echo()

The echo() outputs one or more strings. PHP echo() is not actually a function, so you are not required to use parentheses with it. However, if you want to pass more than one parameter to echo(), using parentheses will generate an error and these parameters must not be enclosed within parentheses.

Examples:

<?php

  $number = 1;
  echo "String" . "Another string";
  echo "<br />";
  echo "String" . $number;

?>

 

We can use string concatenation to add strings together. If you look closely at examples above, you will see that these strings are separated with a period(.) between them. As well we can do that for string and variable name.

By echo "<br />"; we add a new row in our script.
