[PHP] convert associative array to ordinary array
Hi, i have an associative array and i want to use it as an ordinary array, is that possible? what i mean is instead of $arr['fruit'] i want to call it by its position in the array $arr[3] thanks Never miss a thing.

Anyway, in PHP there is no difference between an associative array or an ordinary array, they're both the same thing. Only one has integers as keys while the other has strings... - Tul -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] [SOLUTION] Re: [PHP] Convert an array in an object instance
Ok, I've write a function that emulates the Perl's bless one. It works
pretty well.
The idea comes to me when Rob suggest to parse the serialized data. I
think this is better -or at least faster- than parsing all serialized
data to modify object values: Just convert the object to an array,
modify whatever values you want -no matter about member visibility-, and
then convert the array again in an object.
Note that you should NEVER modify private and protected members outside
its visibility environment... well, never UNLESS you're writting your
own serialization routines indeed (that's exactly because I need to do
it ;-) )
?
function bless ( $Instance, $Class ) {
$serdata = serialize ( $Instance );
/* For an array serialized data seems to meant:
array_tag:array_count:{array_elems}
array_tag is always 'a'
array_count is the number of elements in the array
array_elems are the elemens in the array
For an object seems to meant:
object_tag:object_class_name_len:object_class_name:object_count:{object_members}
object_tag is always 'O'
object_class_name_len is the length in chars of
object_class_name string
object_class_name is a string with the name of the class
object_count is the number of object members
object_members is the object_members itself (exactly equal to
array_elems)
*/
list ($array_params, $array_elems) = explode ('{', $serdata, 2);
list ($array_tag, $array_count) = explode (':', $array_params, 3 );
$serdata = O:.strlen
($Class).:\$Class\:$array_count:{.$array_elems;
$Instance = unserialize ( $serdata );
return $Instance;
}
class TestClass {
private $One=1;
protected $Two=2;
public $Three=3;
public function sum() {
return $this-One+$this-Two+$this-Three;
}

Re: [PHP] [SOLUTION] Re: [PHP] Convert an array in an object instance
Erm... I've seen there're some aspects to perform... it fails because
the name of the members is changed during conversion to the array. It
puts the class name using '\0' (0 is a zero, not a caps 'o') character
as separator before member name in private and an '*' in protected.
It's not an unaffordable issue, because you still can modify array
values having this in account. For example, if you want to modify the
$One private member in the array, you cannot do:
$Clone['One']=5;
you should do
$Clone[\0TestClass\0One]=5;
instead.
Anyway I think it should be easily fixed (when I've time to do it, now I
must work in another thing :-| )

[PHP] Convert an array in an object instance
Hi, Is it possible to convert an array in an object instance? I can convert an object in an array as follows: $Test = new MyClass (); $TestArray = (array) $Test; Then I've an array with all members of the object $Test, but it seems that I cannot simply do: $TestObject = (MyClass) $TestArray; To recover the object in the inverse way, so... is there any manner to do this?

[PHP] Convert An Array
http://ccl.flsh.usherb.ca/db/authors_under_study.php or $names = array (john, mary, bill, mary, bill, mary, bill, john, bill, john); 1) How do I count the elements of $names to produce: bill 4 john 3 mary 3 2) How do I store the counted elements into a new array? How do I create this: $new_array = array (bill=4, john=3, mary=3) I'm looking at http://www.php.net/manual/en/function.array.php but not sure.
