PHP split a very big number

Question

I used a number below in my code:

$MyString = '068875581086163483346499660139294';

When i'm trying to split MyString into a same pieces for example: 06887558, 10861634 so on... using substr or str_split that gives me:

06887558, 10861634, 8â€‹3346, 4996â€‹6, 0139294

Someone explain why this happend?!?

The Code what I have tried

$MyNewString; $n = 8; // How many you want before seperation 
$MyNewString = substr($MyString,0,$n); 
$i = $n; 
while ($i < strlen($MyString)) { 
    $MyNewString .= '-'; // Seperator Character 
    $MyNewString .= substr($MyString,$i,$n); 
    $i = $i + $n; 
} 
echo $MyNewString;

Please provide the exact, complete, minimal code necessary to reproduce this exact problem. — deceze, Apr 21 '14 at 07:44

Also used str_split($MyString,7) to split into 8 parts but there was no different. — wertvoll, Apr 21 '14 at 07:50
Your string contain special characters. copy your string and paste it in editor, it will display `?` like characters. — Bindiya Patoliya, Apr 21 '14 at 07:50

$new_string = implode(', ', str_split($n, 8));
echo $new_string;

If you're getting funny characters in the result, then they must have been in the original string. substr and str_split don't add anything.

I copied your $MyString and print it. It gives '06887558108616348â€‹33464996â€‹6013929406887558'. So, your string have some characters. Please avoid it – Rohit Subedi Apr 21 '14 at 07:54

It's better to use `header('Content-Type: text/html; charset=utf-8');` – Ja͢ck Apr 21 '14 at 07:58
@Jack you are right. I just give one of the solution. not best solution – Md. Sahadat Hossain Apr 21 '14 at 07:59
Also, this only masks the problem; the real issue is with the string contents which should be cleaned up to only contain numbers. – Ja͢ck Apr 21 '14 at 08:04
