Hi all,

I've a problem thats been bothering me for a week now

I have an array $animals

keys and values like this

1 => cat
2 => dog
3 => mouse
4 => horse

I want to be able to access them using either a key or a pointer, however
the key/pointer will be a variable

without variables, if I want dog, I can either use $animals[1] or
$animals['2']

but with a variable , eg. $x = 2
$animals[$x] will always give me 'mouse'

what syntax do I need to use for $animals[$x] to give me 'dog' when $x=2 ?

I've tried all manner of apostrophes and escaped apostrophes, but no luck.
Can anyone help me
Thanks for your time!

Array

    [2] => dog
    [3] => mouse
    [4] => horse
)
dog

source:
<?
$animals=array(1=>'cat',2=>'dog',3=>'mouse',4=>'horse');
print_r($animals);
$x=2;
echo $animals[$x]."\n";

I would think that you have string keys instead of integer ones. Perhaps
there is some whitespace in the variable using to set the key?

For example:

$array = array(' 2' => 'dog'); // there is a whitespace before the number 2

will set the element of ordinal number 0 and key ' 2' to 'dog'. To get
that value you would either ask for $array[0] or $array[' 2'].

Doing a print_r() or var_dump() on the array will let you know what the
actual contents of both the keys and values are.

don't hijack an existing thread. (i.e.

asking a new question.

you need to learn to use var_dump(), and if you look at
the line of code below you should have everything you need
to know about numeric array keys:

$a = array(2 => "foo"); $b = array("2" => "foo"); var_dump($a, $b, ($a === $b));

thanks for all the comments so far, i'm not sure you are understanding what
I am asking for.
My problem is NOT knowing what is in the arrays, but how to access them.

My ordial number/key is a variable, and I need to sometimes use it as a key,
and sometimes as an ordial

so I need 2 ways of writing $array[$x],

one being equivalent to $array[0] - $x is treated as an integer
and one being equivalentt to $array['0'] - $x is treated as a string

so far I can only get it to work as an ordial number not a string. Any
attempt at apostrophes around $x brings up an error

Any ideas?

$array['0'] and $array[0] are identical in PHP. The string '0' will be
automatically juggled to an integer when used as an index. You CANNOT
differentiate even if you want.

You probably didn't install PHP correctly.

Hi,

I have a page with a form on it which posts to itself. The problem is when
someone refreshes the page it enters the data into the DB again. How do I
clear these variables so that doesn't happen. I tried the unset function,
but no luck. I really don't want to use sessions or cookies as this is just
a simple little page, but still, it has to work right.

Thanks

Use the header function (http://php.net/header) to redirect to the same
page. The POST vars are coming from the client, so you can't get rid of
them by unsetting them. By redirecting you are giving the browser a new
page which is then what will be retrieved if the user refreshes it,
rather than refreshing the POSTed request.

I'm working on a project where we'd want partner sites to get our
content on the other web sites.
A key priority is that they won't have much technical sophistication
(probably no db experience or php experience).
Also, these would be third party sites so there would also be an
issue of requirements (differnet xsl processors,
no allow_url_fopen, etc...)

I tried looking at sites that get their content on other sites to see
how they do it:

the possible solutions seem to be:
1. rss / xml - this is "well known" but would have a pretty high
technical hurdles on the other sites. We could create
every walk through and code sample but I still think it would be too
involved. Only way out is either a xsl transformation (not
going to happen), custom parsing library in php (maybe) or writing to
db with associated libraries (too complex)
2. serialized php with custom library - this seems more feasible than
#1 in terms of requirements
3. php proxy and ajax call / json - i think this would be too complex
and would require too much manipulation of apache to handle
subdomains, etc.....
4. included javascript - kinda how digg handles syndication (see
http://www.digg.com/add-digg for example).
This would seem to be the lowest barrier to entry. The main concern
is preventing unauthorized bots from crawling. It would seem
our only option would be using the referer property but this could be
forged relatively easily.
5. SOAP - no way
6. REST - if meant to just mean xml, i see this as an extension of #1.

any thoughts or opinions would be appreciated.
