Getting all Values of the same associative key in Array

[phoenicoperu]

I have a group of data on this Associative Array with different values and possible equal keys like:

 

industry => adasdsad,

industry => helloworld,

other => almhfe321,

environment => loremipsum

 

I´m tryin to get the values in separate chunks, with the same key each. Any help on this would be really appreciated.

 

Note: This trying to not use a multidemsional array, if possible.

well you can just loop through the array and check the matching or w/e it is you're trying to do

 

foreach($your_array as $key => $value){
check if $key matches and do stuff you wanna do
}

Your assumption is incorrect.  A key in an array is unique.  If you do this:

 

$foo['mykey'] = 'Apple';
$foo['mykey'] = 'Grape';
echo $foo['mykey'];

 

What do you expect the output to be?

 

The only way you could associate multiple "things" with a key, is to use a nested array:

 

$foo['mykey'] = array('apple', 'grape', 'banana');
var_dump($foo);

$foo['mykey'] = array('fruit' => 'apple', 'entre' => 'pb&j', 'drink' => 'milk');
var_dump($foo);

 

Arrays in php are very flexible and easy to work with once you understand the syntax of how to do certain things.  If there's something you don't understand how to do, please ask.

Thank you very much for answering so fast. And yes i see your point now, sounds logic.

 

im getting from a database,  Category->various subcategories  each, that i want to save in an Array, (will have to be multidimensional as you mention)

 

But how can i add values that i'm getting of a database, to a multidimensional array through a loop like:

 

//sql stuff

myarray = new array();

 

while ($row=mysql_fetch_array($result)) { 

      myarray[] = array ( "$row['category']" => "$row['subcategory']");

} 

 

i have this... but i need something like you said, how would i do it? mmmh im thinkin....

 

while ($row=mysql_fetch_array($result)) { 

      myarray[] = array ( "$row['category']" => array ("$row['subcategory']") );

} 

 

 

??? 

wrong direction??

 

i need this array to create a view with tables, each table with title as "category" and all its "subcategories" below of that category.

You are in the right direction, but the question is: is this a nested hierarchy (tree)?  That is tricky. 

 

What is the structure of a single row you're fetching and how does $row['category'] relate to $row['subcategory']?

[phoenicoperu]

it's fetched from 3 tables with a triple joined query and i was getting only 2 columns for each fetch

 

cat->subcat

 

that's why i was having repeated keys instead of using multidimensional arrays, but i fixed it using them and php wins again =)

 

Took me a long night but i found out how to fix it, using multi arrays.

 

Thank you very much for the tips!
