- PHP Function
- Create a PHP Function
- - Syntax
  - 1. function functionName()
    2. {
    3. code to be executed;
    4. }
    Give the function a name that reflects what the function does
    The function name can start with a letter or underscore (not a number)
  - - Example
    - A simple function that writes my name when it is called:
      <html>
      <body>
      <?php
      function writeName()
      {
      echo "MONA";
      }
      echo "My name is "; writeName();
      ?>
      </body>
      </html>
      
      Output:
      
      My name is MONA
- PHP Functions - Adding parameters
- - Example 1
  - - The following example will write different first names, but equal last name:
    2. <html>
    3. <body>
    4. <?php
    5. function writeName($fname)
    6. {
    7. echo $fname . " BRT.<br />";
    8. }
    9. echo "My name is "; writeName("MONA");
    10. echo "My sister's name is "; writeName("Hege");
    11. echo "My brother's name is "; writeName("Stale");
    12. ?>
    13. </body>
    14. </html>
    15. Output:
    16. My name is MONA BRT
