[Resolved] foreach help

[odv_fish]

I have a few different fields that I need to combine together after the form is posted.

Fieldnames are as follows:

camps[camp_notes][field1]
camps[camp_notes][field2]

Code:

foreach ($camps['camp_notes'] as $key => $value)
     {
     $camps['camp_notes'] .= $key.': '.$value."\n";
     unset($camps['camp_notes'][$key]);
     }

Output I am receiving...

Arraygrade: 12 age: 21 years_experience: 10

I thought by unsetting the sub-array, it would no longer be an array? I need to get rid of the word 'Array'.

Can you post the code that your using to display your output?

[odv_fish]

echo $camps['camp_notes'];

There must be some array residue left over even though your unsetting the $key part of it. Why don't you just build a new variable, rahter than reusing the one you have:

foreach ($camps['camp_notes'] as $key => $value) 
                                            { 
                                            $output .= $key.': '.$value."\n"; 
                                            }
echo $output;

I could, but it doesn't really answer my question 😉

The other reason is because I'm using multi-dimensional arrays to logically parse variables for storing the data into the database. So to use another variable would defeat the purpose.

So... is there an easy way to flush the variable of the "empty" array?

[odv_fish]

Ok. I used an $output variable to store the info, unset the $camps['camp_notes'] variable altogether, then re-issued it with the $output variable.

If there is a better way to go about doing this, please feel free to chime in.
