Get First 2 Characters In a String

Question

I'm trying to get first 2 characters in a string. Here's my code:

$s = 'hello'; // line 4
printf("[%0.2s]\n", %s); // line 5: Gets first 2 characters [he]

It's giving me an error:

Parse error: syntax error, unexpected '%' in C:\laragon\www\karakter_tamamlama.php on line 5

Why am I getting error?

Hello, I'm not asking how to get first 2 chars. I'm asking why I'm getting an error. — Onur Can, Dec 07 '17 at 07:19

$s instead of %s

printf("[%0.2s]\n", $s);

or

substr($s, 0,2);

Use substring function to get letters from string.

An example:

substr($s, 0, 2)

Second arg should be $s, see printf()

printf("[%0.2s]\n", $s);
