Question

How can I check every character on a string on php?

For example I have this string.

$a = "sd qwerty utr";

I want to know the first of the string and get the 1st 3 characters, then I want to get the last 4 characters of the string.

The output will be "sd qwe utr".

There are two ways (your question doesn’t match your description):

1. You can use an index to get to each character individually:

   $a = "sd qwerty utr";
   $firstchar = $a[0];
   // etc
   

2. You can use substr() to get pieces of the string:

   $a = "sd qwerty utr";
   $part = substr($a, 0, 3);    // first 3 chars of string
