Combining PHP and HTML – Code with examples
Write the following code, inside a new file created with our favorite editor, making sure to save it with a name whose extension is .php, for example: hello.php.
The key concept: completing the HTML pages inmediately
We are going to create, try and try to understand our first PHP code
- Write the following code, inside a new file created with our favorite editor, making sure to save it with a name whose extension is .php, for example: hello.php
This will be the code of hola.php:
<html>
<head>
</head>
<body>
<p>This was written in HMLT</p>
<?php
print (“<p>Hello world! This was written by the PHP interpreter </p>”);
?>
</body>
</html>
This file must be saved inside the root folder of the Web server that we have installed.
- • We turn on the local server software
The Web server software will be waiting for you to request, through a browser (Explorer, Firefox, Opera), any of the files you have ready to serve us. In this case we will ask for the file hola.php
- To do this, we will open the browser and write the necessary URL to request the Web server the file hola.php. This is a key issue
On a PC with a local Web server we must write:
http://localhost/ejercicio1/hola.php
or using the local IP address
http://127.0.0.1/ejercicio1/hola.php
Attention:
It will not work to go to the File menu à Browser file, since our PHP file needs to be processed by the PHP interpreter program installed on the Web server, which should be on.
It also does not work for those who have Dreamweaver, press F12, for the same reason. Nor does it work to double-click the PHP file.
In all those erroneous cases, if you look at the URL, it will not mention anywhere http: //localhost/ejercicio1/hola.php. For this reason, the Web server software and the PHP interpreter will not process that file.
Once requested the URL of the file from our browser, and after waiting a few seconds, the source code that was processed on the server will arrive to the browser. From this moment, in which the generated code arrived at our browser, we can access the source code that was delivered to our browser (using the menu: View à Source code) and, in this example, we will see that what has arrived following:
<html>
<head>
<title>Hola</title>
</head>
<body>
<p>Esto estaba escrito en HMLT</p>
<p>Hola mundo! Esto lo escribió el intérprete de PHP</p>
</body>
</html>
Which means: the PHP interpreter erased all the orders that it found between the marks <?php and ?>, Which are the ones that indicate the beginning and the end - respectively - of an area in which the PHP interpreter is going to be given orders and, instead of what he had written there, he wrote, using the print function, the text:
<p>Hello world! This was written by the PHP interpreter </p>
