This should be simple, but I can't think of a solution right now =P

I have an array like so
array(
['something'] => ['other'] => blah
)

imagine thousands of entries like that with the "blah"s varying and "['something'] => ['other'] =>" staying the same

Here's the question: How can I figure out positioning with the array? I figured the best way to do it was to merge with another array that contains something like..

array(
[0]
[1]
[2]
...
)

so it can become like

array(
[0] => ['something'] => ['other'] => blah
[1] => ['something'] => ['other'] => meh
)

A more concrete explanation of what you are trying to do might make this easier to answer, but the short answer is, yes you can do it like this:

PHP Code:

$arr = array(
          array( 'something' => array( 'other' => 'blah' ) )
          ); 


Honestly, however, if you find yourself using that approach you may want to stop and rethink your method. Maybe using an object would be more appropriate.

Yeah you're right, I'll try a different method.

Thanks

looks like I'll need help with a new method.

How can I select out of an array values surrounding another value?

Example: 1,2,3,4,5,6,7,8,9,10 (values in an array)

Based on the user input you get the adjacent values. So lets say I choose the #8 I should then get an output of 6,7,8,9,10.

Can this be done?

Here is one way:

PHP Code:

$range = 2;
$input; //assume this variable contains the user's input
$arr; //assume this is the array

for($i = ($input - $range); $i <= ($input + $range); $i++)
{
     echo $arr[$i];
} 


if you mean a array inside of another array you need to use qoutes and brackets on it like

$a = 0,1,2,3,4,5,6,7,8,9,10,11;
$b =-1,0,1,2,3,4,5,6,7,8,9,10;

$c = $a.$b;


echo "{$c[2][6]}";
would return as a 5

Quotes and brackets are used when variables need to be parsed in a string. If all you need to do is return the value then there is no reason to use them.

$a = 0,1,2,3,4,5,6,7,8,9,10,11;
$b =-1,0,1,2,3,4,5,6,7,8,9,10;

Arrays are declared using the array( ) "function" (its actually a language construct).

PHP Code:

$a = array(1,2,3); 


$c = $a.$b;

I'm not sure what you expect this line to do. As far as I'm aware "." is not an array operator.

echo "{$c[2][6]}";

As I mentioned earlier, the quotes and brackets are not necessary. The following code will have the same effect:

PHP Code:

echo $c[2][6]; 


Strings encased in double quotes indicate that there is a variable that needs to be parsed. Brackets are used to separate variables from from the surrounding text.
