PHP (array_splice & array_slice)

array_splice -- Remove a portion of the array and replace it with something else



array array_splice ( array input, int offset [, int length [, array replacement]]

Quote:

array_slice -- Extract a slice of the array



array array_slice ( array array, int offset [, int length])

Correct me if I'm wrong pretty please, but shouldn't this return what is located at $UserName($key)?



$UserName = array_slice($UserName, $key, 1);





Again, correct me if I'm wrong, but shouldn't this return everything BUT what is at $UserName($key)?



$UserName = array_splice($UserName, $key, 1);





It's driving me absolutly crazy, and to tell you the truth, I've used both and they both give me the same thing. NOTHING is more frustrating when things like this happen.

$UserName = array_splice($UserName, $key, 1);

Nope. The function works exactly as advertised. From the array_splice description at php.net:

Quote:

It returns an array containing the extracted elements.

Your call to array_slice returns element $key from $UserName, and array_splice extracts that element. Therefore the results you get are correct.

So if I want an array of everything but $key from the array $UserName, how would I do that?

Like this:

Code:

<?

$UserName = array("1","2","3");

$key = 1;



array_splice($UserName, $key, 1);

var_dump($UserName);

?>









array_splice extracts the specified number of elements from offset $key out of $UserName. Therefore $UserName will contain everything but the element at position $key after "splicing" the array.



var_dump is a function that spits out the contents of any given variable. In the above function it returns:

Code:

array(2) {

[0]=>

string(1) "1"

[1]=>

string(1) "3"

}

I think I'm going to cry. I swear I was doing that before and it wasn't working.



Oh well as long as it's working now. Thanks so much!
