How to Check PHP Code Online

How to Check PHP Code Online

Whether you are trying to write PHP code or you are a developer who needs to run the code on your server, you can easily check if the code is correct. You can also check for syntax errors and make sure that your PHP version is up to date.

Check your PHP version

Keeping PHP up to date is important because it protects your site from vulnerabilities. Moreover, it helps to improve your site’s performance. If your PHP version is old, it may slow down your website. In addition, it will not use server resources efficiently. This can also negatively affect your search engine rankings.

To check your PHP version online, visit your host’s control panel. You will find a number of tools there that can help you determine the right version. Some companies offer bespoke hosting panels, while others use industry-standard cPanel. However, most major hosts offer PHP tools. You can also check the PHP version using the command line.

You can use the php -v command to check the PHP version of your server. The command prints the version, as well as other information about the PHP server. It can be used on both supported systems and remote servers.

You can also check your PHP version using the Site Health Check tool. This tool was introduced with WordPress 5.1 and scans for common performance issues. If your PHP version is outdated, it will recommend ways to upgrade. You can then select one of the recommendations to learn more.

When you run the Site Health Check, you will see a report divided into two sections. The Status tab will show the PHP version and the Info section will display your web server’s architecture, as well as the maximum input variables of PHP. You will also see the copyright and X-Powered-By headers.

You can then contact your host support team for more information. If you are unable to change the PHP version, you can have a qualified hosting provider do it for you.

Find syntax errors

Using a PHP error checker online is a good way to find syntax errors in your code. This tool will highlight the errors, making them easy to find and fix. But before you start checking your code, you should know a few important things.

The first step is to determine the type of error. You can do this by examining the error message in your code. It may contain the line number of the error, giving you a rough idea where to look.

The other way to identify the location of a syntax error is to check the file. The file tells you where the error is and how to resolve it.

If you are experiencing a parse error, it means that the PHP interpreter has detected a missing element. This can be a semicolon, a comma, or a closing bracket.

When you see a warning or fatal error, it means that the code you are executing is incorrect. It could be caused by an undefined function or class. It will need to be fixed before your code can be executed.

Usually, fatal errors require refactoring or a code change before the error can be fixed. This means that you will need to rewrite your code to conform to current standards.

If you are having a hard time finding the source of a syntax error, you can try restoring a previous version of your site. The process of restoring a website depends on what software you used. You can also back up your site before you make a change. This will overwrite any changes you have made since the backup was taken.

Lint is a type of check that checks your code for common syntax errors. If you want to check your code in the future, you should use a versioning system.

Run the code on your server

Generally speaking, PHP code does not run locally. Rather, it runs on a web server. However, you can write some PHP scripts that run on your own computer.

One of the simplest ways to do this is to use a tool called a Terminal. This is a program that you can use on Macintosh computers. It is typically found in the menus of the Mac OS X desktop. You can use it to perform a variety of tasks, including using a command line.

This is especially useful when writing a small PHP script. You can use it to compile and output the most important function of the PHP script.

The same is true if you want to perform an even more simple operation. If you aren’t familiar with how to do this, you can use an online PHP compiler to view the script’s code in your browser.

Normally, you can’t see the code that is being written to your server. This is because the code is being compiled and processed by the Zend Engine.

But, if you are willing to put in the effort, you can get a preview of what the finished script will look like in your browser. The function that does this is called the phpinfo function. You can find it on the Tools section of the Server Configuration page.

The phpinfo function will also tell you how the script is installed. For example, if you have Apache and NGINX installed, the phpinfo function will show you that the script is installed in a folder called htdocs.

You can learn more about PHP at the official PHP website. This site contains information about the various functions of the PHP script as well as links to download the software.


Using an online PHP code runner tool is a great way to find errors in your PHP scripts. The code runner allows you to test your PHP scripts in the browser without having to install any desktop apps or browser plugins. In addition, the tool will highlight all syntax errors in your scripts, saving you time and effort.

The tool also includes Lint, a type of custom check that checks your scripts line by line for common errors. These errors are highlighted in the browser, saving you time and effort. You can also jump to a specific error to quickly fix it.
