What is the difference between echo and print and printf in PHP?
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.

Why php Echo not printing output with parenthesis?
echo will not return output when using parenthesis because echo is not a function like print. echo is a language construct. The benefit to using echo over the print function is speed, plus you can separate data types using comma's rather than periods.Example:echo 'This is a string ' , $variable , ' ending string';is the same (but faster) as:print('This is a sting' . $variable . ' ending string');

What is difference between language constracter and function for exampal echo print in php language?
I think you mean language construct... Anyway, a function usually takes one or more arguments as comma separated values or variables. echo and print don't <?php $email = 'user@example.com'; $domain = strstr($email, '@'); echo $domain; // prints @example.com ?> Here the strstr function takes a variable string and a constant string as an argument. echo simply displays the contents of the resulting variable. There are a couple functions that don't require arguments, like die() & exit()
