  Whatever text or var inside the command will be displayed inside of the webpage.

  echo(“test”); – that will print the word “test” on the webpage

  $text = “test”;
  echo($text); – that will also print “test” on the page.

  Hi Hamlet,

  The PHP builtin function echo(), just like the print() one are used to output text. Basically, both functions work the same, try it:

  Step 1) Create a file, save it as PHP, e.g. “test.php”

  Step 2) Edit the file by adding the following code:

  < ?php

  // this is a comment, it will be ignored

  echo '1';
  echo ('2');
  echo '3';
  print '4';
  /*
  another comment (this time, a multiline one)
  what I'm doing here is to show you different
  ways to output text inside browsers using PHP
  */
  ?>

  Step 3) Save the “test.php” file after you’re done with the editing part.

  Step 4) Put “test.php” on your webserver, and access it using your browser at http://serverhostname/test.php – You will see on the page, the following text, based on the example provided at step 2:

  —————– browser top ———————
  1234
  —————– browser bottom —————-

  Enjoy

  echo() is the same as print() except it supports multiple expressions where as print cannot. Both output a string.

  example: echo “The first”, “the second”;

  echo is to output to the screen. if the name is confusing -

  use print(); – it is the same thing.
