The cost of developing a website in PHP or WordPress depends on the project's complexity and the developer's skills. Generally, the cost of a website built in PHP will be higher than one built in WordPress due to the additional coding and programming time involved.
In both cases, some cost considerations include the time and effort needed to develop the website, the cost of hosting, and any additional software or plugins required. The cost of hiring a developer, designer, or another specialist to create the website may also need to be factored in.
