PHP: Read out first Character from String

Question by Guest | 26/06/2015 at 23:14

How is it possible to specify the first character from an arbitrary string in PHP?

For example, given the string "abc", I would like to get the letter "a" as a result.

Is there any function for that in PHP?

Here are two examples showing two possibilities to extract the first character from a string.

$s = "abc";

echo $s[0];             // a
// or
echo substr($s, 0, 1);  // a

First of all, it is possible to access individual characters of a string by using square brackets. The first character of a string has the position 0, so we can read out this character via $s[0].

The second possibility I am showing in the example, is using the PHP function substr() for the same purpose. As starting position (second parameter) of our substring we are passing the beginning of the string (that is 0) and as number of characters to be extracted (third parameter) we are specifying 1 to get exactly the first character from the string.
