PHP Echo(With Assignments)

 

PHP echo

PHP echo is a language construct, not a function. Therefore, you don't need to use parenthesis with it. But if you want to use more than one parameter, it is required to use parenthesis.

What is a language construct? 

A language construct is accepted/executed by the PHP parser as it is, in other words the PHP parser doesn't have to parse and modify a language construct to execute it, as it is ready for execution by default. Hence, language constructs are faster than any built-in functions.

syntax :

void echo ( string $arg1 [, string $... ] )

PHP echo statement can be used to print the string, multi-line strings, escaping characters, variable, array, etc.

Some important points that you must know about the echo statement are:

• echo is a statement, which is used to display the output.
• echo can be used with or without parentheses: echo(), and echo.
• echo does not return any value.
• We can pass multiple strings separated by a comma (,) in echo.
• echo is faster than the print statement.
