Creating strings

Here are some examples of how to create strings in PHP using various methods.

Using Double Quotes

<?php
$string1 = "Hello, World!";
echo $string1; // Outputs: Hello, World!
?>

Using Single Quotes

<?php
$string2 = 'Hello, World!';
echo $string2; // Outputs: Hello, World!
?>

Using Heredoc Syntax

Heredoc syntax allows the creation of strings that span multiple lines and support variable interpolation.

<?php
$name = "John";
$string3 = <<<EOT
Hello, $name!
This is a string
created using Heredoc syntax.
EOT;
echo $string3;
// Outputs:
// Hello, John!
// This is a string
// created using Heredoc syntax.
?>

Using Nowdoc Syntax

Nowdoc syntax is similar to Heredoc but does not parse variables.

<?php
$string4 = <<<'EOT'
Hello, $name!
This is a string
created using Nowdoc syntax.
EOT;
echo $string4;
// Outputs:
// Hello, $name!
// This is a string
// created using Nowdoc syntax.
?>

Creating Empty Strings

<?php
$emptyString1 = "";
$emptyString2 = '';
echo $emptyString1; // Outputs nothing
echo $emptyString2; // Outputs nothing
?>

These are the primary ways to create strings in PHP.
