php - Sub-string without counting blank spaces

Question

I want to make a sub-string, where the $count only counts letters, not spaces. This is what I have so far:

$string ="vikas tyagi php";
$string = substr($string, 0, 10);
echo $string;

Output:

vikas tyag

Desired output (I don't want to count the spaces):

vikas tyagi

How would I do this?

i want extract string with those condition

1)Base on count letter

2)Without white space

3)String limit also

Answer 1

Simply count the spaces and add them to the desired length of the capture:

function spaceless_substr($string, $start, $count) {
    return substr($string, $start, ($count+substr_count($string, ' ', $start, $count)));
}

$string ="vikas tyagi asd sd as asd";
echo substr($string, 0, 14);
// return: "vikas tyagi a"
echo spaceless_substr($string, 0, 14);
// return: "vikas tyagi asd"
