How to Avoid Trailing Commas When Creating Comma-Separated Strings from Object Arrays?

Generating Comma-Separated Strings from Object Array Columns

When working with databases and arrays of objects, it becomes necessary to generate comma-separated strings from specific columns. One common issue is having an extraneous comma after the last value.

To address this, a preferred method is to create a new array. For each object in the original array, extract the desired value and store it in the new array. This approach ensures that the last element will not have a trailing comma.

Here's an improved code snippet:

$resultstr = array();
foreach ($results as $result) {
  $resultstr[] = $result->name;
}
echo implode(",", $resultstr);
