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.

Some conservatives have Coach Factory Outlet pushed that critique further, saying that Mr. Obama’s policies are too costly, often assist the wrong people Louis Vuitton Belts and could have the paradoxical effect of driving up college costs. The dispute turns not just on different Coach Factory Outlet assessments of how policies play out, but on differing philosophical views about the role of government. During Gucci Belts his time in office, Mr. Obama has sharply increased aid to low- and middle-income students, notably through the Pell Grant Coach Factory Outlet program, which grew from $14.6 billion given to 6 million students in 2008, to nearly $40 billion for Coach Factory Outlet almost 10 million students this year. His administration also made it easier to request aid, shortening the Coach Factory Online complex federal application and allowing people to transfer their financial information electronically from the Internal Coach Outlet Online Revenue Service database. But while many education experts laud his efforts, analysts of varying political Coach Outlet Online stripes have also questioned how much impact some of the president’s policies will have, noting that the prices Coach Online Outlet charged by colleges, and student borrowing, continue to climb.But behind the headlines about soaring costs, the Coach Factory Outlet Online reality is more complex and wildly uneven, because a growing number of students receive Coach Outlet Online financial aid, and only relatively high-income families pay those fast-rising sticker prices. Adjusted for Coach Factory Online inflation, the College Board calculates, the average net price changed little over the last decade at private Coach Factory Outlet schools, and rose only modestly at public ones.Defending federal spending, Arne Duncan, the secretary of Hermes Belts education, said that for more than 30 years, college prices had risen even when federal aid had not, leading him to believe Coach Factory Online there was zero correlation.

You’ve relativelyCoach Outlet recently arrived in New Delhi after living in two of Asia’s other great cities,Coach Outlet Store Online Tokyo and Hong Kong, for several years. Do these cities feel like they’re part of the same continent? Yes, and no. In terms Coach Factory Onlineof infrastructure, they couldn’t be more different. Getting regularCoach Outlet power and water at my house in New Delhi is never a sure thing, even though Coach Purse Outlet OnlineI’m paying the same rent that I paid in Tokyo and almost the same electricity prices. Both Hong Kong and Tokyo are also crowded places,Coach Factory Outlet Online but both cities are incredibly well planned and efficiently run. Efficient is not a word I would use to describe my Coach Bags Outlet Onlineday-to-day life in New Delhi. On the other hand, one thing that I think Hong Kong and New Delhi have in common isCoach Handbags Outlet a shared sense of optimism — a feeling that the best is yet to come. That’s definitely not the feeling you get in Tokyo,Coach Outlet Online or in the U.S. when I go home. It’s a big part of what I find addictive about living and working in this part of the world. You feel like you’re watching the future unfold.

Organizers said Coach Outlet Online was opportune because the battle’s 150-year anniversary is in December, and Fredericksburg Coach Factory Outlet has been preparing to mark the sesquicentennial. in the new agreement is that Coach Outlet Online revolutionary councils from 14 Syrian provinces now each have a representative, though not all live Coach Online Outlet in Syria. The hope is that will bind the coalition to those inside the country. Perhaps Coach Bags Outlet the most important body the new group is expected to form is a Revolutionary Military Council Coach Factory Online to oversee the splintered fighting organizations and to funnel both lethal and nonlethal Coach Factory Outlet military aid to the rebels. It should unite units of the Free Syrian Army, various militias Coach Outlet Store Online and brigades in each city and large groups of defectors. Before the ink was even dry on the Coach Outlet Store final draft, negotiators hoped that it would bring them the antiaircraft missiles they crave to Coach Factory Stores take on the Syrian Air Force. The United States and Britain have offered only Coach Handbags Outlet nonmilitary aid to the uprising. A similar attempt by the Syrian National Council to Coach Factory Store supervise the military never jelled. Organizers said funding was too haphazard. Eventually foreign Coach Factory Online governments like Qatar and Saudi Arabia, which are financing and arming the rebels, found Coach Factory Online their own favorite factions to deal with. Foreign leaders notably including Secretary of State Coach Outlet Hillary Rodham Clinton urged this unification largely so they could coordinate their Coach Factory Outlet efforts and aid through a group of technocrats. Once it receives international recognition, the Coach Outlet Store Online coalition is supposed to establish a temporary Coach Outlet Online military never jelled.
