Your First Script

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

Type
```
cd
```
to get to your home directory.
Type
```
mkdir public_html/test_php
```
to create a new directory called PHP.
Type
```
cd public_html/test_php
```
to descend into the newly created directory.
Using vi, vim or some other editor, create a new file called helloworld1.php.
Type in the following lines:
```
<?php
echo "Hello, World!\n";
?>
```
From the command line inside the test_php directory which you created, type
```
php -f helloworld1.php
```

<?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 semicolon (;) terminates the single PHP statement, just as in C, C++ and Java.
The -f you typed in the command string tells the PHP executable that the next element is the file to be processed.
