how to insert the variables from the loop into an associative array in php

Question

I have the following loop:

 foreach($_POST as $key => $value) {

           echo "Key:" . $key . " Value: ". $value .   "<br />";         

           }

which produce the following result:

Key:1 Value: my value Key:8 Value: my some other value Key:9 Value: another value

What I am trying to do is to create an array that would look like this:

$editWhat = array(
                'field1'            => $key1,
                'field2'            => $key2,
                'field3'            => $key3,
                'field4'        => $value1,
                'field5'        => $value2,
                'field6'        => $value3
            );

Comma should be stripped in the last value pair line in the array, which cause me additional problems.

Any help will be deeply appreciated.

Regards, John

Are you trying to create an array with those key, value pairs, or are you simply trying to print them to look like an associative array? — jonhopkins

Okay, then the answers below are correct. I just wasn't sure, because the code you posted is all about printing out the array. — jonhopkins

$editWhat = array();
foreach($_POST as $key => $value)
    $editWhat['field'.(count($editWhat)+1)] = $key;
foreach($_POST as $value)
    $editWhat['field'.(count($editWhat)+1)] = $value;

will do exactly what you described. If you don't need the keys of the array you can do:

$editWhat = array_merge(array_keys($_POST), array_values($_POST));

To the one how downvoted me: can you explain why? Is there a mistake or am I missing something?

Maybe I misunderstand but try this to get your desired array:

$editWhat = array();
$count = count($_POST);
foreach($_POST as $key => $value) {
    $editWhat['field'.($key+1)] = $key;
    $editWhat['field'.($key+$count+1)] = $value;
}

Just set the array values to the corresponding key within the loop:

$editWhat = array();

foreach($_POST as $key => $value) {

    $editWhat[$key] = $value;  

}

see http://php.net/manual/en/language.types.array.php

           $editWhat[$key] = $value;

You can use array_keys() and array_values() functions to loop through keys and values of array and using two separate loops construct a new array.

Try this.

foreach($_POST as $key=>$value){
    $keys[]=$key;
    $values[]=$value;
}
foreach($keys as $editKey){
    $editWhat[]=$editKey;
}
foreach($values as $editValue){
    $editWhat[]=$editVlaue;
}

why do you store the keys and values before you loop over them? You could use array_values() and array_keys() or simply loop over the $_POST and directly insert into $editWhat.

 $array = array();
$n = 1;
foreach($_POST as $key => $value) {
      $array["field".$n] = $key; 
      $n++;
 }

foreach($_POST as $key => $value) { 
      $array["field".$n] = $value; 
      $n++; 
}

print_r($array);
