      
   
      
      
  $FruitArray=Array("Apple", "orange", "banana", "Peach", "pear ");
      
      
   
      
      
  /* Use the array_pop () function to delete an element from the end of the array */
      
      
   
      
      
  $Popped=Array_pop($ FruitArray );
      
      
   
      
      
  /* Now we display the keys and values of all elements in the deleted array on the webpage */
      
      
   
      
      
  While (list ($ key, $ value) = each ($ fruitArray )){
      
      
   
      
      
  Echo "$ key: $ value <br> ";
      
      
   
      
      
  }
      
      
   
      
      
  Echo "<br> Finally, the deleted element value is stored in the $ popped variable. its value is $ popped ";
      
      
   
      
      
  ?>
     
     

  The result is as follows:

  0: apple

  1: orange

  2: banana
