How to update PHP version?

1.What is PHP version?

PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e-commerce sites. It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.

 

2. Why does  the PHP version need to be updated?

  • Better security – The most obvious reason to update is security. Newer versions are better at countering hackers, for example, because deprecated (outdated) code is no longer supported.
  •  Faster websites – Newer PHP versions are faster. PHP 7.4 is significantly faster than the previous versions, and with faster execution times and less memory usage, especially WordPress sites will benefit.
  •  New features and improvements – As with all updates, a newer version includes new features and improvements on how to do things, for example, preloading.

 

3.How to check your current PHP version?

  • The simplest way to check your current PHP version running on your website  is to execute  to a PHP file that contains the code below.

<?PHP

echo 'PHP version: ' . phpversion();

  • Create a file with the help of editor such as  “Notepad” and upload it to the document root directory of your website
  • Then type the full address of the uploaded file in the address bar For example ,If you uploaded a file titled “currentphp.php” to the “example.com” root directory, then type  “https://www.example.com/currentphp.php”.
  • The code above displays the PHP version without any further details.
