dear friend..

php Code:

<?php
$x=array("r","a","f","c","s");

shuffle($x);

$z=array_search("c",$x);
unset($x[$z]);
print_r($x);
?>

PHP Code:


			
/*when i try to execute this code its working perfect.You need to notice one point in the output while removing the element-*/



Array

(

    [0] => s

    [1] => a

    [2] => r

    [4] => f

) 



    [0] => s

    [1] => a

    [2] => r

    [3]=> Nothing here

    [4] => f



/*You see that there is no index-3 in the array. Not acceptable. You have done great work.so now i wanted to use this function*/



array_remove_value($arr, $value){

return array_diff($arr, array($value));

}



/*but i am unable to use it in my code..please help me how to use it.here is my code*/

php Code:

<?php
function extract1($this)
{
//if i have a parent

    if($this->parent)
    {
        try
        {     //if i can be removed from parent's contents array;
        array_splice($parent->content,$this);// here is doubt.
            }
            catch(Exception $e)
            {
                }

         }
        $lastChild=$this->lastRecursiveChild();
        $nextElement =$lastChild->next;

        if($this->previous)
         {
        $this->previous->next=$nextElement;
     }
        if($nextElement)
         {
        $nextElement->previous=$this->previous;
     }
        $this->previous=null;
        $lastChild->next = Null;
        $this->parent = Null;
        if ($this->previousSibling)
    {
        $this->previousSibling->nextSibling = $this->nextSibling;
        }
    if ($this->nextSibling)
    {
        $this->nextSibling->previousSibling = $this->previousSibling;
    }
    $this->previousSibling = $this->nextSibling = Null;
        return $this;
}
?>
