RE: [PHP] Simple array question, part 2
Nope, array_shift()... is taking off the last one too
Josip sent me the solution:
$array = array_values($array);

Re: [PHP] Simple array question, part 2
Just so you know what is happening, the numbers are keys (index) for each array element, not the order number. It's the same as if you had named the elements themselves. Like this: ['zero']=>158 ['one']=>169926 ['two']=>169931 ... Or [0]=>158 [12]=>169926 [5]=>169931 ... Deleting an element won't reorder the names of the elements since php wouldn't know how.

Nope, array_pop is just deleting the last key/valuei need to reindex

You shouldn't just delete an item from an array, it is improper

Hey, I have a $data array like this: [0] => 158 [1] => 169926 [2] => 169931 [3] => 169932 [4] => 169933 then when i delete the first one ([0] => 158) it becomes like this: [1] => 169926 [2] => 169931 [3] => 169932 [4] => 169933 how do I get it to sort again from 0,1,2,3 etc? I tried sort(), ksort(),reset() etcbut it still shows as starting from 1 instead of resorting the keys starting from 0 what function should i lookup/use? If you're always taking the first element, why not use array_shift? http://us2.php.net/manual/en/function.array-shift.php array_shift() shifts the first value of the array off and returns it, shortening the array by one element and moving everything down. All numerical array keys will be modified to start counting from zero while literal keys won't be touched. If array is empty (or is not an array), NULL will be returned. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The code follows :
if (in_array($number, $data_recs)) {
$key = array_search($number, $data_recs); // Get the key
unset($data_recs[$key]); // Unset the variable

Ok, to make sure I understand you:
given an array
('apple' => 'red', 'banana' => 'yellow')
you want a function where you submit 'red' and the function returns 'apple'?
The problem is that keys have to be unique, but values don't. What should
the function return for this array?
('apple' => 'red', 'banana' => 'yellow', 'tomato' => 'red')
I can see two choices - if values are guaranteed unique, or if you only care
about the last hit, use array_flip() to transform the array, then do a
normal lookup:
$a = array_flip ($a);
$key = $a['red'];
If you want /all/ the keys, just iterate over the array:
$result = array();
$target = 'apple';
foreach ($a as $key => $val)
{
if ($target == $val)
{
$result[] = $key;
}
}

Re: [PHP] Simple Array question
I think what you want is: Then on your next page, you can just do: foreach($_POST['id'] AS $row) echo $row; Or whatever, and that way you only get what you need.

Subject: [PHP] simple array question (Am a Newbie kindly excuse.)
Greetings my PHP people.
Will do things a bit backwork code first and what i want as that seems
the
easiest way to explain
Here is the code:
");
while(list($aa1,$aa2) = each ($a1))
{
print($aa2 . ",");
}
?>
Which gives out the output:
Tesing arrays:
ryan1,
ryan1.2,
ryan2,
ryan2.1.1.1.1.1,
ryan3,
ryan3.2,
my question/problem is simply this: how do i stop the last comma from
coming? because originally instead of giving the output to the browser i
want it to "feed" it to a hidden form field, which i enter into the
database
Yeah yeah yeah, wipe the tears of laugher from your eyes and remember,
you
too were once a newbie. :-o)
This list is great and i know i will get not one answer but many, thank
you
in advance.
