What is Echo in PHP?

We should not confuse Echo statements in PHP with a function. It is basically a language construct that helps in defining the structure of code. Other examples of language constructs are for and while loops.

Echo statements in PHP are used to output single and multiple strings. It contains a list of expressions as an argument and does not have any return type. It can be used with or without parentheses as it is a language construct. One main disadvantage of using Echo statements is that they cannot be called by variable functions.

Syntax

echo(string ...$expressions)
echo string1, string2, …


We can use the expressions with or without parentheses, and It does not return anything.
