The echo() function outputs one or more strings.
void echo ( string $arg1 [, string $... ] )
Outputs all parameters. No additional newline is appended.
echo is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo (unlike some other language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if you want to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.
echo also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. Prior to PHP 5.4.0, this short syntax only works with the short_open_tag configuration setting enabled.
I have =$foo?> foo.
The major differences to print are that echo accepts an argument list and doesn't have a return value.
