In PHP, a string can be created using single or double quotes. Here are some examples:
// Creating a string using single quotes
$string1 = 'Hello, World!';
// Creating a string using double quotes
$string2 = "Hello, World!";
// Concatenating strings
$greeting = $string1 . ' ' . $string2;
// Outputting the strings
echo $greeting; // Output: Hello, World! Hello, World!
