What is echo in PHP
This statement is used to output the data to the screen or printing text on screen.
The echo statement can output one or more strings. In general terms, the echo statement can display anything that can be displayed to the browser, such as string, numbers, variables values, the results of expressions, etc.
Since echo is a language construct not actually a function (like if a statement), you can use it without parentheses e.g. echo or echo(). However, if you want to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.
Example:
The output of the above PHP code will look something like this: Devopsschool!

What is print in PHP
You can also use the print statement (an alternative to echo) to display output to the browser. Like echo the print is also a language construct not a real function. So you can also use it without parentheses like: print or print().
Both echo and print statement works exactly the same way except that the print statement can only output one string, and always returns 1. That’s why the echo statement considered marginally faster than the print statement since it doesn’t return any value.
