In HTML, PHP tag is applicable for the PHP codes in HTML documents. PHP tag is embedded in an HTML document and is placed anywhere on the HTML document page. Whenever the PHP tag is embedded with the HTML page, it parses the document and also interprets the section. It is enclosed with the opening and closing tags and ignores the rest of the web documents. PHP is an HTML embedded server-side scripting language. Some PHP syntax is followed with java and another scripting languages. It is also used for developers to create dynamic web pages more quickly.
Syntax:
HTML has lots of tags for users to build a complex web page. Sometimes we will face and combine the PHP and HTML to achieve the results.
<html> <body> <?php ---some php code syntax--- <?> </body> </html>
The above code is the basic syntax for the PHP scripts in HTML language. We will use some HTML predefined tags in the web-based documents, and also some browsers will be compatible for some times, or else we will add the Extension plugin in the browsers to view and support the PHP scripts in the web pages.
If we use PHP tag in HTML, it was shortened to the code as much as possible for the short tags options. This will help for saving time for typing the codes from
If the problem may occur by using some short tags, it will conflict more with the XML tags usages. Because the XML tags Starting the tag for processing the function to avoid this type of problem in the HTML, we will use = this tag will be used for the HTML. In every HTML page, PHP code is enclosed within some special PHP tags; whenever the visitor visits the web pages, the request is sent by the client, and the server will receive the request and sent the response to the client that time the server uses the PHP code.
We will integrate the HTML code with PHP, and then the PHP script is considered as an HTML page with some PHP code is inserted with the HTML document anything in the PHP code we will consider as an tags and is ignored with the default PHP compiler, and it passed directly to the web browsers. Whenever we create the PHP file or receive the file, it should be contained with the PHP code, and it must have a PHP extension. In most cases, this comes with a .php extension and also, we can also configure with the .htaccess file to read the PHP code in the given HTML file without renaming it and changing the extension.
PHP looks like a bit complicated, and also it actually saves a lot of codes, and also sometimes it saves and by using the codes with the help of some tags like “$PHP_SELF,” it’s a superglobal it allows us to use the values of the particular fields specified with under some conditions in it in the same file. We create the first normal HTML file that is a front end page, and it will be helpful for sending the user request to the server and the second thing is the backend; it’s nothing but the PHP extension file will receive the user request and sent the response to the user.
If the web application we created using PHP, it will be more complicated, i.e.) it requires more files to deploy the server, and we need all the files to be kept as simple as possible can be an assistance one. PHP will have the facility to remove some blocks if the required input condition is not validated; if the PHP code is used for another file in the web page, it will be removed from the basic condition even though the PHP interpreter is jumped from both the blocks it also satisfied with the basic conditions. The large blocks of the code will be removed from the PHP parsing mode; it will consider as an efficient one compared to sending the messages through a command like “echo” or “print” statements.
Given below are the examples of PHP Tag in HTML:
Code:
<html> <body> <?php echo 'Welcome To My Domain!'; ?> </body> </html>
Output:
Code:
<html> <body> <h1>Date and Time</h1> <?php $dates_arrays = getdate(); foreach ( $dates_arrays as $keys => $val ){ print "$keys = $val<br />"; } $date_formatted = "Today's date: "; $date_formatted .= $dates_arrays['mon'] . "/"; $date_formatted .= $dates_arrays['year'] . "/"; $date_formatted .= $dates_arrays['mday']; print $date_formatted; ?> </body> </html>
Output:
Code:
<?php session_start(); if( isset( $_SESSION['counters'] ) ) { $_SESSION['counters'] += 1; }else { $_SESSION['counters'] = 1; } $msgs = "Welcoe To My Domain ". $_SESSION['counters']; $msgs .= "Users."; ?> <html> <head> <title>Welcome Users</title> </head> <body> <?php echo ( $msgs ); ?> </body> </html>
Output:
上記の 3 つの例では、HTML を使用して Web ページを作成するバックエンドで Web ページに使用される PHP タグについて説明します。 HTML Web ページに PHP コードを記述すると、通常、PHP コードの使用中にファイルは .html 拡張子で保存されますが、.html 拡張子では機能しません。 HTML Web ページで PHP コードを実行するにはエディタが必要です。また、PHP フレームワークをサポートするオープンソースの無料 HTML エディターもインストールします。
一般に、PHP ではファイルをサーバーにアップロードするのが簡単です。一部の多国籍企業は、「Facebook、Twitter、Instagram など」と同様に、サーバーサイドのスクリプト言語会社として PHP を選択します。 PHP は、メールなどの高度な機能もサポートしますが、AJAX、XML などとも組み合わせられます。
