When scripting in PHP, you always want to open up the script with a tag and close it with a ?>tag.
We can use php tags in different ways. <?php //php code to be written here ?> OR <? //php code ?> This tag will not work when we using editors such as macromedia dreamweaver. OR < script language="php"> //php code </script>
< ?php // This is an example of comment in PHP /* This is another example of comment in PHP and we can write comments in multiple lines using this method */ ? >
To compile PHP code, you do not use a traditional compiler like you would with languages such as C++ or Java. PHP is an interpreted language, meaning the code is executed directly by the PHP interpreter. To run PHP code, you need a web server with PHP installed, such as Apache or Nginx. The PHP interpreter reads the code, processes it, and generates the output dynamically.
The PHP question mark "<?" is a signal to the web server that everything up until "?>" will be PHP code and should be treated accordingly.
`<?php` then a `?>` and also `<?=` and `?>` are the only compliant methods now that PHP 7 is out.
PHP is an open-source scripting language used to code websites and webpages. An index php is a page used on a web server as the main frontpage for the website.
PHP is related with HTML. HTML can be included into PHP script as well as PHP script can be included into HTML code. PHP begins and ends with <?php ?>. PHP is mix of few languages so semantics is mixed too.
The GET method in PHP allows you to grab information from the URL to use in your script.For example, say you are on the URL index.php?id=1 you could then in the PHP script grab the id using the GET method to use in your script.
We can use php tags in different ways. <?php //php code to be written here ?> OR <? //php code ?> This tag will not work when we using editors such as macromedia dreamweaver. OR < script language="php"> //php code </script>
< ?php // This is an example of comment in PHP /* This is another example of comment in PHP and we can write comments in multiple lines using this method */ ? >
I have little idea of your question however <?php #code in here ?> is the starter for PHP, and then anything outside is HTML.

You cannot call the print function from within PHP code. This is mainly because the PHP code is run server-side, and the printer is firmly part of the client's individual setup. That said, you can use JavaScript to politely ask the browser to print the document. The call will cause the browser to bring up its default print dialog. The specific JavaScript method you're after is window.print();
PHP code blocks start with <?php and end with ?>.
The file extension for PHP is .php
PHP and C are two different programming languages that cannot directly interact with eachother. You can have a program made with C call a PHP script, using its output (an indirect interaction), but there's no way to "embed" PHP into C code.
PHP is server-side, the browser itself does not interpret it. Rather, the browser sends a query to the server, and the PHP scripting generates custom HTML document. It is this HTML that you are seeing the source code of.
