Question

I have a mysql fetch that is populating an associative array with columns from the DB.
One of the columns names is AMOUNT.
so it looks like this:

Array ( [0] => Array ( [ID] => 259 [YEARMONTH] => 201105 [AMOUNT] => 54 [VALUE] => 12 ) [1] => Array ( [ID] => 259 [YEARMONTH] => 201106 [AMOUNT] => 32 [VALUE] => 34 ) )

All I want to do is echo the AMOUNTs like this:

54,32

So that I don’t have trailing or heading commas.

Any suggestion for an elegant solution for this ?
Thanks !

Answer 1

Preconditions

• $array contains the array for all rows.

Code

foreach ($array as $row) {

    $newArray[] = $row['AMOUNT']; //Add it to the new array

}
echo implode(',',$newArray); //Implode the array and echo it out.

If you are using PHP 5.3+, this following also works:

echo implode(",",array_map(function($a) { return $a["AMOUNT"]; }, $array));

• implode – Takes an array and a delimiter and returns a string of ‘delimiter’ separated values of the array.
