how do i insert a comma in string like
$str = "0470 06102009 2981485GIR ADE TAUHID";
every length i put in array like
$legth = array(7,8,15,50);
i just wanna make the result like
0470 ,06102009 ,2981485GIR ,ADE TAUHID
where every string splited according to length on the array, including whitespace,
length(7),length(8),length(15),length(50)
how i do that ?

Answer 1

I would do something like this:
$offset = 0;
$result = implode(",",array_map(function($length) use ($str,&$offset) {
$part = substr($str,$offset,$length);
$offset += $length;
return $part;
},$legth));

Please note that the output of the demo is what you "should" get based on the input you provided. Your input is wrong for the output you say you want - adjust $legth as needed.

Answer 2

if you are sure of the number of spaces and you want to keep them, you can use substr
// substr( your string, start, length )
substr($str , 0, 7)

Answer 3

This will work for you:
$oldString = "0470 06102009 2981485GIR ADE TAUHID";
$newstring = implode(", ", preg_split("/[\s]+/", $oldString));
echo $newstring;
EDIT:
If you need output on the basis of your array. Then I think you need to modify your array first. And apply below code:
$legth = array(7,8,15,50);
$str = "0470 06102009 2981485GIR ADE TAUHID";
$first = 0;
foreach($legth as $l){
echo substr($str , $first, $l)."<br />";
$first = $first + $l;
}
