PHP echo and print statements

Differences between echo and print:

·                                                                                                                                                                                                                              Echo - can output one or more strings

·           print - only allows to output one string, the return value is always 1

Tips: The output speed of echo is faster than that of print. Echo has no return value, while print has a return value of 1.
