How to convert array to string

I am new to PHP.

I want to convert this array [["14785"],["125478"]] to string like this 14785,125478.

What is the way to do this?

try this,

Using implode() - Demo

$array = ["14785"],["125478"]
$str = implode(',',$array);
echo $str;

Using join() - Demo

$array =  ["14785","125478"];
$str = join(",",$array);
echo $str;

EDIT

For multi-dimention array, - Demo

$arr = [["14785"],["125478"]];
$str = implode(',', array_map(function($el){ return $el[0]; }, $arr));

echo $str;

When I use implode function I get an error like Array to string conversion. my code is an array inside array.I have edited it properly now. – Adishri Kulkarni Dec 07 '15 at 11:28
can you format the array which you have added in proper way?? – Niranjan N Raju Dec 07 '15 at 11:30
This is my code [["14785"],["125478"]] I want like this 14785 so that I can compare it with another value. – Adishri Kulkarni Dec 07 '15 at 11:36
Glad I could help you:) – Niranjan N Raju Dec 07 '15 at 13:04
if its single dimention, use first method, if its multi dimention, use `array_map()` method. – Niranjan N Raju Dec 08 '15 at 05:43
yes but the problem I got again is length of that string is one not two.I want two separate strings.How would I solve this? – Adishri Kulkarni Dec 08 '15 at 06:13
I used implode function for multi-dimention array [["14785","2222"],["125478"]] but I got answer like this 14785,125478.where expected answer is like this 14785,2222,125478. How can I solve this? – Adishri Kulkarni Dec 08 '15 at 12:56

use php's implode function

$arr =  ["14785","125478"];
echo implode(",",$arr);

Without knowing the array structure it may not work, but for normal arrays this is the way.. – Svetoslav Dec 07 '15 at 11:13
join is faster than implode: http://dev.airve.com/demo/speed_tests/php/join_vs_implode.php `echo join(",",$arr);` – Thamilhan Dec 07 '15 at 11:14

@MyWay - `join()` is simply an alias for `implode()` so why do you believe that it's faster based on that arbitrary test page that you've linked..... the executed code is the same – Mark Baker Dec 07 '15 at 11:19

The link you came across is a pretty arbitrary tester that isn't consistent from one run to the next, so it can't be taken as absolute gospel truth.... it's meaningless – Mark Baker Dec 07 '15 at 11:23

Using implode()

 <?php
$arr = array('Hello','World!','Beautiful','Day!');
