PHP Strings

A string is series of characters, where a character is the same as a byte, so PHP only supports a 256-character set.

How to use Strings

Single quoted strings

echo 'Hello World';

Double quoted strings

echo "Hello World";

Double quoted strings with variable

echo "$var1 Hello World";

Double quoted strings with variable inside curly braces

echo "{$var1} Hello World";

Concatenating Strings

echo "Hello" . " World";
echo "Hello" . $var1;
echo getvar1() . "Hello";
