Question

I am wondering how to:

• Make comma-separated list
• Strip last comma from list

Here’s an array example:

Array
(
    [name] => Array
        (
            [0] => Some message to display1
        )
    [test] => Array
        (
            [0] => Some message to display2
        )
    [kudos] => Array
        (
            [0] => Some message to display3
        )

)

I want to display it like this:

Comma-List: Some message to display1, Some message to display2, Some message to display3

Answer 1

so, revising my answer to actually address your question, you could do it with nested foreach loops like this:

<?php

$a1 = array(
    'name' => array( 0 => 'Some message to display1'),
    'test' => array( 0 => 'Some message to display2'),
    'kudos' => array( 0 => 'Some message to display3'),
    );

$final = "";
foreach($a1 as $innerarray){
    foreach($innerarray as $message){
        $final .= $message.", ";
    }
}

echo substr($final,0,-2);
?>
