'array_push' is only useful for numerically-indexed arrays. It's basically a
shortcut for getting the length of the array and putting a value in the last
available spot in an array. It treats the array like a stack.
In an associative array (or hash), the array is indexed by strings, so the
order you input them in is irrelevant (for the most part). I think in PHP
you can actually retrieve the values in the same order as you put them in,
but this does not have to be the case. Hash keys should be arbitrarily
ordered.
$input = array();
while ( list($key, $val) = each($HTTP_POST_VARS) ) {
if ( $key != "Submit" ) {
array_push($input, $val);
}
}
Instead of 'array_push', do this:
$input[$key] = $val;

[PHP] array_push but with key, value pairs
Hey all,
I was just trying to figure out something that should be quite simple
but seems to be eluding me,
consider the following:
$input = array();
while ( list($key, $val) = each($HTTP_POST_VARS) ) {
if ( $key != "Submit" ) {
array_push($input, $val);
}
}
Ok fine, I now have an associative array with a numeric index, but
hangon I wanted to push the key = value into the array. How would I do
this, I have tried a couple of things but am having some really crazy
results ;-)
What I am really trying to do is create a new array from the
HTTP_POST_VARS while excluding certain fields, like Submit or the X and
Y values from a image button.
Any ideas/suggestions are very welcomed,
Regards
Joseph,

RE: [PHP] array_push but with key, value pairs
maybe tring this ...
$input = array();
reset ($HTTP_POST_VARS);
while ( list($key, $val) = each($HTTP_POST_VARS) ) {
if ( $key != "Submit" ) {
array_push($input, $val);
}
}

Hmm, as far as I can see this will just reset the internal pointer back
to the start of the HTTP_POST_VAR array, I suppose this should be done
in case I have called 'each' on the array before, but it does not answer
my question being: I want to push the key and value into an array not
just the value. I basically need array_push functionality but with the
ablility to use your own index values.
I hope this is more clear.

RE: [PHP] array_push but with key, value pairs
what about if you assign the key to = the id (if in a data base)?
maybe like
while (list ($key, $val) = each ($id)) {
if ( $key != "Submit" ) {
array_push($input, $val);
}
}

I am not using a database for this part as I am just collecting the data
to validate. I really want to know how to create a new array in a while
loop, which contains the key and value pairs of the array passed to
each. So lets say the above code would output:
0 = value1
1 = value2
2 = value 3
4 = value4
But I want to create:
keyname1 = value1
keyname2 = value2
keyname3 = value3
keyname4 = value4
Does anyone understand what I am on about?

Joseph
