finding unique values in arrays

cjgdesign

To any one who can help.. Thank you ahead of time!

Here is my deal.. I am pulling variables from a database and creating an array like so:

$test[$rowarray[variable]] = $rowarray[variable];

Then, I have something like this:

foreach($test as $key => $value)

{ PERFORM SOME TASK HERE }

Now to my ? -- I have a few variables that are the same in the database, and I only want to perform the task once per entry. Is there a way I can make my foreach statement check for unique entries so that if I have two alike entries like so: Array ( [Original #503] => Original #503 ) Array ( [Original #503] => Original #503 ) , it would only perform my task once?

Again, thanks for any help!

any particular reason you can't do

$query = select distinct(fieldname) where...... //get records w/o doubles
$result
then do

while ($row = mysql_fetch_array)
{
do whatever
}

I actually had thought of that, but unfortunately, I need other data that is not the same from the database as well. I have to pull all of the data from the database and work with different portions of it. Thats why I was trying to find a way to look for and deal only with unique variables within an array.

thanks for trying to help though!

If any one can figure this out, many thanks! It has me very frusturated at the moment...

$test[$rowarray[variable]] = $rowarray[variable];

Then, I have something like this:

foreach($test as $key => $value)
{ PERFORM SOME TASK HERE }

Now to my ? -- I have a few variables that are the same in the array, and I only want to perform the task once per entry. Is there a way I can make my foreach statement check for unique entries so that if I have two alike entries like so: Array ( [Original #503] => Original #503 ) Array ( [Original #503] => Original #503 ) , it would only perform my task once?

Again, thanks for any help!

As read your question, I can't quite follow what the data structure looks like. Perhaps writing it out would help you visualize what needs to happen. It would be similar to normalizing a database. IOW, you can group things that should be grouped. An example from an online course:
/
$course['syllabus']
$course['course_code']
$course['name']
$course['unit']
$course['unit'][1]['unit_name']
$course['unit'][1]['test']
$course['unit'][1]['test'][1]['test_name']
/

If I saw your data structure, it would help 🙂
