Summary<\/strong>: in this tutorial, you’ll learn how to execute a script that outputs the Hello, World!<\/code> message on the web browser and command line.<\/p>\n\n\n\n

PHP Hello World on the web browser #<\/a><\/h2>\n\n\n\n

First, open the folder htdocs<\/code> under the xampp<\/code> folder. Typically, it is located at C:\\xampp\\htdocs<\/code>.<\/p>\n\n\n\n

Second, create a new folder called helloworld<\/code>.<\/p>\n\n\n\n

Third, create a new file called index.php<\/code> under the helloworld<\/code> folder and place the following code in the file:<\/p>\n\n\n

<!DOCTYPE html>\n<html lang=\"en\"<\/span>>\n<head>\n    <meta charset=\"UTF-8\"<\/span>>\n    <meta name=\"viewport\"<\/span> content=\"width=device-width, initial-scale=1.0\"<\/span>>\n    <title>PHP - Hello, World!<\/title>\n<\/head>\n<body>\n        <h1><?php<\/span> echo<\/span> 'Hello, World!'<\/span>; ?><\/span><\/h1>\n<\/body>\n<\/html><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
The code in the index.php<\/code> file looks like a regular HTML document except for the part <?php<\/code> and ?><\/code>.<\/p>\n\n\n\n
The code between the opening tag <?php<\/code> and closing tag ?><\/code> is PHP:<\/p>\n\n\n
<?php<\/span> echo<\/span> 'Hello, World!'<\/span>; ?><\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
This PHP code prints out the Hello, World<\/code> message inside the h1<\/code> tag using the echo<\/code> statement:<\/p>\n\n\n\n
When PHP executes the index.php<\/code> file, it evaluates the code and returns the Hello, World!<\/code> message.<\/p>\n\n\n\n
Fourth, launch a web browser and open the URL:<\/p>\n\n\n
http:\/\/localhost:8080\/helloworld\/<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
If you see the following on the web browser, then you’ve successfully executed the first PHP script:<\/p>\n\n\n\n
\"PHP<\/figure>\n\n\n\n
If you view the soure code of the page, you’ll see the following HTML code:<\/p>\n\n\n
<!DOCTYPE html<\/span>><\/span>\n<html<\/span> lang<\/span>=\"en\"<\/span>><\/span>\n<head<\/span>><\/span>\n    <meta<\/span> charset<\/span>=\"UTF-8\"<\/span>><\/span>\n    <meta<\/span> name<\/span>=\"viewport\"<\/span> content<\/span>=\"width=device-width, initial-scale=1.0\"<\/span>><\/span>\n    <title<\/span>><\/span>PHP - Hello, World!<\/title<\/span>><\/span>\n<\/head<\/span>><\/span>\n<body<\/span>><\/span>\n        <h1<\/span>><\/span>Hello, World!<\/h1<\/span>><\/span>\n<\/body<\/span>><\/span>\n<\/html<\/span>><\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
PHP Hello World on the command line #<\/a><\/h2>\n\n\n\n
First, open the Command Prompt on Windows or Terminal on macOS or Linux.<\/p>\n\n\n\n
Second, navigate to the folder c:\\xampp\\htdocs\\helloworld\\.<\/p>\n\n\n\n
Third, type the following command to execute the index.php file:<\/p>\n\n\n
c:\\xampp\\htdocs\\helloworld>php index.php<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
You’ll see the HTML output:<\/p>\n\n\n
<html<\/span> lang<\/span>=\"en\"<\/span>><\/span>\n<head<\/span>><\/span>\n    <meta<\/span> charset<\/span>=\"UTF-8\"<\/span>><\/span>\n    <title<\/span>><\/span>PHP - Hello, World!<\/title<\/span>><\/span>\n<\/head<\/span>><\/span>\n<body<\/span>><\/span>\n        <h1<\/span>><\/span>Hello, World!<\/h1<\/span>><\/span>\n<\/body<\/span>><\/span>\n<\/html<\/span>><\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
Since the terminal doesn’t know how to render HTML to the web, it just shows the pure HTML code.<\/p>\n\n\n\n
To simplify the output, you can use the following code in the index.php<\/code>:<\/p>\n\n\n
<?php<\/span>\n\necho<\/span> 'Hello, World!'<\/span>;<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
If you execute the script again:<\/p>\n\n\n
c:\\xampp\\htdocs\\helloworld>php index.php<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
and you’ll see the following output:<\/p>\n\n\n
Hello, World!<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
When you embed PHP code with HTML, you need to have the opening tag <?php<\/code> and closing tag ?><\/code>. However, if the file contains only PHP code, you don’t need to the closing tag ?><\/code> like the index.php<\/code> above.<\/p>\n\n\n\n
Summary #<\/a><\/h2>\n\n\n\n
    \n
  • Place the PHP code between <?php<\/code> and ?><\/code> to mix PHP code with HTML.<\/li>\n\n\n\n
  • Use the echo<\/code> construct to output one or more strings to the screen.<\/li>\n<\/ul>\n
