One or more strings are output by PHP echo. It’s a feature of the language, not a function. As a result, there is no need to utilize parenthesis. If you wish to send more than one parameter to echo, you’ll need to use parentheses. PHP, on the other hand, prints a string. It’s a feature of the language, not a function. As a result, the argument list does not require the use of parentheses. In contrast to echo, it always returns 1.
Print can only output one string and always returns 1, but echo can emit one or more strings.
Because echo does not return a value, it is faster than print.
