php split array to string with commas

Question

i have an array with numbers

print_r($arr_usr_id[$key]);

output: "930933934"

now i need to convert this to 930,933,934 as a string with commas...

$newnumbers = (chunk_split($arr_usr_id[$key],3,","));

works but output: "930,933,934," gives me a comma after the last number

with str_split($arr_usr_id[$key], 3); i get three "Array" as output...

what is the best way to sepperate the numbers (from: 123145124984 to: 123,145,124,984,...) with commas?

Try to use str_split() with implode():

$newnumbers = implode(',', str_split($arr_usr_id[$key], 3));

<?php
header('Content-Type: text/plain');

$test   = '123456789';
$result = implode(',', str_split($test, 3));

var_dump($result);
?>

Shows:

string(11) "123,456,789"

@Jim on my side it is string(11) "930,933,934". Check your syntax.

$numbers = $arr_usr_id[$key]; var_dump($numbers); output: string(3) "930" string(3) "933" string(3) "934"

$newnumbers = implode(',', str_split($numbers, 3)); var_dump($newnumbers); output: string(3) "930" string(3) "933" string(3) "934"

if i enter manually numbers $numbers = "465444333"; this should work...it seems to be a problem with my array your method should work

@Jim try to check database encoding and php encoding to be compatible.

use:

number_format( $arr_usr_id[$key] );

implode(',', str_split($arr_usr_id[$key], 3));

or

substr(chunk_split($arr_usr_id[$key],3,","), 0, -1);

Perhaps? :)
