PHP echo and print

echo and print are language constructs, not functions. This means that they don't require parentheses around the argument like a function does (although one can always add parentheses around almost any PHP expression and thus echo("test") won't do any harm either). They output the string representation of a variable, constant, or expression. They can't be used to print arrays or objects.


  • Assign the string Joel to the variable $name

  • $name = "Joel";

  • Output the value of $name using echo & print

  • echo $name;
    print $name; 

    Output

    Joel
    Joel

  • Parentheses are not required, but can be used

  • echo($name);
    print($name);

    Output

    Joel
    Joel

  • Using multiple parameters (only echo)

  • echo $name, "Smith";
    echo($name, " ", "Smith"); 

    Output

    JoelSmith
    Joel Smith

  • print, unlike echo, is an expression (it returns 1), and thus can be used in more places:

  • print("hey") && print(" ") && print("you");

    Output

    Differences between echo and print


    • print only takes one parameter, while echo can have multiple parameters.
    • print returns a value, so can be used as an expression.
