Why Use Heredoc Syntax for Printing HTML in PHP?

Heredoc Syntax: A Novel Approach to Printing HTML in PHP

Traditionally, PHP developers have utilized variable interpolation or double quotes to render HTML. However, a relatively obscure feature known as heredoc syntax offers an alternative approach.

Heredoc syntax utilizes the <<< operator followed by an identifier and a newline character. The string itself follows, and the same identifier is used to terminate the quotation. In the provided example, the HTML code is embedded within <<

The use of heredoc syntax provides several advantages. It ensures that the embedded code is treated as a single string, reducing the susceptibility to variable interpolation errors or mismatched quotation marks. Furthermore, it allows for the convenient inclusion of multiline text without requiring concatenation.

The identifier EOB, as chosen by the author of the code, is an arbitrary designation and not part of the syntax. Developers are free to select any identifier that conforms to PHP's naming conventions, provided that it begins in the first column of the closing line.

In summary, heredoc syntax offers a versatile and error-prone approach to printing HTML in PHP. By utilizing a unique identifier, developers can embed multiline strings without the need for complex variable interpolation or concatenation techniques.
