[RESOLVED] array_splice

[Anon]

Is it just me or is array_splice acting like array_slice in PHP4.03?? I've hit my head for hours now wishing it was a simple typo of a missing "p".

Well if you tell us something about what your problem is we might be able to help you :-)

The problem:

$arrayOne[] = "bla one";
$arrayOne[] = "bla two";
$arrayOne[] = "bla three";
$arrayOne[] = "junk";
$arrayOne[] = "bla five";

$arrayTwo[] = "zaa four";

// 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]])

$perfectArray = array_splice($arrayOne, 3, 1, $arrayTwo);

I would expect $perfectArray to be:

$perfectArray[0] = "bla one";
$perfectArray[1] = "bla two";
$perfectArray[2] = "bla three";
$perfectArray[3] = "zaa four";
$perfectArray[4] = "bla five";

But instead I get:

$perfectArray[0] = "junk";

This is what I would expect from array_slice not array_splice. This in PHP4.03. I've have a work around but these seems a little freaky... does anyone else encounter this and if so what version of PHP? Anyone know whare to post bugs?

And what is "junk" exactly?

Hi Anon,
I got the same problem in my PHP 5.2.5 (cli) (built: Nov 8 2007 23:18:51).

php -r "$input=array('red','green','blue','yellow'); print_r(array_splice($input,2));"

It was suppose to give output array("red", "green")
instead it gives me
Array
(
[0] => blue
[1] => yellow
)

php -r "$input=array('red','green','blue','yellow'); print_r(array_splice($input,2,1));"
suppose to output Array('red','green','yellow');
but it gives Array ( [0] => blue )

I found array_splice is behaving same like array_slice in my php 🙁

If anyone has any solution without changing the version of php please let me know, or post this bug.

array_splice() returns the extracted elements as an array. Rather, you want to write:

$perfectArray = $arrayOne;
array_splice($perfectArray, 3, 1, $arrayTwo);

EDIT:
Incidentally, this thread is 7 years old or so, but I guess that since it was not resolved there is something to add to it after all.

laserlight,
Thanks for your reply, I got it.

$input=array('red','green','blue','yellow');
print_r(array_splice($input,2,1));
print_r($input); //This is what I need, Anon was also looking for this
will output
Array
(
    [0] => blue
)
Array
(
    [0] => red
    [1] => green
    [2] => yellow
)

No problem, I have marked this ancient thread as resolved.
