Your First Script

Your first script will generate the traditional "Hello, World!" greeting on the command line. Follow the simple steps below.

1. Type

   cd

   to get to your home directory.

2. Type

   mkdir PHP

   to create a new directory called PHP.

3. Type

   cd PHP

   to descend into the newly created directory.

4. Using vi, vim or some other editor, create a new file called hello_world.php.

5. Type in the following lines:

   <?php
   echo "Hello, World!\n";
   ?>
    
   From the command line inside the PHP directory which you created, type
   php -f hello_world.php
   
   

Notes

• <?php informs PHP (or a server) that the following is PHP code.
• ?> informs PHP (or a server) that it has reached the end of the PHP code.
• echo is a function which outputs the specified information. Here the words Hello, World! are printed. The quotation marks enclose what is to be printed. The \n is the newline character.
• The -f you typed in the command string tells the php executable that the next element is the file to be processed.
