Imploding $_POST values with comma

Question

I have a textarea in my form where user will enter data line by line. I am processing it using $_POST . I have to separate each line by a comma while echoing it in php

the text area content like this

233
123
abf
4c2

I tried with below code

$array = array($_POST['devices']);
$device = implode(",", $array);

echo $device;

But it not showing commas between each value, rather I will get plain values like

233 123 abf 4c2

How can I show it like

233,123,abf,4c2

All above values are part of the text area,

A textarea gets sent to the server as a simple string. it is NOT an array that you can implode. — Marc B, Jul 25 '13 at 18:36

You can not split a string into an array simply by creating an array().

You need to convert it to an array by splitting the lines:

$devices = preg_split('/\s+/', $_POST['devices']);
echo implode(',', $devices');

Note: You may want to split strictly on line endings. But the above will get you started.

for that matter you could do `preg_replace('/\s+/', ',', $_POST['devices']);` and skip the implode – Orangepill Jul 25 '13 at 18:44

No need to summon the power of regular expressions. You can simply implode the results of an explode.

$str = implode(",", explode("\n", $_POST['devices']));
