hi friend..
I wrote one code in php where i wanted to replacing this element with one of its siblings.but in this line
$index=$this->parent->contents->array_search($replaceWith,$parent->contents);
I have facing problem in array_search,means how to use array_search so my function will work proper.below is my function please correct it as soon as possible.

<?php
function replaceWith($replaceWith)
{
//store old parent

$oldParent=$this->parent;
//get own index in parents contents array
$myIndex=$parent->contents->array_search($this);
if ( $replaceWith->parent==$this->parent)
{
//We're replacing this element with one of its siblings
$index=$this->parent->contents->array_search($replaceWith,$parent->contents);
if ($index && $index < $myIndex)
{
//Furthermore, it comes before this element. That
// means that when we extract it, the index of this
//element will change
$myIndex=$myIndex-1;
}
$oldParent->insert($myIndex,$replaceWith);
}
}
?>
thanks.

You appear to have trouble understanding basic PHP syntax. You cannot just call an "array_search" method like that, it's a global function and must be called as such. Also in PHP, functions are entirely different to object methods so there is no $this available and certainly no properties or methods on $this.
