How to print Text in PHP

One can print text using different command of PHP.

1) echo is used to print anything as an output for example if you write echo “how are you?”; (remember each statement must end with a semi column, which is called termination mark).

2) print is also used to print , one can use it same as echo command for example

< ?php print “Hello”; ?> will print “Hello “ as an output.

What is the difference between echo and print? Which is faster, echo or print?

There is a difference between the two, but speed-wise it should be irrelevant which one you use. print() behaves like a function in that you can do: $ret = print “Hello World”;And $ret will be 1 That means that print can be used as part of a more complex expression where echo cannot.
