echo is a language construct(You can see we don't use
paranthesis for echo).echo does not return any value. print
is also a language construct but it returns an integer
value. printf is a function..... echo is considered fast

Answer / shilpa yogesh agrawal

echo, print and printf are used for printing strings but the
basic difference between them is: echo is the most primitive
of them, and just outputs the contents following the
construct to the screen. print is also a construct (so
parentheses are optional when calling it), but it returns
TRUE on successful output and FALSE if it was unable to
print out the string. And you can pass multiple parameters
to echo, like:

and it will output the string “Welcome Jack”

Whereas print does not take multiple parameters. It is also
generally argued that echo is faster, but usually the speed
advantage is negligible, and might not be there for future
versions of PHP.

printf� is a function, not a construct, and allows such
advantages as formatted output, but it’s the slowest way to
print out data out of echo, print and printf.
