I have a foreach loop and need to dynamically create the key value pairs and build the array.  
After running the foreach loop, it should produce something like

  $sampleArray = array(
      'firstfield' => (string)"Person",
     'thirdfield' => (integer)'Quantity',
     'fourthfield' => (string)'Product'
  );

Open in new window


I need to know how to use foreach loop and build the sample array like above

Not sure what you mean - you need something to loop through with the foreach loop (such as an array)

What exactly do you want to run the foreach loop on?

Hi Chris

I have values coming from a database table and I need to save these into another table.  

 I have a foreach loop which iterates through.  I want to merge these so it looks like the sample below.  I had problems with each (key value pair replacing, rather than combining them into one array  

       foreach($test as $k=>$sampleEntry)
      {

the key value pair was in here  
      }
      

The goal is to combine the ones from the loop into one array like below.  

$sampleArray = array(
      'firstfield' => (string)"Person",
     'thirdfield' => (integer)'Quantity',
     'fourthfield' => (string)'Product'
  );

Then i will save the $sampleArray to db.  

I hope I am being clear enough.  Please let me know if not.  Thank you very much.

Without seeing data or code it's difficult to guess what you need, but if you want to add new values to an array in a loop then you need to include the square brackets to indicate it's a new element within the array, otherwise you'll just overwrite what you already have:

Here's an idea for you to play with:

$sampleArray = array();

foreach($test as $k=>$sampleEntry):
   $sampleArray[$k] = $sampleEntry;
endforeach;

var_dump($sampleArray);
