php array to comma separated string implode issues

Question

I'm having a problem in imploding an array to comma separated with double quotation. My Script is as below:

<?php

$arr = array(1,2,3,4,5,6,7,8,9);

$string = rtrim(implode('", ', $arr), ',');

echo $string;

The output is:

1", 2", 3", 4", 5", 6", 7", 8", 9

But I want this output below:

"1", "2", "3", "4", "5", "6", "7", "8", "9"

So anyone can help me with this problem please?

Thanks!

I smell a bigger problem… where are you going to use this imploded string exactly? — deceze, Sep 07 '16 at 07:56
`$string = '"' . implode('", "', $arr) . '"';`, this would solve it, but why would you need such output? — , Sep 07 '16 at 07:57
@deceze i am want to make a IPs output for a project that should be return like : '162.251.82.122', '162.251.82.250', '162.251.82.123', '162.251.82.251' — Shiv Singh, Sep 07 '16 at 08:00
And why does your "project" need a string in this particular format? Can't you use proper *serialisation*, e.g. JSON? — deceze, Sep 07 '16 at 08:01

I'll just throw this into the ring as alternative solution:

$string = trim(json_encode(array_map('strval', $arr)), '[]');

json_encode produces the desired result, just wrapped in a [..]; simply trim off the brackets.

try this,

$arr = array(1,2,3,4,5,6,7,8,9);    
$string = implode('", "', $arr);   
$string =  '"'.$string.'"';
echo $string;

OUTPUT :

"1", "2", "3", "4", "5", "6", "7", "8", "9"

You should have added the Opening and Closing Closing Double Quotes and No Need for the rtrim. The Following Code which you may test Here would do:

<?php

    $arr    = array(1,2,3,4,5,6,7,8,9);
    $string = '"' . implode('", "', $arr) .'"';

    echo $string;
