In PHP there are two basic ways to get output: echo
and print
.
In this tutorial we use echo
(and print
) in almost every example. So, this chapter contains a little more info about those two output statements.
echo
and print
are more or less the same. They are both used to output data to the screen.
The differences are small: echo
has no return value while print
has a return value of 1 so it can be used in expressions. echo
can take multiple parameters (although such usage is rare) while print
can take one argument. echo
is marginally faster than print
.
The echo
statement can be used with or without parentheses: echo
or echo()
.
