dear friend...
I have written one function in php first time and i got one error called parse error in line number 7.here i m trying to remove one value from an array.but m am not able to solve it.please solve this error..below is the code.
thanks...
function extract($this)
{
if($this->parent)
{
try
{

array_splice($parent->content->,$this);//here i can be remove from parent contents array.
}
catch(){}

}
$lastChild=$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;
}

It's because you're missing "Exception $e" in your catch statement. The $e variable will then contain the Exception object, and so you'll be able to get the messages from it, and error codes, etcetera.


Incidentally, could you please prettify your pasted code in future. There's a better chance somebody will respond when they open a thread with nicely formatted and coloured code.

i have tried using Exception $e in catch block but same error is coming..

In addition to the catch block as mentioned, this line seems to be a culprit:

should it be:
Just as a note, I would discourage anyone from using $this in any other context apart from within an object.

thanks..I am corrected that one but now i m getting fatal error : cannot redeclare extract()on line number 39 that is ?>

There's already a function called extract in PHP, so you'll need to either rename it, or put it into a class (a namespace would be ideal).

Hopefully PHP's extract doesn't do the same as your extract.

Thanks..for sharing a knowledge ..one more thing I wanted to know is : in a try block i am trying to remove an index from an array using array_splice.SO,it will work properly.

If you're wanting to remove one particular index from the array, then you could use the unset construct.

Something else that I have just noticed.
Your use of a try .. catch block won't work as expected.
The reason being that array_splice doesn't throw an Exception therefore nothing will get caught.
PHP doesn't use the try catch like JavaScript does, JavaScript's try .. catch block catches errors but PHP behaves much like Java and will only catch an Exception.

You can fudge PHP to throw an exception on error/notice etc by using set_error_handler

thank..can u please tell me what changes i can do at that place so it will work to my expectation.here i wanted to remove an object from an array.contents is an array and i wanted to remove current object from the array.

Can you explain more precisely what you are trying to do? Perhaps give some examples of how you would use the function, as currently you aren't being very clear and the code is making it difficult to work out what you're even trying to do.
