On the off chance that you are inquiring as to whether there is anything exceptional you have to know before you begin learning PHP, the answer is no. Simply jump into the PHP: Documentation and begin.
One reason for PHP’s prosperity is that it has truly awesome documentation. Each idea is separated in straightforward terms and clarified completely. What’s more, on every page, guests to the site remark and fill in more cases and missing subtle elements.
PHP is likewise one of the least complex and most clear scripting dialects. This makes it simple to learn.
In order to use PHP effectively, you will eventually need to learn other languages, such as:
HTML, since it’s what PHP typically yields to the program
MySQL, on the grounds that you’ll need to store client information in a database
CSS, on the grounds that it’s the means by which you add style to HTML pages
I listed those in the request that I suggest you learn them. However, I prescribe that you begin with PHP.
